一、前言不锈钢工业性生产是从1920年开始的。在1960年普遍采用氧气炼钢技术以后,使不锈钢产量获得很大发展。近20年来世界不锈钢产量已增加了四倍。从1970年起日本的不锈钢产量超过美国而居世界第一位。冶炼不锈钢的方法除电炉和转炉直接冶炼外,由电炉或转炉供应半钢,采用炉外精炼方法生产(如 VOD 法,VODC 法,RH—OB法,AOD 法和 CLU 法),目前世界上应用 AOD法冶炼不锈钢的产量占75%以上。
First, the preface Stainless steel industrial production started from 1920. After the general adoption of oxygen steelmaking technology in 1960, the stainless steel production has greatly developed. The world stainless steel output has tripled in the past 20 years. Japan’s stainless steel production surpassed that of the United States in 1970 and ranks first in the world. In addition to the smelting of stainless steel smelting furnace and converter smelting, the supply of semi-steel from the electric furnace or converter, the furnace refining method (such as VOD method, VODC method, RH-OB method, AOD method and CLU method), the current world application AOD smelting stainless steel production accounted for more than 75%.
