一、前言随着氧气炼钢的迅速发展,特别是氧气转炉炼钢的吹炼时间只有15～20min,因此要求石灰具有很高的溶解速度。普通石灰限制了转炉生产的发展。我国目前转炉炼钢,只有武钢、宝钢等少数炼钢厂使用优质活性石灰,而占全国转炉钢产量80%的转炉炼钢是使用竖窑生产的普通石灰。 First, the foreword With the rapid development of oxygen steelmaking, especially the oxygen converter steelmaking blowing time is only 15 ~ 20min, thus requiring lime has a high dissolution rate. Ordinary lime limits the development of converter production. China’s current converter steelmaking, only a small number of WISCO, Baosteel and other high-quality steelmaking active lime, and accounted for 80% of the country’s converter steel production is the use of shaft kiln production of ordinary lime.
