●The aluminum shell furnace body is made of thick high-quality aluminum alloy shell to reduce the magnetic leakage while ensuring the strength of the furnace;  

●The thick-walled induction coil used by Hengtai uses T2 standard copper tube to provide more smelting energy, and the open space of the induction coil improves the electric efficiency;  

●The open bottom of the furnace reduces the water vapor, and the cooling ring is designed at the bottom to extend the life of the lining;  

●The whole use of integral refractory bricks instead of ordinary asbestos rings greatly reduces the cost of using the furnace body.
