Abrasion-resistant Grinding Media Balls Have Improved Abrasion And Breakage Rate

The temperature between each link and each point in the wear-resistant steel ball production line can be displayed and controlled on the microcomputer display screen. The steel ball hardened layer is hardened. The steel ball that has been heat-treated on this production line is more heat-treated than ordinary wear-resistant steel balls. It is more uniform, the hardness of each part of the steel ball is uniform, which completely eliminates the internal response problem and the problem of oxide scale of the different hardness of each part of the heat-treated steel ball, and further reduces the wear and breakage rate. 2: The hardness of the steel ball breaks through the tradition. The traditional heat treatment of the steel rod is to plasma-cut the first-class round steel of a large state-owned enterprise steel factory with a hardness of about HRC10-15, and enter the dedicated independent production line for high-temperature forging heat treatment to directly increase the hardness Or stepwise increase to higher hardness, and then use heat treatment technology to process to the hardness range required by the customer again, and then undergo high temperature tempering-heat preservation-quenching. This is the key to Houde brand steel balls with high hardness, uniform hardness, and non-zero crushing. . 3: Main features of forged steel balls: Surface hardness: HRC56-65 (different specifications and hardness are different). Heart hardness: HRC54-62 (different specifications, hardness is different). Impact value: Ak.17 j/cm Fragmentation rate: 25mm-80mm0.5%, 90mm-140mm1% (the actual use of the crushing rate is almost no crushing), out of roundness.
