有芯感应电炉具有加热快、生产率高、效率高、金属烧损少、质量好、操作方便、劳动条件好、造价较低等优点。一般用于有色金属和黑色金属的熔化或保温,特别适用于金属品种比较单一的连续生产的作业。 建国初期我国就开始在工业中应用有芯感应电炉,一般用作熔化铜及铜基合金。随着国民经济的发展,越来越多的金属熔化或保温需要此种电炉,但由于此种电炉熔沟的耐火材料 Cored induction furnace with fast heating, high productivity, high efficiency, less metal burning, good quality, easy operation, good working conditions, low cost and so on. Generally used for non-ferrous metals and ferrous metals melting or insulation, especially for a single continuous production of metal varieties of operations. Early in the founding of our country began to apply in the industry core induction furnace, generally used for melting copper and copper-based alloys. With the development of the national economy, more and more metal melting or insulation needs such an electric furnace, but due to the melting furnace refractory
