The difference between aluminum shell induction melting furnace and steel shell induction melting furnace

At present, in the intermediate frequency industry, the intermediate frequency melting furnace is divided into steel shell with yoke hydraulic tilting furnace and aluminum shell with reducer tilting furnace. usually

steel shell induction melting furnace:

has a long service life (generally the normal service life is more than 10 years),

Good stability, because it uses a magnet, the magnet has two functions: first, the magnet is firmly fixed with the top wire and the induction coil, so that the coil and the magnet form a stable structure. Second, the permeable magnet can form a permeable barrier around the coil;

Energy saving, because the furnace with a magnetic conductor saves electricity by 3%-5% compared with the aluminum shell induction melting furnace body;

The casting point is stable, and the hydraulic tilting furnace device can well control the casting angle and speed;

The safety performance is good. Because of the characteristics of the leaking alarm device and the refractory cement layer), the steel shell structure is selected for its good characteristics when the tonnage is greater than 2T.

Aluminum shell induction melting furnace:

aluminum shell induction melting furnace is a simple structure, the service life is generally about 5-8 years, there is no magnetizer, lining ejection mechanism, refractory cement layer, its safety performance is poor, and generally used with a capacity below 2T. For example: a set of 5T intermediate frequency furnace, when the furnace is full of molten iron, the overall weight of the equipment reaches 8-10T. If the aluminum shell structure is selected, when the reducer rotates the furnace body to 95 degrees, the entire furnace body will tilt forward, which is very safe. Difference. Aluminum shell induction melting furnace is suitable for users who change production in a short time, with small tonnage.
