Investigation On Hardness Of Metal Matrix To Composite-alloy Grinding Roller Of Wearing Resistance

The contents of this paper research mostly include abrasion fault analysis of grinding roller and different grain size of tungsten carbide effect on abrasive resistance of the composite alloy. Firstly, analyze under the practically run in the power plant abrasion fault of the grinding roll. Secondly, choose the sample component, as different particle match of tungsten carbide and specifically heat treatment craftworks of solution and aging manufacture test piece, watch metallurgical structure of the test piece and do the tests of hardness and tension, at last do the abrasive wear test on the dynamic load abrasive wear test machine, analyze test datum, From the test data, conclusions are arrived that the hardnees of Composite-alloy can be improved and wear-resistance be better by adding Cr and other elements according to a given ratio. This paper also research the technology to improve the intensity between Composite-alloy and basebody. Yu Changcheng (Thermal power engineering) Directed by prof. Bao Zhiyong, Huang Baohai...
