呼倫貝爾高鐵砂
高鐵砂,由于鎂砂(sha)和(he)鐵(tie)(tie)粉混不勻(yun),燒(shao)(shao)結(jie)性(xing)能和(he)使用(yong)(yong)效(xiao)果均不佳,將(jiang)鎂砂(sha)粉和(he)鐵(tie)(tie)磷(lin)按比例相(xiang)配共同(tong)煅燒(shao)(shao)而后再(zai)用(yong)(yong)于補爐(lu),明顯(xian)改善了使用(yong)(yong)性(xing)能,本廠生產的(de)高(gao)(gao)鐵(tie)(tie)砂(sha)HMF68A提(ti)高(gao)(gao)了CaO的(de)含(han)量,它(ta)在砂(sha)中(zhong)(zhong)(zhong)主要以(yi)2CaO.Fe2O3(C2F)型存在,在高(gao)(gao)溫下C2F中(zhong)(zhong)(zhong)Fe2O3固熔(rong)到方鎂石(shi)中(zhong)(zhong)(zhong),提(ti)高(gao)(gao)了鎂砂(sha)晶間c/s,既(ji)易燒(shao)(shao)結(jie)又好用(yong)(yong),是現(xian)代電爐(lu)和(he)LD轉(zhuan)爐(lu)補襯、補底的(de)良好原料。
