当前世界上普遍采用优质活性石灰炼钢,可以缩短冶炼时间,提高炉龄,降低消耗,提高钢的质量和节约能源,具有重大的经济意义。本文就近年来活性石灰的生产和应用作一简介。1.氯气转炉对石灰质量的要求1·1 石灰活性度石灰的活性度是指它在熔渣中与其他物质的反应能力,用石灰在熔渣中的熔化速度来表示。可用石灰与水的反应速度(取石灰水活性)来表示。测定
Currently, the world wide use of high quality active lime steelmaking can shorten the smelting time, improve the furnace age, reduce the consumption, improve the quality of the steel and save energy, which is of great economic significance. In this paper, active lime production and application in recent years for a brief introduction. 1. Chlorine converter requirements for lime quality 1.1 Lime activity Lime activity refers to its ability to react with other substances in the slag, with the melting rate of lime in the slag to represent. Available lime and water reaction rate (lime water activity) to represent. Determination
