Scraper Conveyor Sprocket Material Organisation and Wear Resistance Analysis
Based on the domestic scraper conveyor sprocket relies on the imported status quo,with the American imported sprocket and German imported sprocket as the object of research,respectively,in the respective surface and core sampling,analysis of the chemical composition of different sprocket samples of different positions,using XRD diffraction analysis technology,completed the physical analysis of each sample,through the composition and physical analysis,the two kinds of imports of sprocket products are used in optimizing the organisational Through the composition and physical analysis,it is concluded that both imported sprocket products adopt the method of organisation optimization to improve the wear resistance of sprockets.After that,the microstructure of different specimens was analysed,and it was concluded that the sprocket material includes hardened layer,transition zone and matrix,and there is a cryptocrystalline martensite to tempered solitite transformation from the outside to the inside,which ensures the hardness and wear resistance of the surface layer of sprocket and at the same time,the core of sprocket has a good toughness,which is able to satisfy the reliable operation of sprocket under the condition of impact.
