Graphite moulds are generally used for
continuous casting method because
The metals wet the mould slightly
Only a small of lubricating oil is
required
They are self-lubricating
They are comparatively cheaper
They are self-lubricating
Reasons of using graphite moulds for
continuous casting method are :
1. They are self-lubricating
2. Low wettability
3. High thermal conductivity and low
coefficient of thermal expansion
4. High thermal shock resistance
Hence, the correct option is (C).
