Embodiment Construction

[0031] Referring to the accompanying drawings, the present invention retains the carburizing device 13, the muffle tank 4, the airflow stirring fan 8, the motor 9 and the carburizing furnace shell 5 of the prior art. The outside of the muffle tank 4 is provided with an insulation layer 3 , and the outside of the insulation layer 3 is provided with an inductor 2 . The outside of the muffle tank 4 is provided with a temperature detection head 6 in contact with it, and the detection head 6 is connected to the control system 12 through an external wire 11 . The sensor 2 is preferably a hollow sensor, and a water circulation pipe 10 connected to an external water circulation system can be arranged in the hollow of the sensor 2, so that the temperature of the sensor 2 itself will not be too high. Specifically, the detection head 6 can be a thermocouple.

[0032] The invention adopts the principle of induction heating, and replaces the traditional heating electric furnace wire and t...

Abstract

A medium frequency induction carburizing furnace comprises a carburizing device, a muffle tank, an air current stirring fan, a motor, and a carburizing furnace casing. An insulation layer is arranged on the outside of the muffle tank, and an inductor is arranged on the outside of the insulation layer, wherein the inductor is mounted on the fixed frame and communicates with the power supply by the external copper. A temperature detector head is arranged on the outside of the muffle tank and communicates with the control system by external conducting wire.

Description

technical field [0001] The invention relates to a medium frequency induction carburizing furnace. Background technique [0002] The intermediate frequency induction adopts the semiconductor device thyristor, which has the advantages of large capacity, high efficiency, good control characteristics, long life, and no pollution. The basic application of power semiconductor devices is the control of rectification, chopping, frequency conversion, switching, etc. of electric energy, and it is a bridge between weak current control and controlled strong current. Inversion and frequency conversion are the process of converting DC into AC by using the characteristics of thyristors. If the DC is converted into 50Hz AC and the DC power is fed back to the AC grid, this inverter becomes an active inverter. The alternating current into the alternating current with adjustable frequency is called frequency conversion. Frequency conversion current has been widely used in AC motor speed regu...
