二次大战以后,在工业发达的国家中,电炉工业发展的比较迅速。从1957—1960三年间,日本电炉工业增加了2.45倍;1966—1969三年内,工业炉总数增加了1.7倍,电炉平均增加了两倍,其中感应电炉增加了2.7倍。现在,日本共有电炉制造厂三十余家。西德,从1954—1960六年间,电炉工业增长了1.6倍。据不完全统计,西德现有大型电炉专业厂共十五家左右。这些厂家在发展某一炉种上都有自己独到之处,如海拉斯公司是制造真空电弧炉的专门厂家,西欧真空电弧炉总数的70％左右都是该公司提供的;又如BBC公司,在发展电阻接触加热方面,有较丰富的经验。
After the Second World War, in the industrialized countries, the development of electric furnace industry is relatively rapid. From 1957-1960 three years, Japan’s electric furnace industry increased 2.45 times; 1966-1969 three years, the total number of industrial furnaces increased 1.7 times, an average of three times the electric furnace, of which induction furnace increased 2.7 times. Now, Japan has a total of more than 30 electric furnace factory. West Germany, from 1954-1960 six years, the electric furnace industry increased by 1.6 times. According to incomplete statistics, West Germany has a total of about 15 specialized large-scale electric furnaces. These manufacturers have their own uniqueness in the development of a furnace, such as the sealass company is a specialized manufacturer of vacuum arc furnace, about 70% of the total number of Western European vacuum arc furnace are provided by the company; Another example is the BBC company , In the development of resistance contact heating, have more experience.
