The peak production period of the mines in May, combined with the summer flood season, presented a challenging test. However, Jinan Haoyang Casting and Forging produced steel balls with a hardness of HRC 58-62 and an impact toughness exceeding the industry standard by 30% through the use of Cr-Mo alloy material and precise rotary forging technology. The optimized surface wear-resistant layer has extended the service life by 45% in wet grinding scenarios, making it a core wear-resistant component for stable production and efficiency improvement in mines in Jiangxi and Guangxi, among others.
