金山高鐵砂
高鐵砂,由(you)于(yu)鎂砂和鐵粉(fen)混(hun)不(bu)勻,燒(shao)(shao)結性能(neng)和使(shi)用(yong)(yong)(yong)效(xiao)果均不(bu)佳(jia),將鎂砂粉(fen)和鐵磷按比例相配共同煅燒(shao)(shao)而(er)后再用(yong)(yong)(yong)于(yu)補(bu)爐,明顯改善了使(shi)用(yong)(yong)(yong)性能(neng),本廠(chang)生產的高鐵砂HMF68A提高了CaO的含量,它在砂中主(zhu)要(yao)以2CaO.Fe2O3(C2F)型存在,在高溫下(xia)C2F中Fe2O3固(gu)熔到方鎂石中,提高了鎂砂晶間c/s,既易燒(shao)(shao)結又好用(yong)(yong)(yong),是現代(dai)電爐和LD轉(zhuan)爐補(bu)襯、補(bu)底的良好原料(liao)。
