Graphite dies for continues casting of aluminium, copper
The process of continuous casting essentially is that of pouring molten metal into a graphite die, which is water-cooled. The metal then solidifies and is withdrawn from the die by means of take off rollers.
This process offers the advantage of non-stop production and also ensures optimum material quality.
When continuous casting with the die adjoining the melting chamber, two alternative procedures are possible:
- Casting with horizontal installation
- Casting with vertical installation
Advantaged of graphite are:
- Low surface wetting by molten metals
- High thermal and chemical resistance
- Increasing strength with a rise in temperature
- Good lubricating and frictional proper
- Excellent resistance to temperature change
- High thermal conductivity
Complicated parts with close tolerances can be machined into required shape.
