Title: Method for producing stainless steel
Inventor: SAKURATANI TOSHIKAZU
IPC: C21C1/02
Filed: 1989-03-07
Abstract: PURPOSE:To stably produce a stainless steel at a low cost by adding carbonaceous material and chromium-containing material into molten iron, executing smelting reduction with oxidized gas and after that, adding desulfurizing agent and executing decarbonization-refining to the desulfurized molten iron with the oxidizing gas in a decarbonizing furnace. CONSTITUTION:The molten iron is charged into a top and bottom blowing converter and the chromium-containing material of chromium ore, etc., and the carbonaceous material are added and oxygen is supplied. By these materials, the smelting reduction is executed to the chromium oxide. Then, the molten iron, which has the composition contg. about 10-20wt.% Cr and about 5% C and reaches to about 1500-1600 deg.C, is tapped off. The desulfurizing agent of CaO, etc., is added to this molten iron to execute desulfurization. Successively, this molten iron is charged into the decarbonizing furnace and the oxygen is supplied, if necessary while charging coolant, such as scrap, to execute the decarbonization-refining. Then, after steel-tapping from the decarbonizing furnace, it is desirable to recover Cr in slag in such a manner that the slag in the decarbonizing furnace is taken out and used to the smelting reduction process or a part of the slag is caused to remain in the decarbonizing furnace and used to the decarbonization-refining in the next heat. By this method, the stainless steel is stably produced at a low cost without eroding refractory in the decarbonizing furnace.

Title: Deciding method of rough working process
IPC: B23Q15/00
Filed: 1992-03-12
Abstract: PURPOSE:To reduce run-out of a work so as to improve working accuracy, concerning a rough working process deciding method. CONSTITUTION:At first, a rough working territory is decided from the form of raw material and the form of the part of a work (S1). The sort of an element is discriminated from the form constituting element on the end face side of the work (S5), and if it is an increase element, an element check flag is set (S9). If the form constituting element is a decrease element, whether an element check flag is set or not is discriminated (S6), and if it is set, the rough working territory is divided and a subsidiary rough working territory is decided (S7). Hereafter, a final subsidiary rough working territory is decided (S10). By preparing a working program in order from the subsidiary rough working territory on the end face side of the work and working, the weight ratio on the end face side of the work becomes small, and hence run-out of the work is reduced so as to improve working accuracy.
