2 .3 Vacuum induction melting furnace
| Total power of 300kg vacuum furnace: 420kW | IGBT power supply: 350kW |
| Control power supply: 70kW | Crucible maximum capacity: 350kg (molten copper) |
| Melting time: ≤ 90min | Normal operating temperature: 1600ºC |
| Crucible inclination angle: The furnace body tilts forward about 110° | Protective atmosphere: N2 /Ar |
| Cooling water inlet pressure: 0.2MPa | Water consumption of a single unit: 60m³/h |
| Ultimate vacuum degree of melting chamber : 5 × 10- 3 Pa (Empty furnace cold state without coil) | |
| Smelting chamber pressure rise rate (empty furnace, cold state, no coil): ≤ 5Pa/h | |
| Working vacuum degree of the smelting chamber (the molten steel is clear and the liquid surface is not volatile): 6.6 × 10- 2 Pa | |
| Furnace tilting method: Automatic hydraulic control is used to drive the coil in the furnace to flip over and cast at a fixed point. | |
| Control method: touch screen and cabinet button operation | Overall dimensions (length, width, height): 9m×8m×5m |
Equipment is designed to comply with the following standards:
