Features of Low Frequency Induction Furnace
ugged and Long Life Furnace Body with Shell
Furnace body composed of thick steel shell plate is high rigidity and is suitable for the use of long term and frequent tilting operation.
Steel shell protects the heating coil from cutting wastes or scattering molten metals.
Easy Coil Replacement with Compact Coil Unit Design.
Users can easily replace the coil unit which is assembled by own strong clamping.
High Reliable Coil Insulation
Heating coil employs the insulation of high quality molded with silicon rubber and mica insulation of Class H and therefore it prevents from the short circuit accident causing of dew condensation and cutting wastes etc.
The outer surface of coil employs two layers of special insulation.
Safe and Reliable Hydraulic Tilting Device
Tilting device employs a hydraulic system of a smooth operation and hydraulic fluid of fireproof class.
High Reliable Metal Leak Detection Device
It uses a unique method to be plastered special electrodes between coil cements as well as high frequency furnace.

- Melting time and power consumption are attained when the furnace is operated with hot lining sufficiently and smelts cooled materials up to 1500℃ and molten metal is tapped about 1/3 amount of furnace capacity every time.
- Heating rate and power consumption at heating mean that molten metal is heated to 100 degrees during from 1300 degrees to 1500 degrees. In any case, the times or electric power required for charging/discharging, slag-off, ingredient adjustment, temperature measurement, etc. are not included.
