Application: VD-type vacuum refining furnace can conduct vacuum degassing for molten steel, alloy composition trimming and argon stirring in vacuum. VOD-type vacuum refining furnace carries out oxygen blowing and decarburization, vacuum degassing and alloy composition trimming in vacuum, mainly used for refining ultra-low carbon stainless steel, electric pure iron, etc. Features of the equipment: VD / VOD type vacuum refining furnace can adopt either single or dual station. Overhead, pit or vehicle-mounted arrangement can be selected for vacuum tank. Unscrewing and vehicle-mounted movement are optional ways for movement of the vacuum tank It consists of: Vacuum tank, vacuum tank cover and lifting mechanism of the cover, steel ladle, oxygen lance mechanism, vacuum charging device, temperature measurement and sampling and observation system, oxygen system, argon system, cooling water system, vacuum pump system, etc. Technical parameters Rated capacity (T) Ladle shell inner diameter (mm) Vacuum pump suction capacity kg/h Working vacuum degree (Pa) Size of vacuum tank (mm) 15 2200 150 67 3800×4100 25 2600 180 4000×4600 30 2700 200 4200×5175 40 2900 250 4800×5300 50 3000 280 5300×5400 60 3150 360 5300×5500 70 3200 380 5400×5600 80 3300 380 5500×5700 90 3400 380 5600×5800 100 3500 400 5600×5800 120 3600 420 6200×6400
