前言 用上大下小镇静钢锭模上部加铸铁顶盖浇铸沸腾钢的方法(即“ZF法”),首次在鞍钢浇铸成功。它具有双层底盘和瓶口式钢锭模的双重作用,是提高初轧成坯率、降低能耗、增加经济效益的有效方法。据此,为寻求一种既能适应攀钢现有设备及工艺条件,又能提高沸腾钢成坯率 Preface The method of casting boiling steel on the upper part of the upper and lower small static cast ingot mold cast iron roof (ie “ZF method”), the first successful casting in Ansteel. It has the dual role of double-deck chassis and bottleneck steel ingot mold, is an effective way to improve the blank-forming rate, reduce energy consumption and increase economic efficiency of the initial rolling. Accordingly, in order to find a way to meet the existing equipment and process conditions in Panzhihua Iron and Steel, but also improve the billet rate of boiling steel
