转炉副枪是六十年代末、七十年代初发展起来的一种比较重要的新技术。现根据一些国外有关资料,分五个方面综述如下。 一、副枪技术及其发展背景 氧气顶吹转炉炼钢自1952年奥地利林茨地方采用以来,迄今已经有廿多年的历史了。转炉钢在世界钢产量中所占的比重逐年增长。1965年为16.4％,1970年为40.8％,据国际钢铁协会1972年预计,1975年为50.0％,1980年将达59.0％。日本自1957年采用氧气顶吹转炉炼钢新工艺以来, Converter sublance is developed in the late sixties, early seventies a more important new technology. Now based on some relevant foreign information, summarized in five aspects as follows. First, the sub-gun technology and its development Background Oxygen blowing converter steelmaking since 1952 the Austrian Linz local adoption has so far been more than 20 years of history. The share of converter steel in world steel production has been increasing year by year. 16.4% in 1965 and 40.8% in 1970. According to the International Iron and Steel Institute’s estimation in 1972, it was 50.0% in 1975 and 59.0% in 1980. Since 1957, Japan has adopted oxygen top-blown converter steelmaking new technology,
