转炉留渣加双渣工艺是利用低温有利于脱磷反应的热力学基本原理，在同一座转炉中连续脱硅、脱磷、除渣和脱碳，酒钢采用该技术在同一座转炉中进行“留渣”加“双渣法”的少渣冶炼技术，大幅度降低了石灰、白云石等消耗，总渣量可降低25％～33％。
轉爐留渣加雙渣工藝是利用低溫有利于脫燐反應的熱力學基本原理，在同一座轉爐中連續脫硅、脫燐、除渣和脫碳，酒鋼採用該技術在同一座轉爐中進行“留渣”加“雙渣法”的少渣冶煉技術，大幅度降低瞭石灰、白雲石等消耗，總渣量可降低25％～33％。

Slag-remaining and double-slag converter steelmaking technology was based on thermodynamic principle of de-phosphorization reaction at low temperature, while continuous desiliconization,dephosphorization, slag-remaining and de-carbonization in the same converter.The less slag smelting technique of “slag-remaining ”and “double-slag” has been a-dopted at the same converter in JISCO.As a result,the lime consumption and the dolomite consumption in converter steel -making have been remarkably decreased.The slag generated in converter steelmaking has been decreased by 25%~33%.
