We all know that the induction coil is an important part of the medium frequency induction heating machine and is necessary for heating the workpiece. Therefore, the quality of the induction coil directly affects the quality of the workpiece. However, during long-term use, the induction coil sometimes suffers from poor insulation effect. Today, the editor will tell you the reasons for this phenomenon.
(1) Poor cooling and excessive temperature will cause the insulation layer to deteriorate and cause ignition and carbonization.
(2) The reactor coil is loose, and the relative motion friction between the coil insulation layer and the coil insulation layer, and between the coil insulation layer and the iron core causes damage to the insulation layer.
(3) When dealing with reactor coil scale, acid penetrates into the coil. The acid corrodes the copper tube and generates copper salts that destroy the insulation layer.
(4) When the furnace lining is removed, the method of pumping water for cooling is adopted. When the new furnace lining is sintered, water is separated out, causing the current at the contact part between the coil and the yoke to increase and the insulation layer to be damaged.
This article briefly analyzes the reasons for the poor insulation effect of the induction coil of the medium frequency induction heating machine, and you can find a reasonable solution based on the reasons. Of course, you can also consult our technical staff if you encounter any problems during actual operation.
