company news about Working principle, structure composition and function of vacuum induction melting furnace

Working principle of vacuum induction melting furnace:

Vacuum induction melting furnace is a complete set of vacuum smelting equipment which can melt metal by medium frequency induction heating principle under vacuum condition. Suitable for scientific research and production units of nickel base alloy and special steel, precision alloy, superalloy, non-ferrous metal and alloy in vacuum or protective atmosphere for melting and casting. It can also be used for smelting and casting of rare earth metals and hydrogen storage materials.

The structure of vacuum induction melting furnace:

Main structure and composition: according to the structure form can be divided into vertical and horizontal two series. According to the discharge way vertical series is divided into upper discharge, lower discharge, side discharge three forms; Horizontal series is divided into two forms: bottom discharge and upper discharge.

Its main components are: electric furnace body (including melting device), vacuum system, power intake device, water cooling system, hydraulic system, pneumatic system, electrical control system, medium frequency power supply.

The function of vacuum induction melting furnace:

In the process of melting, temperature measurement, sampling, ramming, observation, main feeding and alloy composition adjustment can be carried out without destroying the vacuum of the melting chamber. At the same time, inert gas can be filled through the filling valve to control the pressure and atmosphere in the furnace. It can be poured with one ingot and multiple ingot, loaded into preheat and insulation ingot mold, water cooled ingot mold, sand box and centrifugal casting. According to the functional form, it can be divided into periodic type and semi-continuous type operation.
