為了提高渣中FeO的含量來脫Si，所以在精煉過程中加鐵礦石，在其過程中可能會(huì)伴隨有S的，但不需再進(jìn)行造渣去硫，而是在精煉結(jié)束出鎳鐵水的時(shí)候會(huì)洗渣降硫，使得精煉后的鎳鐵水硫含量降到了0.05%。KR脫硫精煉工藝KR脫硫攪拌法是鐵水脫硫工藝中常用的一種，與噴吹法脫硫相比，具有動(dòng)力學(xué)條件好、脫硫效率高、脫硫劑的使用量少、可控制性強(qiáng)等優(yōu)點(diǎn)，目前成為鐵水爐外脫硫方法中技術(shù)優(yōu)越，工藝成熟，成本較低的脫硫工藝，現(xiàn)已在各鋼廠中廣泛使用。

低氧鋼生產(chǎn)技術(shù)在鋼中氧含量過高，則角狀?yuàn)A雜物及宏觀夾雜物增多，易于發(fā)生脆性斷裂，而且非金屬夾雜物含量過多也影響鋼表面質(zhì)量。寶鋼主要針對(duì)IF鋼，開展了一系列旨在降低全氧含量，減少夾雜物和防止卷渣的研究，在生產(chǎn)中所采用的措施包括：采用擋渣出鋼，要求使鋼包渣層厚度70mm。鋼包渣改質(zhì)：出鋼時(shí)向鋼包表面加入改質(zhì)劑，降低渣的氧化性。控制RH中F[O]濃度和純脫氣時(shí)間。采用中間包純凈化技術(shù)。為了防止結(jié)晶器保護(hù)渣卷入，采用不易卷入的高粘度保護(hù)渣。
