Screw vacuum pump in metal smelting

As we all know, in the metallurgical industry, high vacuum smelting is widely used for production or processing, especially in some high-end fields, the requirements of impurity content, oxygen, nitrogen and even hydrogen content of products are extremely strict, so high standards and requirements of vacuum system are required.

For example, vacuum distillation (the more advanced vacuum unit composed of dry screw vacuum pump and roots vacuum pump): in the distillation tank with vacuum degree higher than 1.3 PA, the reduction product is heated at 900-950 ° for a long time, and magnesium and magnesium chloride can volatilize and condense on the condenser.

This is mainly because of the following points:

1: It can greatly reduce the boiling point of the reduced product and make it easier to volatilize.

2: It can greatly increase the volatilization rate. The volatilization rates of different substances vary greatly under different vacuum degrees.

3: Prevent the production of Ti-Fe alloy or other compounds from affecting the product quality.
