近年来,苏联遵循节约材料和劳动费用的方针,特别注意加速发展冶金和机器制造的必要性。在铸造生产中,就是要在感应熔化炉内熔化合成和高强度牌号的铸铁来最完善和综合地解决这些课题。 广泛应用感应熔化炉来替代冲天炉有以下几个主要理由:它可获得优质高强度的铸铁;能够利用较便宜的次等炉料;能够大大节约短缺的焦炭;能够腾出一部分大型炼铁高炉。 根据高尔基汽车厂和莫斯科水表厂的工厂成本资料看,改为用感应炉熔化1吨铸铁可降低工厂成本18～25卢布。
In recent years, the Soviet Union has followed the principle of saving materials and labor costs, paying particular attention to the need to speed up the development of metallurgy and machinery. In casting production, it is the most perfect and comprehensive solution to these issues by melting synthetic and high-strength cast iron in an induction melting furnace. There are several major reasons why induction furnaces are widely used instead of cupola furnaces: they obtain high quality and high strength cast iron; they can make use of less expensive secondary charges; they can greatly reduce the shortage of coke; and can make part of a large ironmaking blast furnace. According to the Gorky automobile plant and the Moscow meter factory cost information to see, instead of using an induction furnace melting 1 ton of cast iron can reduce the factory cost of 18 to 25 rubles.
