Medium frequency induction billet heater, green energy saving, efficient production

Medium frequency induction billet heater, green energy saving, efficient production

Induction billet heater is an important thermal processing equipment in metallurgical industry. One of the purposes of heating is to improve the plasticity of steel. The plasticity of steel is very low in cold state. In order to improve the hot working condition of steel, the plasticity of steel must be improved.

Generally speaking, the higher the hot working temperature is, the better the plasticity of steel is. The lower the heating temperature is, the greater the energy consumption is, the faster the wear rate of the mill is, and the lower the temperature is, the more likely the roll crack will occur. Another purpose of heating is to make the billet heated evenly from the surface to the core, from head to tail. Because of the temperature difference inside and outside the billet, there is internal stress in the metal. Billet will appear quality defects and scrap after rolling. Through uniformly heating for the billet, the temperature difference becomes smaller and smaller, and the temperature stress is avoided. The quality of billet heating directly affects the quality, production, energy consumption and rolling life of steel.

The correct heating process can improve the plasticity of steel, reduce the deformation resistance in the process of heat processing, provide good heating quality for the steel billet in time, and ensure the smooth progress of the steel rolling production. On the contrary, improper heating process, such as low heating temperature can cause overheating, overburning and rolling.

It is very important to heat homogeneous heating in the process of billet heating. The electric medium frequency billet induction heating furnace is mainly used in the heating rolling of steel billet, such as square steel round billet. The temperature control method of continuous casting billet is closed loop temperature control system, which can automatically adjust the heating temperature. A worker can operate the whole system without worrying about tahe out of control of the temperature.

The structure of induction billet heater:

1.Furnace frame (including capacitors, water lines)

2.Induction heating system

3. The storage platform and the automatic pinch roller feeding device.

4.Fast unloading device

5.Infrared temperature measurement system

6. Transformer (selected according to actual needs)

7.Capacitor (selected according to the actual needs of the user)

8.PLC operation console

9. Cooling tower

10. Power supply

Mechanical part of billet induction heating furnace

The mechanical part is composed of furnace body, feeding machine, feeding mechanism, discharging mechanism, etc. The action setting and heating speed are determined by PLC control.

1. Feed mechanism
The feeding mechanism includes a storage table, a front V groove and a conveying device. The outlet is equipped with a roller unloading mechanism, so that the material does not touch the furnace outlet.

2. Furnace body
It is a steel welded component, including waterways, circuits, gas components, capacitors, pots and copper.

3. Infrared thermometer
The temperature measuring device is a non-contact monochromatic infrared thermometer with temperature display and multiple output interfaces to connect the printer or recording equipment.
