The copper tube of the copper mould tube is the heart expansion of the continuous casting machine. Its quality directly determines the quality of the slab and the amount of steel. The service life of the copper tube of the mold depends on the equipment process and management level of the steel plant, and also depends on the crystallization. The material of the copper tube and the manufacturing level of the copper tube.

At present, the copper tube made of phosphorus deoxidized copper and silver copper is widely used in China. The material of chromium zirconium copper has high strength and hardness, good electrical conductivity, thermal conductivity, and mechanical properties far higher than the currently used copper mould tube.
