Medium Frequency Smelting Furnace

Induction Coil should be fired of Anaerobic Rectangle thick-walled Red Copper, thickness of Tube Wall should be uniform, and Hydroelectric Connectors should be durable and easily disassemble. There are water-cooled coils at the upper part and lower part of Induction coil to make the lining material being heated uniform and even axially as well as to extend service age for the furnace liner. To strengthen the insulation effect of induction coil, the surface of induction coil should be painted with high-strength insulation resin, and at inside, outside and interims of the induction coil should be applied with Refractory Daub(refractoriness (1800 C).

The Refractory Daub is with excellent insulation and heat shielding performance, which will protect the induction coil from being damage if the furnace liner is broken. With plenty of experience accumulated from designing adjusting, certain quantity of experimental data about Height-Diameter Ratio (H/D Ratio) is built up. We applied different H/D Ratio for inductors with different capacity; this Computer Optimal Designed H/D Ratio greatly improved the efficiency of inductor.
