一、前言 1980年以来,武钢和武院合作对氧气转炉复合吹炼技术进行研制。1983年底,武院按武钢要求的“先简易、后完善”的方针,设计的复吹供气系统,先后把三座顶吹转炉改造成顶底复合吹炼转炉并投入生产。自投产以来,已取得了良好的经济效益。然而,就前一阶段的技术、装备水平和效果而言,还未达到国外先进水平,其主要差距有三: ①底吹供气强度低,一般为0.02～0.03标米~3/分·吨,未达到复吹转炉应有的
I. Introduction Since 1980, Wuhan Iron and Steel and Wuyuan cooperation in oxygen converter composite blowing technology developed. By the end of 1983, according to the policy of “simple and perfect after first” proposed by WISCO, Wuxun designed the double blow air supply system and successively transformed the three top blow converters into the top and bottom composite blower converters and put them into production. Since put into production, has achieved good economic returns. However, as far as the technical level, equipment level and effect of the previous stage are concerned, the advanced level in the world has not yet been reached. The main differences are as follows: ① The intensity of bottom blowing gas supply is low, generally 0.02 to 0.03 m 3 / min · ton, Fundamental blowing converter should not be met
