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
