Published: March 2020

The present state of smelting of ferrosilicon manganese due to the deterioration of the quality of manganese concentrates is characterized by low extraction of manganese, silicon and an increase in the slag multiplicity. This requires the improvement of smelting technology with the use of charge materials with high reactivity, which is ensured by their preliminary preparation for melting.One method of preparation may be the method of mechanical activation of components separately or joint activation to provide high rates of the degree of recovery of elements in the metal phase.In order to attract mechanically activated fine materials for smelting of si-licomanganese, the basic technological requirements of preliminary preparation of briquetting briquette are grounded. Using hydrolysis lignin as a binder provides strong briquettes. At pressing pressures of 450-550 kg/cm2, the strength of the raw braces is 65-68 kg/cm2, and the fired in a reducing atmosphere at temperatures up to 1000оС, the strength reaches 160-185 kg/cm2.The study of the kinetics of joint carbon-thermal reduction of manganese and silicon at temperatures of 1250-1600 ° C with continuous weight loss control of the charge batch shows that the degree of recovery of the fractured, mechanically activated charge is 1.5 - 1.8 times higher than the reproducibility of the charge component 3- 0 mm and 2-3 times higher than the degree of recovery of the factory charge.Based on the results of chemical analysis of the experimental metal samples, it is shown that the application of mechanical activation in the joint processing of the mixture is significantly higher characteristics of extraction of manganese in the alloy by reducing the pre-formation of the slag phase and the recovery in this case of manganese from the slag melt

Published: March 2020

Specialists of metallurgy and mechanical engineering are intensively working at materials with controlled properties. In fact, at this stage we are already talking about the design of new materials for the specific tasks of the industry. One of the ways to achieve the regulated mechanical properties of metal products is to use the influence of plastic deformation with its different parameters in individual sections of the deformable material. In this study, we studied the effect of cold rolling on the properties of a strip of aluminum alloy EN AW-1050 with artificially created differences in the deformation parameters in different parts of the cross section of the profile. For this, a pre-shaped sample was prepared by conducting joint cold rolling of a strip of the specified material 420 mm long, 180 mm wide and 2.9 mm thick with a steel profiling tape 80 mm wide and 2 mm thick superimposed on it (length of an aluminum strip and steel profiling tape are the same). As a result of joint deformation, the steel strip rolled into the base metal and changed the geometry of the cross section and the properties of the obtained strip. Next, the obtained strip was subjected to heat treatment and rolled in a duo mill. After rolling, thin samples were made from fabricated flat strips to assess mechanical properties, in particular tensile tests were performed according to ISO 6892-1: 2009 and Brinell hardness tests were performed according to ISO 6506-1: 2014. Experimental studies of cold rolling of strips with profiled cross section of aluminum alloy EN AW-1050 were carried out. The possibility of forming heterogeneous properties in a flat aluminum strip by cold plastic deformation is shown and the maximum average values of the increase in the main indicators of mechanical properties on individual elements of the strip are determined. The maximum difference between the mechanical properties of the thick and thin elements of the profiled strip is observed in the hardness index and reaches 37.5%. The maximum obtained average value of the increase in yield strength and tensile strength is 26% and 18%, which is achieved with true deformation of the thick element of the profiled strip 0.165 and 0.234.
Assessment of the efficiency of non-metallic inclusions removal through the use of centrifugal force at different stages of steel production

Published: March 2020

Methods for the removal of non-metallic inclusions from steel at various stages of its production are considered: in a teeming ladle, a tundish and a CCM mold. It is proposed to classify methods of non-metallic inclusions removal into two groups: mechanical (inert gas blowing, application of electromagnetic stirrers, etc.) and physical and chemical (modification of non-metallic inclusions, slag treatment, rational deoxidation modes). Particular attention is paid to methods aimed at creating a vortex in the metal, inside which non-metallic inclusions are transported to its axis. The aim of the work is to determine the efficiency of use centrifugal forces to remove non-metallic inclusions at different stages of steel production. To assess the centrifugal force effectiveness, it has been analyzed the transfer time of non-metallic inclusions of various sizes to the vortex axis in the teeming ladle of 50 tons capacity, a rotary chamber of tundish (chamber capacity is 2.0 tons) and the CCM mold of 160 mm in diameter. For typical angular velocities being observed during electromagnetic stirring, the values of the metal inertia moment and the kinetic energy of its rotational motion have been calculated. According to the calculations, the smallest transfer time of inclusions is achieved in the teeming ladle. However, vortex creation in it requires a significant energy. The use of centrifugal force in the mold, although it does not require such a high energy, is also not efficient enough due to the low angular velocity of the vortex, limited by a risk of violating the crust formation in the mold. The possibility of using the kinetic energy of the jet flowing from the teeming ladle to the rotary chamber of the tundish has been assessed.

