順義高鐵砂
高鐵砂,由于(yu)鎂砂和鐵(tie)(tie)粉混不勻,燒(shao)結性能和使用(yong)(yong)(yong)效果均不佳(jia),將鎂砂粉和鐵(tie)(tie)磷按比(bi)例相(xiang)配(pei)共同煅燒(shao)而后再用(yong)(yong)(yong)于(yu)補(bu)爐(lu),明顯改善了使用(yong)(yong)(yong)性能,本廠生產的高(gao)(gao)鐵(tie)(tie)砂HMF68A提(ti)高(gao)(gao)了CaO的含量,它在(zai)砂中(zhong)(zhong)主要以2CaO.Fe2O3(C2F)型存在(zai),在(zai)高(gao)(gao)溫(wen)下C2F中(zhong)(zhong)Fe2O3固(gu)熔到方鎂石中(zhong)(zhong),提(ti)高(gao)(gao)了鎂砂晶間c/s,既易燒(shao)結又好用(yong)(yong)(yong),是(shi)現(xian)代電爐(lu)和LD轉爐(lu)補(bu)襯、補(bu)底的良好原料。
