This paper gives a comprehensive account of the achievements made by the former Soviet Union in the development and use of circulating vacuum processing equipment. The author gives the parameters of a ladle vacuum processing equipment with a capacity of 100-400t and shows the interrelationship among the parameters through experiments. The purpose of determining reasonable parameters is to save gas usage and to reduce the temperature drop of the metal during vacuuming. OK resistance
