Induction heating speed is fast, and the efficiency is high, the rapid preheating can be realized, and the preheating temperature can be accurately controlled by adjusting the parameters and input power of the induction coil.

[0023] A sealing door 101 is mounted on one side of the outer portion of the preheating furnace body 1, and an exhaust pipe 102 is mounted on one side of the top end of the preheating furnace body 1. A through slot 301 is arranged at the middle position of the inner portion of the support table 3. The exhaust pipe 102 can be connected with an external waste gas purification machine, so that the gas generated by heating in the preheating furnace body 1 is purified and treated, and the hot air can pass through the through slot 301 arranged on the support table 3 and enter the inner portion of the inner cavity 5 through the air hole 503 at the bottom end of the inner cavity 5.
