Abstract: FIELD: ferrous metallurgy. SUBSTANCE: method includes charging of iron charge, its heating and melting, finishing of liquid metal to attain required characteristics, and its blowing with neutral or inert gas by means of multinozzle blowing devices located in porous refractory layer of hearth. Liquid metal is blown by zones which are distributed along furnace longitudinal axis. Neutral or inert gas is supplied to each zone from blowing devices provided with at least 30 nozzles with diameter from 1.0 to 3.0 mm and gas pressure of 1-6 atm. Neutral or inert gas is passed with its distribution over zone surface through layer of porous refractory material with 2-10 mm fraction and thickness equalling 0.5-0.8 of total thickness of hearth to ensure specific density of blowing in each zone within range of 2.0-11.5 cu. m/h per 1 sq.m of its surface. Total intensity of blowing of liquid metal with neutral or inert gas is maintained within ranges ensuring efficient heat-mass transfer of liquid metal layers. Consumption of neutral or inert gas is varied from 0.09 to 0.45 cu.m per unit of thermal capacity of fuel flame as heat duty in furnace rises. EFFECT: higher productivity of steel melting process with provision of high quality parameters of steel, higher operating reliability of blowing devices. 5 cl, 3 dwg, 1 ex

Title: Method of sewage purification from phenol
Inventor: KHANKHASAEVA S TS
IPC: C02F101/34
Filed: 2000-04-28
Granted: 2001-10-10
Abstract: FIELD: purification of natural and circulating water, and sewage. SUBSTANCE: sewage is treated with hydrogen peroxide in the presence of Fe-montmoryllonite catalyst at hydrogen peroxide to phenol ratio of 7.5:1 which is 55% of desired stoichiometric amount. Ferric ions found on montmoryllonite surface by ionic exchange followed by calcination cause catalytic decomposition of hydrogen peroxide to form hydroxyl radicals which are potent oxidizers capable of destructing organic compounds, more particularly, phenols. Method makes purification process less durable, reduces specific consumption of oxidizer and retains high degree of purification of water from phenol. EFFECT: higher efficiency. 2 cl, 3 ex

Abstract: Изобретение относится к механическим испытаниям и предназначено для определения разрушающей нагрузки в элементах строительных и машиностроительных конструкций. Способ определения несущей способности пластинок переменного сечения с помощью их моделей заключается в изготовлении геометрически подобной натурной пластинке первой модели из винипласта, края которой закреплены в соответствии с заданными граничными условиями натурной пластинки, нагружении первой модели постепенно возрастающей нагрузкой, подобной действующей на натурную пластинку, до четкой визуализации зоны распространения пластических деформаций. Затем из того же материала, что и натурная пластинка, изготавливают вторую модель, форма которой геометрически подобна выявленной на первой модели зоне распространения пластических деформаций, жестко закрепляют вторую модель вдоль ее криволинейного края, а по остальным сторонам вторую модель закрепляют в соответствии с заданными граничными условиями натурной пластинки. Вторую модель нагружают и при этом определяют нагрузку, при которой происходит разрушение второй модели, по величине этой нагрузки расчетным путем с учетом выбранного масштабного коэффициента определяют несущую способность исследуемой натурной пластинки. Изобретение направлено на снижение трудоемкости изготовления пластинки-модели при сложном законе изменения толщины натурной конструкции. 2 ил.
