Изобретение относитс к металлургии, а именно к получению стали в электродуговых печах.FIELD OF THE INVENTION The invention relates to metallurgy, in particular to the production of steel in electric arc furnaces.
Известен способ выплавки стали, заключающийс в присадке перед окислительным периодом на шлак ванадиевого шлака и известн ка в количествах, соответственно 15- 16 кг и 5-6 кг на тонну металлозавалки. При этом указанные материалы ввод т в печь в два приема в течение 3-5 мин.There is a known method of steelmaking, which consists in addition to the oxidation period of slag of vanadium slag and limestone in quantities of 15-16 kg and 5-6 kg, respectively, per ton of metal dumping. At the same time, these materials are introduced into the furnace in two steps within 3-5 minutes.
Недостатком известного способа вл етс потер титана, содержащегос в виде окислов в ванадиевом шлаке.The disadvantage of this method is the loss of titanium contained in the form of oxides in vanadium slag.
С целью восстановлени титана из ванадиевого шлака по предлагаемому способу перед окислительным периодом на жидкоподвижный шлак ввод т алюминий или алюминиевую крошку из расчета 0,5-0,7 кг на тонну металлозавалки. Затем дают в два приема в интервале 3-5 мип вападиевый шлак и известн к в количестве соответственно 15-16 и 5-6 кг на тонну металлозавалки. При этом происходит процесс восстановлени титана из окислов. Шлак окислительного периода в процессе легировани не скачивают.In order to reduce titanium from vanadium slag by the proposed method, before the oxidation period, aluminum or aluminum crumb is added to the liquid slag at the rate of 0.5-0.7 kg per ton of metal slag. Then it is given in two steps in the range of 3-5 mip of wapadium slag and limestone in an amount of 15-16 and 5-6 kg, respectively, per ton of metal dumping. When this occurs, the process of reducing titanium from oxides. The slag of the oxidation period is not downloaded during the doping process.
После проведени указанных операций плавку ведут обычным методом.After performing these operations, smelting is carried out in the usual manner.

Способ выплавки стали путем введени ванадиевого П1лака в количестве 15-16 кг и известн ка в количестве 5-6 кг па тонну металлозавалки в два приема в течение 3- 5 мин, отличающийс тем, что, с целью восстановлени титана из ванадиевого шлака, перед окислительным периодом на жидкоподвижный шлак ввод т алюминий в количестве 0,5-0,7 кг па тонну металлозавалки.The method of steelmaking by introducing P1lak vanadium in an amount of 15-16 kg and limestone in an amount of 5-6 kg a ton of metal dumping in two steps for 3-5 minutes, characterized in that, in order to reduce titanium from vanadium slag, before oxidizing a period of 0.5–0.7 kg of aluminum is added to the molten slag per a ton of metal dumping.
