Taiyuan Iron and Steel Plant in early July this year, installed a set of molten steel vacuum processing equipment, this set of equipment is the use of reciprocating vacuum pumps and water column vacuum pump joint operation, the operating procedures are as follows: As shown above, in the ladle is not placed in a vacuum Previously, a reciprocating vacuum pump was used to reach a vacuum in the vacuum tank, at which time the gate 1 was closed. After the ladle is placed in the vacuum chamber and sealed, open the gate 1 again. Because the vacuum tank is vacuum, after the gate 1 is opened, the gas in the vacuum chamber is directed
