Scraper conveyor has been used to convey materials, friction wear and corrosion wear are the main failure forms of the scraper conveyor. It is one of the most serious damaged equipment in coal mining production caused by wear and tear, the most important of which are middle trough, sprocket, chain, scraper, bearing and wheel gear in the reduction box.

According to the data and statistics obtained on site, the consumption of iron and steel materials in the coal mining machinery system is equivalent to 5 billion RMB annually. In addition, refers to the actual measurement and analysis, 30-40% power consumption was caused by friction and wear. Coupled with oil consumption, coal system economic loss caused by the abrasive wear will be more than 40 billion RMB per year.

In view of the wear failure severity huge economic losses, the applications of YaoYu CrC wear resistant steel plate effectively reduce and prevent the coal mining mechanical wear, thereby prolonging their service lifetime and realizes high output and efficiency of coal production.
