上海高鐵砂
高鐵砂,由于(yu)鎂(mei)(mei)砂和鐵粉混不(bu)勻(yun),燒結性能和使用(yong)(yong)(yong)效果均不(bu)佳,將鎂(mei)(mei)砂粉和鐵磷按比例(li)相配(pei)共(gong)同煅燒而后再用(yong)(yong)(yong)于(yu)補爐(lu),明顯改善了使用(yong)(yong)(yong)性能,本廠(chang)生產的高(gao)鐵砂HMF68A提(ti)(ti)高(gao)了CaO的含量,它在(zai)砂中(zhong)(zhong)主要以2CaO.Fe2O3(C2F)型(xing)存(cun)在(zai),在(zai)高(gao)溫(wen)下C2F中(zhong)(zhong)Fe2O3固熔到方鎂(mei)(mei)石中(zhong)(zhong),提(ti)(ti)高(gao)了鎂(mei)(mei)砂晶間c/s,既(ji)易燒結又好用(yong)(yong)(yong),是現代電爐(lu)和LD轉爐(lu)補襯、補底的良好原料。
