Quenching and tempering process for forging high-hardness wear-resistant steel balls
Forged steel balls are wear-resistant grinding media formed by carbon steel or alloy steel through forging processes and are widely used in ball mills in fields such as mining and metallurgy. Their production process includes steel bar cutting, medium-frequency heating, air hammer forging, and quenching and tempering treatment, ensuring a surface hardness of 58-65 HRC, good toughness in the core, and a breakage rate of less than 0.5%. Compared to cast steel balls, forged steel balls have higher density and impact resistance, a lifespan that is 2-5 times longer, and a lower price. Currently, domestic enterprises enhance efficiency through automated production lines, and their products are exported to regions such as Europe, America, and Southeast Asia, with an annual growth rate of over 12%. In the future, new material research and intelligent production will drive further industry upgrading.
