萤石是转炉炼钢应用最普遍的助熔剂,它对石灰熔化和炉渣稀释有明显的作用,而且化渣速度快,用量少,但对炉衬侵蚀严重,造成环境污染,加上萤石资源有限,供应不足和价格昂贵等原因,多年来,国内外的冶金工作者一直在寻找萤石的代用材料。我们从1986年11月至1987年5月,在首钢试验厂6t Fluorite is the most commonly used flux in BOF steelmaking. It has a significant effect on melting lime and slagging, and it has the advantages of quick slagging speed and low dosage, but it causes serious erosion to the lining and causes environmental pollution. In addition, fluorite resources Limited, insufficient supply and expensive reasons, over the years, metallurgical workers at home and abroad have been looking for alternative materials fluorite. We from November 1986 to May 1987, at Shougang pilot plant 6t
