Published: January 2019

One of the important reasons for the downtime of ball rolling mills is replacement of rolls due to their wear and tear. The degree and zones of critical wear of ball rolling rolls are investigated in the article, where the greatest wear is observed over the flanges in zone of billet capture. Conditions necessary to capture the blank and to perform rolling process are analytically determined. Variable frequency method of roll rotations is proposed as a progressive technology for blank supply. The results of tests for its variations in accordance with linear and quadratic law are presented. Known formulas determining average strain rate at rolls rotational speed change are converted for linear and quadratic dependences. Experimental studies have been carried out in conditions of EVRAZ Nizhnetagilsky Metallurgical Plant ball rolling mills during rolling of 60mm ball made of Sh-3G steel. Experiments were performed for given parameters of manual change in rolls rotation speed at blank capture by rollers. The results have shown a significant effect of change in rotational speed on average specific pressure during blank capture. Evaluation of torque-time and average contact pressure for calculated and experimental data are presented. Empirical characteristics are also described at variable rotational speed of rolls according to linear and quadratic law. Acceptable convergence of results of calculated and empirical characteristics is determined. Engineering solution has been proposed for that task. It consists in installation of a thyristor converter. This solution allows reduction of rolls speed before blank capture. Also, this solution will increase frequency to the nominal value according to the given law after blank capture. As an obtained result, there is uniform distribution of average contact pressure over the entire length of the roll under different operating conditions of mill in automatic mode. Application of this technique will reduce wear degree of the rolling tool. At the same time, productivity of ball rolling mill will be maintained. Rolls consumption and number of rolls change will decrease due to rolls wear.

Effect of deformation along various directions against migrating boundary on migration rate of edge boundaries with <100> and <111> misorientation axes in nickel was studied by means of molecular dynamics method. Grain boundaries were created in U-shaped model. Force of boundary surface tension, arising from the boundary intension to minimize its energy, was the reason of directed movement of the boundary toward its area decrease. The force provoking migration and migration rate of the boundary remained constant throughout the entire movement of the boundary, gradually decreasing towards the end of computer experiment, which made it possible to measure migration rate quite simply. Effect of uniaxial deformation along the X, Y, Z axes on migration rate of the boundaries was considered. Uniaxial deformation in the model was set at beginning of the computer experiment by changing corresponding interatomic distances along one of the axes. Interactions of nickel atoms with each other were described with the aid of Cleri Rosato many-particle potential constructed in the framework of tight binding model. For the boundaries considered, dependences of migration rate on misorientation angle at temperature of 1700 K were obtained. It is shown that the high-angle <111> and <100> edge boundaries migrate approximately at the same rate, while mobility of low-angle boundaries differs significantly: low-angle <111> boundaries migrate about twice as fast as the <100> boundaries. It was found that in almost all cases, both at elastic compression and tension deformation, migration rate of considered boundaries was slowed down. An exception was the case of deformation along the <111> edge boundary axis. When compressing along the edge axis, <111> boundary migrated faster, while on the contrary, it was slower at tension. The obtained results testify to the fact that migration of edge boundaries is not due to diffusion processes, such as climbing of dislocations, single migrations of atoms, but, apparently, by collective atomic permutations: shifts, slides and splittings of grain boundary dislocations.

Published: January 2019

The article presents high-carbon hypereutectoid steel for production of hot rolling forged rolls. The steel contains 1.2 – 1.4 % of carbon, carbide forming alloying elements Cr, Mo, V and Nb improving wear resistance of the rolls, and Ni increasing hardening capacity. It has been found that steel of proposed composition provides ductility sufficient for hot deformation (forging) by moderate single compressions. Temperature range of ingot deformation has been detected: finite temperature deformation should not be below 900 °C, forging temperature – 1150 °C. According to its properties steel can be recommended for manufacturing solid-forged rolls and bandages for composite rolls of hot rolling from ingots of up to 10 tons weight.

Published: January 2019

Detailed investigation of mechanical, deformation and rheological properties of frozen soils is an actual issue, as they are basis of civil- engineering survey for underground constructions in permafrost holding more than 50% of the territory of Russia. The majority of modern software packages which calculate structures stability considering stress state of soils massive, demand knowledge of mechanical and rheological parameters defined by triaxial compression tests. The current article presents: estimation method of frozen soils rheological parameters by triaxial compression testing; required equipment and the research results. The samples of frozen soil 10 – 50 m depth from Kharasavey gas field were used as test material. Mostly they are presented by loam, clay and sand. The experiments were run at the range of temperature from −3°C to −6°C.. Triaxial compression testing was provided by the laboratory equipment which allows to run experiments in the mode of automatic load, maintenance and deformation processes registration. Test procedure of rheological parameters identification under conditions of long-term triaxial compression considered incremental load Stage duration was equal to 24 hours. The experiments were run until th specimen’s failure. As a result of the testing, mechanical, deformation and rheological parameters for frozen soils are defined at temperatures −3°C  −6°C. The achieved results can be interpreted in different models (Mohr-Coulomb, Drucker-Prager, Tresca etc.). The described experiments were carried out at LLC Gazprom Geotechnology for the design of underground drill cutting s storages in permafrost.

