雅安高鐵砂
高(gao)鐵砂,由于(yu)鎂(mei)(mei)砂(sha)(sha)和鐵粉混不勻(yun),燒結性能和使(shi)用(yong)效果均不佳,將鎂(mei)(mei)砂(sha)(sha)粉和鐵磷(lin)按(an)比例(li)相配共(gong)同煅燒而后再用(yong)于(yu)補爐,明(ming)顯改善了使(shi)用(yong)性能,本(ben)廠生(sheng)產的高(gao)(gao)鐵砂(sha)(sha)HMF68A提高(gao)(gao)了CaO的含量(liang),它在砂(sha)(sha)中(zhong)(zhong)主(zhu)要以2CaO.Fe2O3(C2F)型存在,在高(gao)(gao)溫下(xia)C2F中(zhong)(zhong)Fe2O3固(gu)熔到方鎂(mei)(mei)石中(zhong)(zhong),提高(gao)(gao)了鎂(mei)(mei)砂(sha)(sha)晶間c/s,既易燒結又好用(yong),是現代電爐和LD轉爐補襯(chen)、補底的良好原料。
