Vacuum Refining Equipment
Energy saving and consumption reduction — benefiting mankind and the social environment
Process Types
- VD — Vacuum degassing, suitable for single furnace capacities of 5–300 t
- VOD — Vacuum decarburization and degassing, suitable for single furnace capacities of 10–120 t
- RH — Vacuum rapid circulation degassing, suitable for single furnace capacities of 70–300 t
- AOD — Argon-oxygen combined refining, suitable for single furnace capacities of 6–180 t
- LFV — Non-vacuum heating plus vacuum degassing, suitable for single furnace capacities of 10–60 t
Refinable Steel Grades & Vacuum Pumps
The steel grades that can be refined include ball bearing steel, alloy structural steel, tool steel, stainless steel, roll steel, spring steel, high-quality carbon steel, and many other grades. The vacuum pumps are available as steam jet vacuum pumps or fully mechanical vacuum pumps; users can choose appropriately according to their energy resources.
