1.引言本文系作者作为日本铁钢协会访华代表团的一员访问中国金属学会所作报告的缩写。在选录并着重用图表说明的一些课题中,回顾了日本近十年来(炼钢)技术发展的背景。 2.LD(BOF)法和Q-BOP法的脱碳 Q-BOP法从1977年1月开始在川崎钢铁公司投入使用,而LD法现在在炼钢上最流行。图1示出这两种炼钢法吹炼终点的C-O关系。LD法的C-O曲线接近Pco≡
1. INTRODUCTION This article is the author of an interview with the China Institute of Metals as a member of the Japan Iron Steel Association’s delegation to China. In selecting and highlighting some of the topics charted, we review the background of Japan’s (ten-year) steelmaking technology. 2. Decarbonization of LD (BOF) method and Q-BOP method The Q-BOP method was put into operation at Kawasaki Iron & Steel Co. since January 1977 and the LD method is now the most popular in steelmaking. Figure 1 shows the C-O relationship between the two steelmaking blowing ends. The C-O curve of LD method is close to Pco≡
