Silicon controlled medium frequency induction heating furnace

The thyristor intermediate frequency induction heating furnace means that the power supply of the intermediate frequency induction heating furnace adopts thyristor as the main frequency conversion component.

Commonly used are thyristor full bridge parallel inverter variable frequency power supply or thyristor half bridge series inverter variable frequency power supply.

An induction heating furnace using thyristor as an intermediate frequency power supply is often called a thyristor intermediate frequency induction heating furnace.

The principle of thyristor intermediate frequency induction heating furnace:

The intermediate frequency power supply of the thyristor intermediate frequency induction heating furnace is a thyristor frequency conversion device, which can convert the three-phase 50Hz alternating current to the heating frequency commonly used in the intermediate frequency induction heating furnace.

In the SCR parallel inverter of the thyristor intermediate frequency induction heating furnace, the parallel compensation capacitor and the induction coil of the electric furnace form a self-oscillating circuit, which reduces the load of the electric furnace.

Application of thyristor medium frequency induction heating furnace: used for overall or partial induction heating of steel rods, steel pipes, copper rods, aluminum rods, stainless steel and other metal workpieces.

SCR medium frequency induction heating furnace heating material: carbon steel, alloy steel, Q235q, Q345q, Q245R, A32, D32, A36, D36 and other metal workpieces

Heating temperature: medium carbon steel Heating temperature: 1250℃ Temperature difference requirements: radial temperature difference≤60℃, head and tail temperature difference≤80℃

Features of thyristor intermediate frequency induction heating furnace:

The heating temperature is uniform, the temperature control precision is high, the temperature difference is small, and there is no pollution.

The power rectification and inverter circuit devices of the thyristor intermediate frequency induction heating furnace mostly use module devices instead of single power devices. In order to achieve greater power, series, parallel or series-parallel connection of power devices is used

The startup success rate is high and the reliability is strong. Variable frequency / variable load adaptive, the most specifications and varieties of steel induction heating capacity. Users can choose manual furnace change or automatic furnace change to obtain a wide range of applications, so that the utilization rate of the induction heating furnace can be maximized.

A large number of digital integrated circuits and special integrated circuits are used in the control circuit and protection circuit of the thyristor intermediate frequency induction heating furnace, which simplifies the design of the circuit and improves the reliability of the equipment.
