Before casting, liquid pig iron contains a significant amount of unwanted gases, such as nitrogen and oxygen. During the degassing process, liquid pig iron is either poured into a vacuum container, where gases are removed, or vacuum guns are used to extract the contained gases.

Due to the large volume of gases, steam ejectors are used as vacuum generators. To save costs, liquid ring vacuum pumps are sometimes used in conjunction with steam ejectors.

As a professional manufacturer of liquid ring vacuum pumps and vacuum compressors, Atlas (Yantai) Vacuum Technology Co., Ltd. can assist in pump selection, system design, engineering, installation, and startup. Our 2BE and 2BV liquid ring vacuum pumps are widely used in the steel degassing industry.
