徐匯高鐵砂
高鐵(tie)砂,由于鎂(mei)砂和鐵粉(fen)混不(bu)勻,燒(shao)結性能和使(shi)用(yong)(yong)效果均不(bu)佳,將(jiang)鎂(mei)砂粉(fen)和鐵磷按(an)比(bi)例相配(pei)共同煅燒(shao)而后(hou)再用(yong)(yong)于補(bu)爐(lu),明顯改善了使(shi)用(yong)(yong)性能,本廠生產的高(gao)(gao)(gao)(gao)鐵砂HMF68A提高(gao)(gao)(gao)(gao)了CaO的含量,它在砂中(zhong)主要(yao)以2CaO.Fe2O3(C2F)型存(cun)在,在高(gao)(gao)(gao)(gao)溫下C2F中(zhong)Fe2O3固熔(rong)到(dao)方鎂(mei)石中(zhong),提高(gao)(gao)(gao)(gao)了鎂(mei)砂晶(jing)間c/s,既(ji)易燒(shao)結又好(hao)用(yong)(yong),是現(xian)代電爐(lu)和LD轉爐(lu)補(bu)襯、補(bu)底的良好(hao)原料(liao)。
