Granted: 1998-02-20
Abstract: FIELD: ferrous metallurgy. SUBSTANCE: method includes charging of coolants, pouring of vanadium-containing iron, ignition and blowing the melt with oxygen, portion addition of slag-forming materials, metal tapping into ladle, metal deoxidation, recarbonization and metal refining. Coolants are used in the form of metal scrap and/or metal wastes. Slag-forming materials are added in the course of blowing after ignition of melt by portions with weight ensuring optimal metal heating and slag formation. Metal is blown up to carbon content less than 0.07 wt.-%. Recarbonization of metal is effected with liquid vanadium iron whose amount is determined by carbon content in finished steel and calculated by formula Q = Vx(Cst/Ci), where Vx is liquid steel weight, t; Cst is carbon content in the required grade of steel, wt. -%; Ci is carbon content in iron, wt.-%. To prevent ejection of metal from ladle, introduced into vanadium intended for recarbonization, deoxidation and alloying may be 20-50% of strong deoxidizers required for heat. To optimize the heat balance, metal scrap and/or metal wastes are additionally heated by supplying carbon-containing fuel to scrap and/or metal wastes and its burning with oxygen. Carbon-containing fuel is used in the form of coke, bituminous coal, broken carbon lining and electrodes, oil, residual fuel oil, natural gas. Metal is refined on the FURNACE-LADLE unit. The method makes is possible to process vanadium iron in oxygen steel-making converters in monoprocess with use of scrap and/or metal wastes up to 30%. This results in reduction of heat duration, extended assortment of made steels, decreased consumption of flux and ferroalloys and production of naturally alloyed steel containing vanadium in the amount of 0.05-0.15 wt.-% with guaranteed level of mechanical properties and increased productivity of the complex as a whole.

Abstract: Способ предназначен для решения задач инженерной геофизики. Сущность способа состоит в следующем. Создается переменное магнитное поле последовательно на многих частотах. На каждой частоте выполняется измерение реальной и мнимой компонент вторичного магнитного поля двумя приемными датчиками, расположенными вдоль одной прямой с генераторной петлей. Сигнал прямого поля компенсируется путем применения двух встречно включенных приемных датчиков при условии, что на средней частоте рабочего диапазона отношение магнитного момента первого датчика к кубу расстояния от центра первого датчика до центра генераторной петли равно отношению этих же величин для второго датчика. Моменты приемных датчиков стабилизируются в интервале рабочих частот путем выбора толщины стенки цилиндрического ферритового сердечника каждого датчика, равной третьей части толщины скин-слоя электромагнитного поля в материале сердечника. Стабилизация моментов позволяет жестко зафиксировать положение датчиков относительно генераторной петли. 1 з.п. ф-лы, 1 ил.
