How to judge the wear resistance of wear resistant steel ball

  & nbsp; & nbsp; & nbsp; & nbsp; The use value of wear-resistant steel ball is very high. If you buy a good wear-resistant steel ball, it will not only take a long time to use, but also avoid a lot of trouble. After years of development, the company has become a large-scale wear-resistant material enterprise in China, with an annual production capacity of about 50000 tons of wear-resistant materials. According to the statistics of China Foundry Industry Association, in 2009, 2010 and 2011, the production and sales volume of wear-resistant casting products of the company ranked first among the grinding ball and grinding section products of wear-resistant materials in China. Since its establishment, the company has carried out in-depth research on the application technology of wear-resistant castings, digested, absorbed, used for reference and innovated the advanced technology at home and abroad, and developed the production lines of mechanized sand coated metal mold casting balls and stacked box tandem casting, which can produce all kinds of wear-resistant, heat-resistant and corrosion-resistant high-quality castings in strict accordance with astjis, dibs and other international standards. In addition, the company has continuously increased R & D investment, and obtained 46 national patents, including 12 invention patents, 12 utility model patents and 22 design patents; And successively participated in or presided over GB / t17445-200gb / t8263-20jc / t691 & amp; mdash; 2010 and many other national or industry standards, established the company's technical advantages in the industry. The company mainly produces high chromium alloy casting ball (high chromium ball), high chromium alloy casting section (high chromium section), low chromium alloy casting ball (low chromium ball), low chromium alloy casting ball section (low chromium forging), multi alloy casting ball (medium chromium ball), multi alloy casting ball section (medium chromium section), lining plate, hammer head and other different series of wear-resistant products. The same is wear-resistant ball, the price of steel ball is relatively high, so we must pay special attention to it. Specifically, how to judge the wear resistance of wear-resistant steel ball? Here is a detailed introduction& nbsp; & nbsp; & nbsp; & nbsp; & nbsp; Wear resistant steel ball generally needs the hardness and crushing rate of steel ball to judge its wear resistance. This kind of judgment is very accurate, so that the steel ball with high wear resistance can be bought when it is used, and it can be used for a longer time. The hardness of steel ball is tested by Rockwell hardness tester, and the Rockwell hardness of wear-resistant steel ball can reach above hrc58 after being heated by oil quenching process. If the hardness of the steel ball without heat treatment is about hrc45, it is not very durable, so we must pay attention to it. The higher the hardness of the ball, the better the wear resistance, which should be noted& nbsp; & nbsp; & nbsp; & nbsp; When the steel ball is broken, the ball dropping tester and impact test are used to prove that if you want to test the results more accurately, you can clear the warehouse and weigh the steel ball after use, so that you can easily judge whether the steel ball is wear-resistant or not with a comparison before and after use. Steel ball general wear-resistant price is relatively high, if it is more, the price will have a certain discount.
