国外不锈钢向民用方面大量渗透,其主要原因之一在于不锈钢冶炼工艺有了显著地发展,技术上日益革新,尤其是日本,近十年来引进了AOD、VOD等技术,不锈钢生产技术发展很快,冶炼采用的原料以使用高碳铬铁和高碳镍铁为主,从原料方面开创了生产不锈钢的新局面。江苏省在引进新技术的同时,如何利用现有电炉,轧机和热处理设备,进行必要的配套,也可生产出价廉物美的民用不锈钢,这是当前江苏省冶金工业适应新形势需要的一个课题。本文对含镍量为18％的铁素体不锈钢的热轧工艺进行探讨,以使该钢种冶炼,热加工、冷加工及热处理完善,便于早日投入市
One of the main reasons for the large-scale infiltration of stainless steel from foreign countries into civilian areas is that the stainless steel smelting process has been significantly developed and its technology has been revolutionized. Japan, in particular, introduced technologies such as AOD and VOD in the past decade. The stainless steel production technology has developed rapidly, The smelting raw materials to use high-carbon ferrochrome and high-carbon ferronickel-based, from the raw materials to create a new situation in the production of stainless steel. Jiangsu Province, introducing new technologies, how to use the existing electric furnace, rolling mill and heat treatment equipment, to carry out the necessary facilities, but also produce inexpensive civilian stainless steel, which is the current Jiangsu Province, the metallurgical industry to adapt to the new situation needs a subject . In this paper, the hot rolling process of ferritic stainless steel with 18% nickel content is discussed in order to improve the smelting, hot working, cold working and heat treatment of the steel so that it can be put into the market as soon as possible
