Title: Method for denitrifying molten stainless steel
Inventor: TANAKA YUJI
IPC: C21C7/00
Filed: 1991-12-27
Abstract: PURPOSE:To provide a new denitrifying method of molten stainless steel without using the denitrification according to oxygen top-blowing vacuum-decarburization in a VOD furnace. CONSTITUTION:The molten raw stainless steel primarily decarburized in a steelmaking furnace is oxygen-top-blowing-decarburized and vacuum-decarburized in the VOD furnace to produce a low carbon or an ultra low carbon stainless steel. Successively, slag-making material of CaO and Al2O3 forming low m.p. slag is added by >=20kg/t of molten steel, and also Al is added and sol.Al in the molten steel is kept at least for 5min in >=0.7wt% concn. and thereafter, by top-blowing the oxygen, the sol.Al in the molten steel is oxidized and removed to the prescribed value. By this method, without lengthening the refining time in the VOD furnace, the low nitrogen stainless steel having the low carbon or the ultra low carbon can be produced in high productivity and at low cost.
