【摘要】 采用双变供氧制度和新的渣料加入量计算法，在浦钢公司30t氧气顶吹转炉上进行了新的冶炼工艺试验研究。试验表明：新的渣料加入量计算法在新工艺冶炼中符合实际，采用双变供氧制度，使起渣时间提早，有利于全程化渣，终渣（∑FeO）降低，冶炼时间缩短，石灰加入量降低，取得了一定的经济效益．更多还原

【Abstract】 In 30t oxygen top-blown converter of Pudong Iron and Steel Company, Ltd. the new technology experiment has been carried out with double changeable oxygen-supplying system and new calculation methods of slag materials. It shows that new calculation methods of slag materials conform to reality in new technology and the use of double changeable oxygen-supplying systyTn makes the prelimi-nary slag formation earlier, benefitful to slag-making in full period It also decreases (∑FeO) final slag and time period and shortens the smelting time,obtaining a certain economical effect.更多还原
