自貢高鐵砂
高(gao)鐵砂,由于(yu)鎂(mei)砂(sha)和(he)鐵(tie)粉(fen)混(hun)不勻(yun),燒結性(xing)能(neng)和(he)使用(yong)(yong)(yong)效果均不佳,將鎂(mei)砂(sha)粉(fen)和(he)鐵(tie)磷(lin)按比例相配共同煅燒而后再(zai)用(yong)(yong)(yong)于(yu)補(bu)(bu)爐,明顯改善了(le)使用(yong)(yong)(yong)性(xing)能(neng),本廠(chang)生產(chan)的高鐵(tie)砂(sha)HMF68A提高了(le)CaO的含(han)量,它在砂(sha)中(zhong)(zhong)(zhong)主要(yao)以2CaO.Fe2O3(C2F)型(xing)存(cun)在,在高溫下C2F中(zhong)(zhong)(zhong)Fe2O3固熔到方鎂(mei)石中(zhong)(zhong)(zhong),提高了(le)鎂(mei)砂(sha)晶間(jian)c/s,既易燒結又好(hao)用(yong)(yong)(yong),是現代電爐和(he)LD轉(zhuan)爐補(bu)(bu)襯、補(bu)(bu)底的良好(hao)原料。
