PURPOSE:To improve uniformity and minuteness of coating in rolling rolls by flame spraying aggregated powder granulated with a WC series material and a self-fluxing alloy on the surface of a base metal. CONSTITUTION:The powder of WC series material and a self-fluxing alloy are granulated integrally by the ordinary spray granulating method to form the aggregation powder, and this powder is flame sprayed on the rolling roll 1 to form the flame sprayed coating layer. As the results of this spray method the required conditions as the rolling roll, i.e. the wear resistance, seizure resistance and thermal shock resistance are satisfied when loading conditions are considerably high. |
