It is the specification of the furnace body, that is, the tonnage. The intermediate frequency furnace generally has 0.25T, 0.35T, 0.5T, 0.75T, 1T, 2T, 3T, 5T, 10T, etc.

Aluminum shell 250KG medium frequency induction furnace is medium frequency coreless induction melting furnace (non-vacuum). It can be controlled by silicon static medium frequency power supply for induction and heating of copper, aluminum, stainless steel and other non-ferrous metals. Generally, it is divided into furnace capacity. There are two kinds of aluminum shell structure and steel shell type structure. The aluminum shell type structure generally adopts a tilting machine-powered tilting furnace method (there are also a few hydraulic tilting furnaces), and the steel shell type structure generally adopts a hydraulically powered tilting furnace method.

The main technical parameters

How large transformer does the 250KG IF induction furnace need?

The power of the intermediate frequency power supply used in the 250KG medium frequency induction furnace determines the power. The ordinary melting power is 160 kW, and the smelting is 250 kW. If you want to faster, you can increase the power to 360kW. The general foundry requires fast smelting, which is 250kW (1kW per kilogram of molten iron) so you can consider a transformer of 160-250KVA.
