冶金石灰是炼钢用量最大的一种辅助原材料。氧气顶吹转炉对石灰有特殊的要求,就是活性度高,国外称它为软烧石灰。它的出现很快引起各国转炉工作者的关注。德蒂森公司在总结近20年转炉炼钢技术发展时,提到了7项重要技术,其中之一就是活性石灰的应用。在日本有些冶金工作者则认为,没有活性石灰,也就没有今天的转炉炼钢水平。这是因为转炉冶炼时间很短,要求石灰在十几分钟内就完成熔解和反应,即快速成
Metallurgical lime is the largest amount of steel used as an auxiliary raw material. Oxygen top converter has special requirements for lime, is highly active, foreign call it soft-burning lime. Its emergence soon attracted the attention of converter workers in various countries. In summarizing the development of converter steelmaking technology in the past 20 years, Dexisen mentioned 7 important technologies, one of which is the application of activated lime. Some metallurgists in Japan believe that there is no active lime, there is no today’s converter steelmaking level. This is because the converter smelting time is very short, requiring lime to complete the melting and reaction within ten minutes, that is, rapid into
