Refractory coating to the metallic mould helps in reducing the chilling effect on the casting. Correct Answer True

Metallic mould is made of metal capable of withstand high temperature and coated with refractory wash to reduce its chilling effect on the cast and also facilitates the removal of cast product from the mould cavity. It also helps in better surface finishing of the casting material.
