Induction heating furnace

Induction heating furnace

The induction heating furnace is the main heating equipment for heating metal before forging. There are many heating methods. For different forging processes, different forging blank heating methods and heating temperatures are adopted, and the structure and heating methods of the heating furnace are different. Now introduce the induction heating furnace .

 

A. Purpose of induction heating furnace heating:

Improve metal plasticity, reduce metal deformation resistance, make it easy to form, and obtain good structure and mechanical properties after forging

B. Heating requirements of induction heating furnace :

1. Under the conditions of temperature conductivity and internal stress allowed by metal materials, the induction heating furnace should be heated to the predetermined temperature at the fastest speed to improve efficiency and save energy.

2 , an induction furnace to minimize the heating of the metal absorb harmful gases, such as oxygen, hydrogen, nitrogen and other gases, and reduction of oxidation, hydrogen embrittlement or decarburization defects and improve the quality of the heating.

3 , induction heating furnace in the low-temperature heating stage, to prevent undue heating of the metal section and the outer core portion excessive temperature difference, resulting in excessive thermal stress, internal stress and then overlay the other, causes the material to rupture.

4 , an induction heating furnace can accurately implement a given specification is heated, the heating conditions such as heating temperature, speed, time and thermal insulation, to prevent overheating, over-burning and other defects.

C. Suitable forging process of induction heating furnace :

The suitable forging process of induction heating furnace is divided into hot forging and warm forging according to temperature; according to the forming method, it can be divided into different forging types such as free forging, die forging, ring rolling, and special forging.

D. Heating method of induction heating furnace :

The heating method of the induction heating furnace is an induction heating method, and an intermediate frequency induction heating furnace is generally used to heat the metal blank. The intermediate frequency induction heating furnace adopts the principle of electromagnetic induction heating. The induction current is generated through the resonance of the intermediate frequency power supply and the inductor (induction coil) . The intermediate frequency induction heating furnace has fast heating speed, uniform heating temperature, easy operation, easy maintenance, energy saving and environmental protection, and heating burn loss Few features, especially the application of automatic control, which meets the requirements of the current smart factory, can realize the automation of the forging production line , and is deeply loved by people in the forging industry.
