The middle groove of the coal mine scraper conveyor is washed away by coal gangue. The service life of the traditional high manganese steel middle groove is only 6 months, and it needs to be stopped for 12 hours to replace one section. The annual replacement cost of a single mine exceeds 3 million yuan. Daokedao melts WC Co alloy coating in the wear-resistant area of the middle groove, with a coating hardness of HRC65 and a wear resistance five times that of high manganese steel. After being applied in a coal mine in Shanxi, the service life of the central trough has been extended to 3 years, the annual replacement frequency has been reduced from 2 times to 0.3 times, the downtime for maintenance has been reduced by 84 hours, the coal production has increased by 42000 tons, and the income has increased by more than 10 million yuan. The bonding strength between the coating and the substrate reaches 550MPa, and there is no peeling after 1 million scraper impact tests, fully suitable for harsh working conditions in coal mines.
