Abstract
The main methods of steel vacuuming are considered in the work and vacuum units VD and RH are compared. The calculation performance of vacuum systems for 180-ton ladle is done. An overview of the cyclical operation of various types of vacuum tanks, which shows that the average daily capacity of the RH installation above the VD installation is 5-10% reduced. A method for increasing the annual productivity of a vacuum cleaner by installing a two-position evacuation system is considered: two working vacuum chamber RH and two vacuum chamber and a common vacuum cover for the VD process.
