Product Description

KGPS Series Medium Frequency Power Supply


Introductions:
Medium frequency induction heating technology is to heat the workpiece through the principle of electromagnetic induction and the use of eddy currents. Induction heating has a series of advantages such as fast heating speed, high internal heating efficiency of materials, uniform and selective heating, good product quality, almost no environmental pollution, good controllability and easy to realize production automation, so it has developed rapidly in recent years.

At present, induction heating has been widely used in casting smelting, forging blank heating, metal surface heat treatment, aluminum electrolysis and other industries. Most of the traditional heating methods in these industries are based on coal, oil, gas or box-type electric furnace heating, which has defects such as high energy consumption, poor working conditions, serious environmental pollution, and difficult to control process quality. Therefore, the comprehensive promotion of induction heating technology is an inevitable trend for the transformation of traditional industries.
