Description
Известен способ выплавки стали, легированной хромом, никелем, титаном, по которому дл улучшени качества стали перед выпуском металла в нее ввод т титан, алюминий или другие сильные раскислители.A known method of smelting steel alloyed with chromium, nickel, titanium, according to which, to improve the quality of steel, titanium, aluminum or other strong deoxidizers are introduced into it before the metal is released.
По предлагаемому способу дл получени высо.ких .пластических свойств стали после дачи силикокальци в металл ввод т 0,2- 0,3 кг/т ферроборала, и плавку выдерживают в печи не менее 10 мин.According to the proposed method, to obtain high plastic properties of steel, after giving silicocalcium, 0.2-0.3 kg / ton of ferroborel is introduced into the metal, and the smelting is held in a furnace for at least 10 minutes.
Такое сочетание силикокальци и ферробонемета л ичecкиeThis combination of silicocalcium and ferrobonemets is medicinal.
рала уменьшает мелкие включени на границе зерен.rala reduces fine inclusions at the grain boundary.
Предмет изобретени Subject invention
Способ выплавки стали со скачиванием рафинировочного шлака и предварительным раскислением металла в печи силикокальцием, отличающийс тем, что, с целью увеличени пластических свойств стали, после дачи силикокальци в металл ввод т ферроборал в количестве 0,2-0,3 кг/т, и металл выдерл ивают в печи не менее 10 мин.The method of steelmaking with the download of refining slag and preliminary deoxidation of the metal in the furnace with silicocalcium, characterized in that, in order to increase the plastic properties of the steel, after giving silicocalcium, ferroboral in the amount of 0.2-0.3 kg / t is introduced into the metal Remove in the oven for at least 10 minutes.