Published: March 2020

Розроблена математична модель свердловинної штангової насосної установки з балансирним приводом – верстатом-гойдалкою. Більшість свердловин Українських нафтових родовищ знаходяться на пізній стадії розробки, тобто їх дебіт нижчий ніж подача штангових насосів. Така робота верстатів-гойдалок приводить до зниження динамічного рівня рідини в свердловині, а отже й до зміни навантаження привода. Таким чином порушується усталений режим роботи. Коли рівень рідини досягає прийому глибинного штангового насоса, верстат-гойдалку відключають. На кривошипах верстата-гойдалки встановлено противаги, які зрівноважують навантаження, що діє в точці підвіски штанг. Зміна динамічного рівня призводить до порушення зрівноваження. Таким чином двигун привода перевантажується під час пуску верстата-качалки. Проведено аналітичне дослідження свердловинної штангової насосної установки під час її пуску.

Authors: Kiriia Ruslan , Dziuba Serhii , Mostovyi Borys
Published: March 2020

A mathematical model of the functioning of an accumulating bunker operating in the simplest transport system “conveyor-bunker-conveyor” has been developed. It was assumed thus, that time domains of outages and work of the above- and under-bunker conveyer lines are distributed on exponential laws. Based on the theory of two-phase Markov processes, a system of Kolmogorov equations is obtained with respect to the probabilities of finding the “conveyor-bunker-conveyor” system in various states. As a result of solving this system of equations, the dependence of the average carrying capacity of the system “conveyor-bunker-conveyor” on the volume of the bunker and the average cargo flow entering and unloading from the bunker is obtained. Based on the obtained dependence, the maximum volume of the accumulating bunker was determined at which the carrying capacity of the system “conveyor-bunker-conveyor” practically does not increase with increasing hopper volume.

Published: March 2020

The tasks of monitoring the state of complex technical objects are solved by evaluating and comparing experimental measurements. A new discrete analogue of the Smirnov-Cramer-von Mises criterion and a new discrete analogue of the Anderson criterion are proposed. Computational experiments have been carried out confirming the hypothesis that discrete models of the probability distribution function and the proposed discrete mean square of the difference in information content do not differ from the Anderson criterion and the Smirnov-Cramer-von Mises criterion, but it is much simpler in practical applications in the verification of statistical hypotheses homogeneity of short samples of experimental measurements.
The Influence of Locality on Migration: a Comparative Study of Britain and Sweden in the Nineteenth Century
Authors: Pooley Colin G.
Published: March 2020

This paper uses migration data for Britain and Sweden to critically examine the contention that locality or place influenced migration patterns and processes in the nineteenth century. Despite their very different geographies patterns of migration in Britain and Sweden in the nineteenth century were remarkably similar. Any differences can be accounted for by limitations in the available data. It is argued that at the national level geography had little impact on migration, but that at the local level most people in both countries were tied closely to particular localities. However, it is suggested that this is not primarily due to the specific characteristics of a place but, rather, can be attributed to the ties to family, friends and community which, while being situated in a place, are not produced by it. Finally, it is suggested that further comparative studies of demographic processes can aid the interpretation of local and regional population studies.
The Landholding Structure of a Northern Manor: Troutbeck, c. 1250–1800
Authors: Healey Jonathan
Published: March 2020

Troutbeck in the Lake District has a long run of landholding records, dating from the village's first appearance in the thirteenth century until modern times. This article uses these to recreate the nature of landholding across a broad span of history from the high Middle Ages to the end of the eighteenth century. It finds that numbers of customary landholders continued to grow despite the recurrent disasters of plague, famine and war in the fourteenth century, and showed growth again between the fifteenth and sixteenth centuries. The seventeenth century then brought two major changes: there were a growing number of subtenants up until the 1620s. Then, after old restrictions on the parcelling of tenements were lifted in the 1670s, landholdings started to fragment, and a group of small customary landholders developed and survived into the eighteenth century.
Railway Villages in South East Monmouthshire 1850-1965: a Community Perspective
Authors: Gant Robert
Published: March 2020

This study blends evidence from historical archives with findings from a household survey to explore differences in the impact of developments in the railway industry on the physical growth and changing social profiles of three neighbouring villages in south east Monmouthshire during the period 1850–1965. Within the framework of the community studies tradition, and conceptualisation of the railway village, this article differentiates local outcomes in employment and social profile generated by the construction of the Severn Tunnel and placement of associated infrastructure. The scene is set by examining phases in the local development of the railway industry, housing provision and related population trends. A critical overview of the principal data sources follows. This leads to an evaluation of the concept of 'community', aspects of which are illustrated from village case histories predicated on the selected themes of social segregation, assimilation, community anchorage and household persistence.
Unmarried Mothers and the New Poor Law in Hertfordshire
Authors: Williams Samantha
Published: March 2020

