熔炼和浇注设备近二十年来,尽管感应电炉在铸铁熔炼方面有了较大的发展。但是,甚至在主要的工业国中,铸铁熔炼主要还是采用冲天炉。如美国从1960年到1976年冲天炉拥有量减少了1/2,仅1405台,但是铸铁熔炼约80％仍采用冲天炉,主要是减少了10吨/时以下的冲天炉,增设了30吨/时以上的冲天炉,如西德据统计,铸铁熔炼约有80％是采用冲天炉,其中包括冲天炉 Melting and pouring equipment for nearly two decades, despite the induction furnace in the cast iron smelting has made great progress. However, even in the major industrialized countries, cast iron melting mainly uses cupola furnaces. For example, in the United States, the number of cupola owned by the United States was reduced by 1/2 to only 1405 units from 1960 to 1976, but about 80% of cast iron smelting still uses cupola, mainly reducing cupola at 10t / h and adding 30t / Above the cupola, such as West Germany According to statistics, about 80% of cast iron smelting is the use of cupola, including Cupola
