Used for steelmaking High mechanical stability Continuous Casting Mould Tube for CCM

Function of Mould Copper Tube-Characteristics of Mould Copper Tube

Mould copper tube plays a very important role in industrial manufacturing. For example, mould copper tube is used in the manufacture of ships, ships, automobiles and refrigerators. The main characteristics of copper pipe material for high-efficiency continuous casting mold are: high thermal conductivity, high recrystallization temperature, thermal fatigue resistance, high strength, good wear resistance and long service life. The main characteristic of copper pipe material for high-efficiency continuous casting mold is that the copper pipe material has the best comprehensive performance.
The characteristics of explosive molded crystallizer copper tube are as follows: the tapered crystallizer copper tube can be manufactured by copying or pressure forming with inner core and outer die. Copying will destroy the organizational structure of copper and affect its service life. Processing complex taper requires special processing equipment, which increases the manufacturing cost. Pressure forming will lead to large head cutting and tail cutting, and the yield of copper is low. The copper tube of crystallizer formed by explosion can be made into multi-taper and small round angle of inner cavity, which is especially beneficial to the repair of discarded old crystallizer.

Function of Mould Copper Tube-Performance of Mould Copper Tube

In order to improve the wear resistance of chromium coating and prolong the service life of crystallizer copper tube, a nickel-cobalt alloy coating with a thickness of 0.4-0.5 mm was added between the inner surface of crystallizer copper tube and chromium plating layer as a transition layer. Therefore, it is called Ni-Co alloy-hard chromium coating. Composite copper-plated pipe for short. The metal contents are as follows: the hardness of the coating is 300—600HV.
Nickel-cobalt alloy coating has good chemical corrosion resistance, thermal corrosion resistance and wear resistance. It not only blocks the diffusion of Zn, S, Cd