Under the old poor law mothers and fathers shared responsibility for their illegitimate children: fathers were expected to provide financial maintenance and mothers to care for and rear them. The new poor law sought to shift all responsibility on to mothers. This article focuses upon the impact of the new legislation upon poor women and their children and their interactions with poor law guardians. Using data drawn from applications to guardians and workhouse records for Hertford and Hatfield poor law unions this study analyses the welfare provision offered to unmarried mothers and their infants. The article considers all forms of assistance but with a particular focus on lying-in provision in the workhouse.
Cottage and Squatter Settlement and Encroachment on Common Waste in the Sixteenth and Seventeenth Centuries: Some Evidence from Shropshire
Authors: Bowen James P.
Published: March 2020

This article examines the local impact of cottage building on common wasteland in the wood-pasture countryside of the county of Shropshire in the sixteenth and seventeenth centuries. Based on the study of written documentary records, contemporary accounts and original maps, it examines the process of cottage building on commons in both rural agrarian and industrial contexts, exploring case studies of cottage settlement in a range of localities within Shropshire including forest, heathland, woodland and wetland areas. It outlines the character of the cottage economy and considers the regulation of cottages in relation to statute law concerning cottage building, poor relief and vagrancy. It complements the existing body of local and regional studies of cottage building, providing insight into the everyday lives of cottagers who built their cottages and encroached on common land, relying on commons access for their survival. Despite the informal existence of cottages and the fragile lives of those who inhabited them, it argues that it is possible to recover a picture of the impact of cottage settlement at a local level, and its significance as part of the development of the landscape.
Workhouse Populations of the Preston Union, 1841–61
Authors: Darwen Lewis
Published: March 2020

The census enumerators' books (CEBs) have provided fertile ground for studies of workhouse populations in recent years, though it has been acknowledged that work remains to be done on different regions and periods to develop our understanding of these institutions and the paupers who resided therein. This article will examine the indoor pauper populations of the Preston union, in Lancashire, over three census years from 1841. The region, which is notable for a protracted campaign of resistance to the New Poor Law and its associated workhouse system, has been previously neglected in studies of workhouse populations focusing on the decades immediately after the Poor Law Amendment Act of 1834. It will be shown that the profile of the union's workhouse populations broadly mirrors those found elsewhere at the aggregate level, but that important variations reflected local and central policy. A high concentration of able-bodied paupers—in particular—seems to indicate ideas governing local policy which were not carried out elsewhere.
'Indeed a health resort'? Mortality at the Leamington Provident Dispensary, 1869–1913
Authors: Wilmot John
Published: March 2020

Between about 1870 and 1914, persisting high levels of premature mortality from infectious diseases in the British population gave way to a pattern of deaths at later ages from degenerative, often chronic, conditions. The causes of this mortality transition have created much debate and have been attributed to the general effects of prosperity and the impact of organised preventive measures. Local evidence about such changes comes largely from industrial cities and generally fails to reflect the experience of smaller towns. This study uses the Leamington Provident Dispensary which published annual reports from 1869 to 1913, including tabulated causes of death. This group of working people, numbering 3,773 on average, formed about one-sixth of the borough population. Deaths from infectious conditions fell over time, while mortality from strokes and heart disease increased. Tuberculosis caused fewer deaths but continued to cause much chronic illness. Many of the local changes can be related to local sanitary and housing improvement, as well as to education in hygiene and infant feeding.

Excess usage of water than it is actually needed and water theft are the major issues leading to water scarcity nowadays. Some people draw more water by using motor pump. Whenever they use motor pump, or they open the valve to the maximum, the flow rate will be increased. Hence in the proposed system, measurement of flow rate plays a vital role. Water monitoring and theft prevention system are employed which records the flow rate and thereby providing notification about the theft and excess usage of water. In the proposed system, each consumer end is provided with a water flow monitoring system which consists of a flow sensor to measure the flow rate and an arduino controller for recording the flow rate. The flow rate value will be sent to the water distribution station using GSM. The flow rate is fixed by the central water distribution station, so that each consumer end will be receiving an equal quantity of water. Solenoid valve is attached in the Pipeline so that the flow rate can be varied by adjusting the valve position. The valve position, time of supply and the flow rate will be controlled by the central water distribution system. The GSM MODEM is initiated by the ON/OFF switch which is controlled by the arduino.
