The addition of a small amount of silver, whilst not increasing the melting point of copper, does increase the recrystallisation temperature by almost 100℃, and also helps to give better thermal conductivity at the operating temperatures.

The continuous casting of molten steel into billets, blooms and slab products, has been highly refined over the years into an extremely sophisticated system. The continuous casting process is expected to produce metallurgically sound products at the lower possible cost, and this is being achieved in many steelworks throughout the world.

The mould must exhibit excellent thermal conductivity, be resistant for thermal erosion ,and be resistant to distortion from thermal stress. So far only copper and a few copper alloys meet the above conditions, both economically and technically.

SOLIDIFICATION

Over the years, Metallurgists and Engineers have been working together to develop better continuous casting moulds. The steel companies require a more economical mould which will give a longer service life. Surface coating of the inner walls of the mould has given the best results to date. Coatings available are Chromium and Nickel plating. Also, a combination of the two give good results on slab casting.
