The mechanical vacuum degassing furnace system consists of 16 first-stage oil rotary pumps, 8 second-stage Roots pumps, and 20 third-stage Roots pumps.
READ MOREVacuum heat treatment is a metal heat treatment process in which the metal workpiece is heated below 1 atmosphere pressure (that is, under negative pressure). Among them, the vacuum environment in which the vacuum heat treatment is located includes low vacuum, medium vacuum, high vacuum and ultra-high vacuum.
READ MOREFirst, the molten steel is sucked into the vacuum chamber, and then argon is blown into the molten steel on the side walls of the two risers. The argon gas rapidly expands under the action of the high temperature of molten steel and the low pressure of the upper part of the vacuum chamber, causing t
READ MOREThe influence of direct reduced iron (DRI) on electric arc furnace steelmaking1. Productivity and yield Production practice shows that adding DRI has a great impact on the productivity and yield of the electric arc furnace. In recent years, the number of large electric arc furnace plants newly built
