Abstract

An intermediate frequency induction carburizing furnace retains the carburizing device, muffle tank, airflow stirring fan, motor and carburizing furnace shell in the prior art. An insulation layer is arranged on the outside of the muffle tank, and an inductor is arranged on the outside of the insulation layer. The inductor is arranged on a fixed frame and connected to a power supply through an external copper bar. The outside of the muffle tank is provided with a temperature detection head in contact with it, and the detection head is connected with the control system through an external wire. The invention solves the technical problems of low working efficiency, high production cost and short service life in the background technology. It can greatly reduce the thermal pollution of the working environment of the electric furnace, has good carburizing effect, is convenient for automatic control, saves energy and time.

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...
