Advantages and disadvantages of steel shell induction melting furnace and aluminum shell induction melting furnace

　　Compared with aluminum shell induction melting furnace, steel shell induction melting furnace has five advantages:

　　1) Strong and durable, beautiful and generous, especially the large-capacity furnace body, which requires a strong rigid structure. From the safety point of view of tilting the furnace, try to use a steel shell induction melting furnace.

　　2) The yoke made of silicon steel sheet shields and emits the magnetic field lines generated by the induction coil, reduces magnetic flux leakage, improves thermal efficiency, increases output, and saves about 5%-8%.

　　3) The existence of the furnace cover reduces the heat loss and improves the safety of the equipment.

　　4) Long service life, aluminum is oxidized more severely at high temperature, resulting in fatigue of metal toughness. At the site of foundry enterprises, it is often seen that the shell of aluminum shell induction melting furnace that has been used for about a year is in a rotten state, while the steel shell induction melting furnace has less magnetic flux leakage, and the service life of the equipment is much longer than that of aluminum shell induction melting furnace.

　　5) The safety performance of the steel shell induction melting furnace is much better than the aluminum shell induction melting furnace. The aluminum shell induction melting furnace is easy to deform due to high temperature and heavy pressure during melting, and the safety is poor. The steel shell induction melting furnace uses a hydraulic tilting furnace, which is safe and reliable.

According to industry habits, the aluminum alloy structure supply melting furnace with a reducer as the tilting furnace is commonly known as aluminum induction melting furnace. Steel structure induction melting furnaces with hydraulic cylinders as tilting furnaces are commonly known as steel shell induction melting furnaces.
