Using sealed flange in the top of the furnace, and the whole furnace shell is completely closed to achieve vacuum degassing;

The lid of water-cooled is directly connected with the multi-stage mechanical vacuum pump system, which can directly degassing in the metal molten pool;

The induction coil is equipped with a Power supply with the power and frequency matched for fast melt rates (high productivity) and optimum stirring (metallurgical quality) in the liquid state;

A proper stirring frequency not only ensures the alloy stirring uniformity, but also ensures that the tumbling liquid metal can be fully degassing;

The harmful gas components are removed by vacuum and carbon-oxygen reaction, and the content of hydrogen, nitrogen and oxygen is lower than that of the metal melted in the atmosphere;

Molten steel can be poured into launcher or ingot molds under atmosphere. The casting process is usually completed under atmosphere (it can also be cast under protective atmosphere).
