The repair of copper mould tube

In the process of continuous casting, Zn, S, Cd and F in molten steel diffused to the surface of copper tube through cracks and creases of the chromium plating layer, resulting in hot brittleness of the mould copper tube matrix, which resulted in the formation of a large number of micro-cracks on the surface of the mould copper tube matrix, resulting in the further expansion of cracks in the chromium plating layer. Additionally, crystallizer copper tube is anodic coating, chrome plating layer in the molten steel for a long period of time under the influence of chemical corrosion, thermal erosion, chromium plating layer occurs pulverization and peeling phenomenon, its abrasion performance dropped substantially, chromium plating layer in the process of casting billet are quickly destroyed by the wear and tear so wear resistance of chromium plating layer is very limited, short service life.

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