Authors: Shkrabets F. P. 
Published: January 2019

The increase in the capacity of cleaning and construction vehicles for highcapacity and energy-intensive mines calls for an increase in the supply voltage of cleaning and tunneling combines, as well as transport systems: from a voltage of 660 V switched to 1140 V, and now to 3300 V. This allows improving technical and economic indicators for clearing and access areas, as well as improving the reliability of local Power Supply Systems (PSS). However, this trend prevents the supply of underground electric networks with a voltage of 6 kV, in connection with which the problem arises of increasing the voltage of supply networks. To date, it has become possible to apply the 10 kV voltage to the operation, which is most acceptable for the use of electrical equipment for electrical networks and protection devices. Leading educational, research and design organizations were engaged in research on this issue. An analysis of the results of the research showed that switching to 10 kV voltage is justified and timely. At the same time, 35 kV voltage is not removed from the agenda, which is technically feasible and economically justified, but there are problems with the safety of its operation in underground workings, which requires appropriate refinement. This level of voltage will improve the quality of electricity.Conclusions: 1. Application of 35 kV voltage in the underground power supply system of coal and ore mines is advisable at a depth of more than 1000 m with a maximum load of at least 1000 kVA at the level of the stem cables.2. Application of 35 kV voltage in underground electrical networks will allow to significantly improve the quality indicators of voltage, reliability, and economy of the system due to the current unloading of the most important element of SES, such as stem cables.3. Analysis of the main parameters and characteristics of electrical mine electrical equipment gives reason to believe that it allows implementing a trend of 35 kV deep input to deep horizons of mines (mines) and placement of 35/6 kV substations on working horizons.

Authors: Bitskiy R. R. 
Published: January 2019

Technical progress is impossible without the creation of new devices, the quantitative and qualitative indicators of which radically differ from the known ones, which in turn requires new technologies and materials. In the creation of new materials, rare and rare-earth metals are increasingly used, the reserves of which are very limited. Therefore, the development and implementation of new methods of mining such metals are a timely and urgent task.Prospective methods of mining mineral deposits from volcanic gases are considered. The proposed model makes it possible to reveal the composition of volcanic gas, to experimentally prove its dynamic properties, to develop a model that allows one to trace the behavior of gas, on its basis to develop a principle scheme for extracting rare-earth elements (REE) and to present the hardwaretechnological scheme for obtaining REE from fumaroles (types of gas) in the form fumarolic metallurgical plant.On the basis of a model system with heavy metal solutions in a liquid, the possibility of studying the behavior of gas particles is shown. Such a model system is converted to volcanic gas and allows interpretation of the results for a fumarolic metallurgical unit (FMU) by determining the critical dimensions of the elements of such an installation (dome sizes, parameters of connecting hoses).

Published: January 2019

Aim.To compare adherence behavior patterns in patients with primary and recurrent myocardial infarction before hospital discharge.Methods.145 patients with myocardial infarction admitted to the Kemerovo Regional Clinical in the period from November to December 2016 were included in a single-centre, nonrandomized, prospective study. All the patients were interviewed using the original adherence questionnaire. All the patients were divided into 2 groups: patients with primary myocardial infarction (n = 74) and recurrent (n = 71) myocardial infarction.Results.Both, patients with primary and recurrent myocardial infarction, had low adherence to treatment and healthy lifestyle, poor disease awareness which appeared to be a signifcant factor worsening their long-term prognosis. Recurrent myocardial infarction was associated with increased readiness to adhere the treatment regimen more strictly (62%), but it was not accompanied by any improvements in patients’ awareness on the causes of the disease (36.6%), their health status (30.9%) and secondary prevention (63.3%). The great number of subjective factors affecting patients’ adherence to the long-term therapy prescribed by a healthcare professional requires the implementation of additional information management for patients with any type of myocardial infarction about the importance of subsequent therapy, special education programs, and group psychotherapy.Conclusion.Poor adherence in patients with any myocardial infarction to the prescribed therapy after discharge (less than 80%) requires a preventive use of educational and psychological programs improving medical and social awareness and readiness to adhere to treatment prescribed by the healthcare professional.

Published: January 2019

This
study was conducted to experimentally determine the effect of thermal screens
used for heat saving and overall heat consumption coefficient on heat loss in
greenhouses. The trial was established in three different lettuce greenhouses
with 150 m2 in floor size using different plastic covering materials
between January and April. Hot air vent heaters were used for heating. The heaters were positioned 30 cm above
ground level. The heating was done between 08.00 p.m. and 05.00 a.m. Plant
level and roof level as well as external temperature and relative humidity were
measured with data loggers. These measurements were used to statistically
calculate overall heat consumption coefficient based on wind speed. The results
demonstrate that thermal screens created a resistance against heat loss, thus
reducing heat losses. The effect of thermal screens on heat loss depending on
the wind speed was also determined. It was found out that heat saving ratios in
greenhouses varied between 8% to 22% under very low wind speeds and between 17%
- 36% under a wind speed of 4 m s-1.
