文摘：
Vacuum degassing (VD) and vacuum oxygen decarburization (VOD) are the main processes in secondary steel-making. The large volumes of dissolved contaminant gases arising and the generation of metallic fines and oxide dust require robust high-capacity pumping equipment. Today's advanced dry mechanical vacuum pumping systems are superior to previously used systems in that they enable better dust handling, increased pumping speed, and reduced operational and maintenance costs.
