Henan shuangzhi machinery equipment co., LTD.

The scraper is the conveying medium of the scraper conveyer to transport coal. The main function of the scraper is to make the chain belt to unload the coal from the nose to the tail. Scraper conveyor scraper quality improvement can greatly improve the production efficiency.
At present, the common scraper material in the market is: 27SiMn, 40Cr, 45#, 40Mn2
The scraper is formed through multiple quenching die forging, and the scraper is a piece of molding and three bolts. Scraper scraper new scraper force degree and tensile strength is high, large coal, low cost. Scraper is not easy to store in wet, high temperature and chemical corrosion place, such as in the above conditions of storage will cause rust, heat expansion and cold shrinkage, corrosion, the storage method on the service life is also a certain impact. When the scraper rupture may be due to the downhole environment over gangue and other circumstances do not break.
