1. High strength wear-resistant steel is used. The results show that the strength and wear resistance of high manganese steel are better.
2. Build up wear-resistant and corrosion resistant alloy at the chain path according to a certain pattern to make the scraper and chain slide on the weld and separate from the direct contact with the medium plate parent.
3. The deep boriding treatment at the chain channel not only improves the surface strength and hardness, but also has good red hardness and corrosion resistance.
4. Apply new materials. MC nylon middle groove is adopted for light scraper conveyor; The heavy scraper conveyor adopts the method of steel plastic composite, and uses ultra-high molecular weight polyethylene as the lining to improve the wear resistance of the large machine, extend the service life, and reduce the friction coefficient.
5. During installation and operation, make the groove in the middle of each section as flat as possible.
