廢鋼(gang)(gang)(gang)(gang)(gang)(gang)是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)爐(lu)(lu)(lu)煉(lian)鋼(gang)(gang)(gang)(gang)(gang)(gang)的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)主(zhu)(zhu)要(yao)(yao)(yao)原(yuan)料(liao)(liao)(liao)(liao)。 廢鋼(gang)(gang)(gang)(gang)(gang)(gang)的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)質(zhi)(zhi)量(liang)(liang)直接影響鋼(gang)(gang)(gang)(gang)(gang)(gang)材的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)質(zhi)(zhi)量(liang)(liang)、成(cheng)(cheng)本和(he)石(shi)(shi)(shi)墨(mo)(mo)(mo)(mo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)生(sheng)產(chan)(chan)率(lv)。 冶(ye)煉(lian)前的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)準備工(gong)(gong)作(zuo)(zuo) 爐(lu)(lu)(lu)料(liao)(liao)(liao)(liao)是(shi)(shi)石(shi)(shi)(shi)墨(mo)(mo)(mo)(mo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極煉(lian)鋼(gang)(gang)(gang)(gang)(gang)(gang)過程中不可(ke)缺少的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)部(bu)分(fen)。

合(he)理配(pei)料(liao)(liao)(liao)(liao)可(ke)縮(suo)短冶(ye)煉(lian)時(shi)間(jian)。 配(pei)料(liao)(liao)(liao)(liao)時(shi)應注(zhu)意以(yi)(yi)(yi)下幾點: 一是(shi)(shi)正確計算配(pei)料(liao)(liao)(liao)(liao)量(liang)(liang)，準確測(ce)量(liang)(liang)裝(zhuang)(zhuang)(zhuang)(zhuang)料(liao)(liao)(liao)(liao)量(liang)(liang)。 其(qi)次，裝(zhuang)(zhuang)(zhuang)(zhuang)藥(yao)(yao)量(liang)(liang)的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)大小應成(cheng)(cheng)比例，以(yi)(yi)(yi)達(da)到(dao)裝(zhuang)(zhuang)(zhuang)(zhuang)藥(yao)(yao)好(hao)、裝(zhuang)(zhuang)(zhuang)(zhuang)藥(yao)(yao)快的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)。
