懷柔高鐵砂
高鐵砂,由(you)于鎂砂和(he)鐵(tie)(tie)粉(fen)混不(bu)勻,燒(shao)結性能和(he)使(shi)用(yong)(yong)效果均不(bu)佳,將鎂砂粉(fen)和(he)鐵(tie)(tie)磷按比(bi)例相配共(gong)同煅燒(shao)而后再用(yong)(yong)于補(bu)(bu)爐,明顯改善了使(shi)用(yong)(yong)性能,本廠生產的高(gao)鐵(tie)(tie)砂HMF68A提高(gao)了CaO的含量(liang),它在(zai)砂中主要(yao)以2CaO.Fe2O3(C2F)型存在(zai),在(zai)高(gao)溫下C2F中Fe2O3固熔(rong)到方鎂石中,提高(gao)了鎂砂晶(jing)間c/s,既易燒(shao)結又好用(yong)(yong),是(shi)現代電爐和(he)LD轉爐補(bu)(bu)襯、補(bu)(bu)底的良好原料(liao)。
