減少排除堿金屬不良影響采用低硫、低堿的鐵礦石燒結(jié)，合理配礦，減少人爐堿負(fù)荷。適當(dāng)增加燒結(jié)礦中MgO的含量，提高燒結(jié)礦強(qiáng)度，高M(jìn)gO燒結(jié)礦的軟化開始溫度比高堿度燒結(jié)礦高70-140℃;并且軟化溫度區(qū)間窄，低溫還原粉化率低，有利于高爐改善透氣性。在燒結(jié)過程中加人CaC12對(duì)燒結(jié)礦進(jìn)行氯化脫堿。CaC12既有利于提高燒結(jié)礦強(qiáng)度，又能與堿金屬反應(yīng)生成KCl和NaCl而形成蒸汽隨燒結(jié)廢氣排出。

從鐵水預(yù)處理開始，其中包括脫硫、脫硅，到連鑄中間包處理。要求降低鋼水有害雜質(zhì)的允許濃度，對(duì)于達(dá)到工藝性、塑性、韌性、耐寒性、耐總體和局部腐蝕及達(dá)到其他使用特性，顯得越來越重要。到目前為止，鋼的大規(guī)模生產(chǎn)中，許多雜質(zhì)達(dá)到的含量，與太陽能電池用半導(dǎo)體硅的生產(chǎn)中雜質(zhì)含量的允許范圍已幾乎可比。在兩種條件下一些元素的允許濃度為極少數(shù)到幾十ppm。鐵水脫硫是能極大降低鋼水硫含量的有效手段。正是在這種情況下，良好脫氧的金屬和渣相創(chuàng)造了脫硫有利條件。
