Известен способ легировани стали ванадием нутем присадки его в КОБШ после ввода легирующих добавок и раскислителей.There is a known method for the alloying of steel with vanadium by adding it to the Cobh after adding the alloying additives and deoxidizing agents.
Дель изобретени - улучшение раскисленности металла и расходов ферросплавов .The invention of the invention is the improvement of metal deoxidation and the consumption of ferroalloys.
Это достигаетс тем, что силикованадий присаживают в печь после удалени окислительного шлака на зеркало металла. Перед присадкой сплава металл предварительно раскисл ют ферросилицием до содержани кремни ОДО-0,. После ввода силикованади навод т новый восстановительный шлак.This is achieved by the fact that the silicovanadium is placed in the furnace after the oxidative slag is removed on the metal mirror. Before alloying, the metal is preliminarily deoxidized with ferrosilicon to the content of silicon ODO-0 ,. After the introduction of the silicovanadi, a new reducing slag is induced.
После проведени окислительного периода удал ют окислительный шлак и на зеркало металла присаживают ферросилиций из расчета на 0,10-0,20% кремни , а также ферромарганец . Затем присаживают силикованаднй в необходимом количестве и после этого навод т новый восстановительный шлак. ВAfter the oxidation period has been carried out, the oxidative slag is removed and ferrosilicon is deposited on the metal mirror at the rate of 0.10-0.20% silicon, as well as ferromanganese. Then, silicon silicate is applied in the required amount and after this a new reducing slag is introduced. AT

дальнейшем плавку провод т обычным образом .further melting is carried out in the usual manner.
Предлагаемый способ легировани стали ванадием позвол ет уменьшить расход ферросплавов , за счет чего себестоимость 1 т стали марки 40ХФА снижаетс на 0,Уб руб.The proposed method of alloying steel with vanadium reduces the consumption of ferroalloys, due to which the cost of 1 ton of 40HFA steel is reduced by 0, U RUR.
Предмет изобретени Subject invention
Способ легировани стали ванадием введением в расплав силикованади , отличаюШ .ИЙСЯ тем, что, с целью улучшени раскисленности металла и снижени расхода ферросплавов , силикованадий присаживают в печь после удалени окислительного шлака на зеркало металла, предварительно раскисленного ферросилицием до содержани кремни 0,10- 0,20%, а после ввода силикованади навод т новый восстановительный шлак.The method of alloying steel with vanadium by introducing silicate bathing into the melt, which is characterized by the fact that, in order to improve the metal deoxidation and reduce the consumption of ferroalloys, silicon oxide is placed in the furnace after removing the oxidizing slag on the metal mirror, previously deoxidized with ferrosilicon to contain 0.10-0 silicon, 20%, and after the introduction of silicovadi, a new reducing slag is induced.
