| description | The invention aims to provide an alloy powder for medium-nickel/chromium infinite chilled cast iron roll laser surface alloying and an alloying technique thereof. The alloy powder comprises WC, TiC, Ni, Cr, Co, Si, Mo and Y2O3 powders. The invention also provides an alloy powdering technique which comprises the following steps: removing rust by sanding a roll surface to be treated, removing oil stains on the surface with an organic solvent, mixing the alloy powder and a varnish ethanol solution, uniformly spraying the mixed solution on the working surface of the roll to be treated, airing, scanning the roll surface with a laser so as to melt and mix the alloy powder and roll surface layer, thereby forming a laser alloyed layer, and the like. When the alloy powder and alloying technique are utilized to perform laser alloying on the medium-nickel/chromium infinite chilled cast iron roll, a superfine-structure alloy layer is formed on the working surface of the roll, thereby improving the microhardness and enhan |
