Zibo HITECH Material Co., Ltd can produce various copper mould tubes, including square copper tubes, rectangular copper tubes, round copper tubes, non-standard copper mould tubes and copper mould plates.
Copper moulds have played an important role in the development of the continuous casting process. Their function is to receive the molten steel and to allow rapid heat transfer from the steel to the cooling water to enable quick solidification. 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.
