Heating method of industrial intermediate frequency furnace

Author : Hongteng Time: 2022-09-21

Industrial furnaces are used to smelt metals, and there are many types on the market. The intermediate frequency furnace that we Hongteng uses the most, adopts the principle of induction heating.

The metal heating of induction heating equipment is also called intermediate frequency induction forging furnace, intermediate frequency induction diathermy furnace, intermediate frequency induction pre-forging heating furnace, intermediate frequency induction heating furnace, and intermediate frequency induction furnace.

Today we will introduce to you about induction heating equipment.

The first is the application of the device. It involves the heating, heat treatment and melting of metals.

The heating application range is in the process of forging, extrusion, hot rolling and shearing of metal materials. Heating and heat treatment such as quenching and tempering, annealing, and tempering of the whole metal material.

The composition and configuration of induction heating equipment is generally composed of intermediate frequency power supply, electric heating capacitor, induction furnace body, feeding and discharging transmission device and temperature measurement equipment.

When using induction heating, pay attention to the cooling method of the induction coil of the equipment.

Common cooling methods are:

Closed circulating cold zone tower system, pool + circulating pump cooling system;

Pool + plate heat exchanger cooling method;

Closed cooling tower + pool cooling method;

The temperature measurement method is infrared thermometer + large-screen display + temperature measurement sorting mechanism; the material discharging method includes quick feeding machine or sorting material; the automatic control method is composed of PLC + Siemens control system.

Features of induction heating equipment:

Induction heating equipment has fast heating speed and less oxidative decarbonization. Because the principle of medium frequency induction heating is electromagnetic induction, its heat is generated in the workpiece itself. Due to the fast heating rate of this heating method, there is very little oxidation, high heating efficiency and good process repeatability.

The induction heating equipment has a high degree of automation and can realize automatic unmanned operation. The automatic feeding and automatic discharging sorting device is selected, and the special control software of Hongteng can be used to realize automatic unmanned operation.

Induction heating equipment has uniform heating and high temperature control accuracy. By selecting a reasonable operating frequency, the appropriate diathermy depth can be adjusted to achieve uniform heating and small temperature difference between the core and the surface. The application of temperature control system can realize precise control of temperature

The induction furnace body of the induction heating equipment is easy to replace and occupies a small area. According to the size of the workpiece to be processed, the induction furnace body of different specifications is configured. Each furnace body is designed with water and electric quick-change joints, which makes the furnace body replacement simple, fast and convenient.

Induction heating equipment has low energy consumption and no pollution Compared with other heating methods, induction heating has high heating efficiency, low energy consumption and no pollution; all indicators meet the requirements of national standards.

Under the condition of diathermy, the power consumption per ton of heating from room temperature to 1250 ℃ is less than 390 degrees.

This is what we share about induction heating equipment today, I hope it can be helpful to you. Welcome to Luoyang Hongteng to learn more about the intermediate frequency furnace.
