前言在整个机械工业中,热处理是耗电量最大的行业之一。它的全部工作几乎是要靠各种工业电炉来完成。盐浴炉是热处理的一个重要加热设备,它加热工件均匀,加热速度快,氧化脱碳趋向小,能够进行局部加热和液体渗碳。但是盐浴炉的热效率低,能耗大,难以适应生产的发展, Preface Throughout the machinery industry, heat treatment is one of the industries that consume the most electricity. It’s almost all the work to rely on a variety of industrial electric furnace to complete. Salt bath furnace is an important heat treatment equipment, heating it evenly, heating speed, oxidation decarburization tends to be small, to local heating and liquid carburizing. However, the thermal efficiency of salt bath furnace, energy consumption, difficult to adapt to the development of production,
