钢包精炼是目前炼钢领域里的一个重要发展方向。这个概念的实质,是在钢包中联合运用真空、吹气(惰性气体或渗入部分活性气体)、造渣(包括吹粉末)、强制搅拌(感应搅拌或吹气搅拌)和电加热(自由电弧、等离子弧、电渣加热、感应加热)等手段来完成精炼钢水、调整温度、成分等任务。自从ASEA-SKF和六十年代创制成功以来,生产实践业已证实这是一种能稳定地生产清洁钢的可靠方法。但ASEA-SKF法投资太大,生产周期也较长,因而近年来又
Ladle refining is currently an important development in the field of steelmaking. The essence of this concept is the combination of vacuum, blowing (inert gas or partial reactive gas), slagging (including blowing powder), forced mixing (inductive stirring or air blowing) and electrical heating (free arc, Plasma arc, electroslag heating, induction heating) and other means to complete the refining of molten steel, adjust the temperature, composition and other tasks. Since the successful creation of ASEA-SKF and the 1960s, production practices have proven to be a reliable way of producing clean steel consistently. However, ASEA-SKF investment is too large, the production cycle is also longer, and thus in recent years
