screw vacuum pump in metal smelting

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

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

In China, slide valve vacuum pump and oil diffusion pump are widely used, and the process of high vacuum distillation is generally more than 100 hours. And foreign countries, especially the United States, Ukraine, the European Union and so on, have adopted the vacuum unit form of good Kaide screw vacuum pump garoz vacuum pump. It not only greatly reduces the distillation time, but also greatly improves the product quality. In addition, it not only has a great relationship with the product quality, but also greatly reduces the energy consumption: reducing the distillation time, directly reducing the electricity cost. Since there is no water pollution, the cooling water can be recycled.
