What is induction melting?
Induction melting is a cost-effective and energy-efficient method of raising the temperature of a metal to its melting point and to hold that temperature to perform metallurgical processes such as smelting, alloying, mixing, and casting.
Two types of furnaces are used in induction melting:
KGPS intermediate frequency induction furnace--Using KGPS intermediate frequency power supply, the frequency is small, but the power can be relatively large, the maximum can be 4000KW. Suitable for large-scale foundries, such as large-capacity industrial iron melting furnaces, stainless steel melting furnaces, steelmaking furnaces, billet induction heating furnaces, etc.
IGBT intermediate frequency induction furnace--Using IGBT intermediate frequency power supply, the advantage of this power supply is high electrical efficiency, which can generally reach more than 90%. Therefore, it saves 10-20% of electricity than the thyristor, and has little impact on the power grid. Generally suitable for small-capacity aluminum melting furnace, copper melting furnace, zinc melting furnace, induction heating of steel wire, etc.
Induction billet furnaces can heat billets to temperatures ranging from room temperature to over 1200°C.
After the Slab is pulled out from the continuous casting machine,Surface temperature is 750 ~ 850℃.
Induction online heating of large steel pipes is widely used in the heat treatment of various high alloy steel pipes required in oil drilling, geological drilling, coal mining, infrastructure exploration and other fields.
