Description

Intermediate frequency valve heating furnace Technical Field The utility model relates to the technical field of heating furnaces, in particular to an intermediate frequency valve heating furnace. Background When valve parts, particularly valve stems, valve flaps, valve seats, require high hardness, high wear resistant surfaces, quench-hardening is one of the preferred processes, and medium frequency induction heating is one of the most common and efficient methods for achieving this process. The intermediate frequency furnace is induction heating equipment for converting power frequency 50HZ alternating current into intermediate frequency (more than 100HZ to 8000 HZ) alternating current, and utilizes the intermediate frequency electromagnetic induction heating principle to heat a metal workpiece, and when the metal workpiece is heated, the metal workpiece and the intermediate frequency electromagnetic induction heating equipment enable the workpiece to self-heat so as to achieve the heating purpose, and the metal workpiece is not contacted.
