380V Induction Air Cooling Pipeline Post Weld Heat Treatment Machine
Introduction of intermediate frequency heat treatment:
Due to its high energy density, the intermediate frequency heat treatment equipment can easily handle the heat treatment of pipes with large diameters and thick walls. For example: headers, large pipe bases, pipes with large diameters and thick walls, and overhaul operations (due to limited installation space for overhaul operations, intermediate frequency heat treatment equipment can provide high power density in a small space, while ceramic sheets cannot be deployed due to limited space. Sufficient power) In addition, it is also widely used in the chemical industry, shipbuilding, and pre-weld preheating and post-weld heat treatment of steel structures.

Advantages of intermediate frequency heat treatment equipment:
Induction heating is to make the metal self-heating, and resistance heating is to transfer its own heat to the heated object through heat conduction, which is more than 30% more efficient than resistance heating;
The medium frequency electromagnetic wave has a certain penetrating ability and can achieve the effect of uniform heating ;
The power density of the intermediate frequency heating equipment is high and the heating speed is fast, which can significantly improve the working efficiency.
Applications of Air-Cooled Induction Heating Machine :
Recommended advice:
Because the heat treatment process takes a long time, the actual power used by the equipment is not very large. Generally, the power selection is carried out in combination with the material, diameter, thickness and heating temperature of the pipeline. Usually, 60kw is recommended for 500mm diameter, and 100kw is recommended for 500-1200mm diameter.
Frequency selection: verified by field operation, the heating effect is the best when the frequency is 2K-5KHz
