一、设置熔化炉的动向 冲天炉和感应电炉占据了灰铸铁熔化炉的大部分,但还没有准确的统计数字。据日本铸物工业会1983年的调查报告,大概的数字是,该会所属会员工厂共有熔化炉1504台,其中冲天炉924台,工频炉和高频炉435台。除此之外作为熔化炉,还有电弧炉、重油炉等。因台数很少,本文不计在内。 1.感应电炉的动向 工频感应电炉在日本正式作为化铁炉,是在五
First, set the trend of melting furnace Cupola and induction furnace occupy most of the gray iron melting furnace, but there is no accurate statistics. According to a survey report made by Japan Foundry Industry in 1983, the figure for the membership is 1504 melting furnaces, of which 924 are cupola, frequency furnace and high frequency furnace. In addition, as a melting furnace, as well as electric arc furnace, heavy oil furnace. Due to the small number of Taiwan, this article does not include. 1. The trend of induction furnace Frequency induction furnace in Japan as a formalized iron furnace, is in five
