[0002] At present, the scraper conveyor is an important part of the coal transportation machinery in the mine, and the middle trough is the most important component of the scraper conveyor. The middle trough is the main channel for coal transportation, and it bears the severe friction and impact of coal, scrapers and chains during transportation. The failure of the scraper conveyor is mostly caused by the wear and breakage of the middle trough. Therefore, the production quality of the middle trough directly determines the service life of the scraper conveyor. Therefore, wear-resistant process treatment is required during the production process of the middle trough of the scraper conveyor. Wear-resistant surfacing is a green and environmentally friendly welding technology that surfacing a layer of alloy with good wear resistance and high hardness on low-priced carbon steel or metal materials.
