摘要
钢中夹杂物去除的主要环节为夹杂物的长大、上浮和分离。钢中夹杂物去除技术的主要进展有:气体搅拌-钢包吹氩、中间包气幕挡墙和RH-NK-RERM法;电磁净化-钢包电磁搅拌、中间包离心分离和结晶器电磁制动;渣洗技术;过滤器技术。文中分析了各种夹杂物去除技术的冶金功能,将不同夹杂物去除技术进行合理组合,实现多功能精炼,可取得最佳冶金效果。
Main links for removal of inclusions in liquid steel are inclusion growth, floating and separating. The key progress on technique for removal of inclusion in steel is gas stirring-ladle argon blowing, gas shielding weir and dam in tundish, RH-NK-RERM method; electromagnetic cleaning-ladle electromagnetic stirring, tundish centrifugal separating and mold electromagnetic braking; slag washing and filter technique. The metallurgy functions of each technique for removal of inclusions in steel are analyzed in this article. It is available to get optimum metallurgical effect by reasonably combined different technique for removal of inclusions to carry out multi-function refining.
