Description
2. Product features:The broken rate is less than 0.5%,
High impact toughness: the impact toughness is greater than 18J/cm2, and the 8-meter ball drop test is more than 20,000 times.
High overall hardness: surface hardness is 58-65HRC, bulk hardness is 56-63HRC, and the hardness gradient distribution is even.
No deformation: The steel ball is always not deformed, and does not lose its roundness.
The organization is compact, cost-effective, and cost saving is obvious.
3. Development trend: With the continuous research and development of raw materials and the continuous upgrading of production equipment in recent years, the application field has become more and more extensive, especially in semi-autogenous mills such as metallurgical mines and ball mills with a diameter greater than 2.5m, forging steel balls wear and tear. Low, low breakage, more obvious advantages compared to cast steel balls. As far as the current wear-resistant steel ball market is concerned, in wet grinding applications such as foreign metal mines, forged steel balls are generally used for grinding. In the domestic market, many cast steel balls are currently used, but the forged steel ball market is increasing year by year.
Precautions
Forged steel balls should be wear-resistant and wear-resistant materials, such as 60Mn and 65Mn of the national standard, and it is recommended to use steel produced by national super-large steel mills.
