HGM—0.5吨三相电弧炉,在我国年产1000～150吨铸钢件的铸钢车间中,还相当普遍地应用着。该炉是五十年代设计的产品,人工加料、结构陈旧、劳动强度大、热利用率低。为此,国内曾有不少使用单位对其作过改造,虽然有收效,但仍有不少问题没解决。1979年我厂对该炉从加料方式、电极夹持及炉体的倾动三个方面进行技术改造,收到满意效果。
HGM-0.5 tons of three-phase electric arc furnace, cast steel plant in China with an annual output of 1000 to 150 tons of castings, but also quite widely used. The furnace is designed in the fifties products, artificial feeding, outdated structure, labor-intensive, low heat utilization. For this reason, there have been quite a number of domestic units that have done some remodeling of them. Although effective, many problems remain unsolved. In 1979, the factory carried out the technological transformation to the furnace from three aspects of feeding method, electrode holding and tilting of the furnace, and received satisfactory results.
