感应加热的最大特点是把工件直接加热,其最大优势是工件加热速度快且热场均匀,温度易于控制,加热过程中不会混入金属杂质,工件加热金属烧损小,工人劳动条件好等,因而在工业生产中应用比较广泛。当前,在机械制造装备工业,尤其是冶金工业方面感应加热主要用于铸造熔炼、透热、淬火、烧结和钎焊等方面。 Induction heating is the most prominent feature of direct heating of the workpiece, the biggest advantage is that the workpiece heating speed and uniform thermal field, easy to control the temperature, the heating process will not be mixed with metal impurities, the workpiece is heated metal burning small, good working conditions of workers, Therefore, it is widely used in industrial production. At present, induction heating in the machinery manufacturing equipment industry, especially in the metallurgical industry, is mainly used for casting, diathermy, quenching, sintering and brazing.
