Round Copper
Mould Tube
The rapid development of the iron & steel industry has led to a transformation in the steel manufacturing process. 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 function of copper mould tube round shape is to receive the molten steel and to allow rapid heat transfer and enable quick solidification.
Product Description
Copper mould tube is core accessories of mould for steel billet continuous casting machine, and highly related to the steel billet quality. Copper mould tubes are supplied in the shape of square, rectangular and round with sizes up to 16000 mm in casting radius with a wide selection of coatings, including Nickel and chrome coatings.
