What are the properties of the crystallizer copper tube

In order to improve the wear resistance of chromium coating and prolong the life of mold copper tube, a transition layer between the inner surface of mold copper tube and chromium plating layer was added into the nickel-cobalt alloy coating with thickness of 0.4-0.5mm.  So called nickel-cobalt alloy - hard chromium plating.  Composite copper tube for short.  Metal content: coating hardness of 300-600hV.

Nickel-cobalt alloy coating has good chemical corrosion resistance, heat corrosion resistance and wear resistance.  It not only blocks the diffusion of Zn, S, Cd and F in molten steel on the inner surface of the copper tube of mold, but also acts as a binding agent between the inner surface of the copper tube of mold and the chromium plating layer, which greatly improves the wear resistance of the chromium plating layer.  In addition, the nickel-cobalt alloy coating can replace the chromium coating after the chromium coating is worn, thus extending the service life of the mold copper tube.

    In continuous casting, low corrosion resistance often occurs, which directly leads to uneven composition and will eventually affect the smelting quality. In or
