The coal mining scraper conveyor is an important equipment used in the coal mining face. It mainly plays the role of carrying the shearer and coal transportation. Its performance is directly related to the stability of the entire production system of the face. Since the moving parts of the coal mining scraper conveyor are mainly transported by relative sliding, solving the wear problem of the coal mining scraper conveyor has always been the key to improving its service life and performance. In addition, the working face environment is harsh, and the coal water and sulfur in the coal will promote the wear of the coal mining scraper conveyor.
Using laser cladding technology is the best process for repairing coal mining scraper conveyor. This technology refers to pre-positioning of coating materials on the surface of the cladding substrate with different filler methods, and melts it and a thin layer of the substrate surface at the same time by laser irradiation, and forms a very low dilution rate after rapid solidification. The surface of the material is a metallurgical bonded surface cladding layer, which significantly improves the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical characteristics of the substrate surface. According to the material, working environment, and technical requirements of the coal mining scraper conveyor, select the corresponding cladding alloy powder and cladding process to repair it.
After our company performs laser cladding remanufacturing on the easily worn parts of the scraper conveyor, such as the middle groove and the transition groove, it can significantly improve the overall wear resistance of the scraper conveyor. The surface of the repaired scraper conveyor is wear-resistant and corrosion-resistant Compared with the traditional repair process, the performance is improved by 2-3 times, so that the functional components of the whole machine have reached the best match.
