Description

[0002] Currently, scraper conveyors use sleeve roller chain conveying devices, which are not resistant to high temperatures or wear, are easily damaged, have short service life, and high maintenance costs. Some use forged chains, where the forged chain and scraper chain links are integrated, and the chain is in direct contact with the scraper conveyor base plate. The conveying industry typically uses forged chains as the traction chain for conveying equipment to transport high-temperature and high-abrasion materials. To overcome the adverse effects of high-temperature and high-abrasion materials on the chain, in addition to requiring the chain itself to have high strength and wear resistance, it is also imperative to reduce chain wear from a structural perspective.
