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.

Jinan Haoyang Forging & Casting Co., Ltd., as a benchmark enterprise in the field of wear-resistant materials in China, has been deeply engaged in the industry for over 50 years. It focuses on the research and production of high-chromium alloy forging balls. The product diameters range from 20 to 150 mm, with uniform hardness gradient (core-to-surface difference ≤ 2HRC), a crushing rate of less than 1%, and a wear resistance that is 30% higher than that of cast balls. The energy-saving efficiency reaches 15%-20%, and it complies with the ISO14001 environmental protection standard. The company's annual production capacity is 50,000 tons. Its products are exported to over 20 countries, generating over 6 million US dollars in annual foreign exchange earnings. In the future, it plans to invest 50 million yuan to expand the intelligent production line, introduce an automated detection system, and increase the production capacity to 100,000 tons. It will also collaborate with universities to develop special alloy steel balls, focusing on expanding the high-end market in Europe and continuously leading in technological innovation and green manufacturing of wear-resistant materials.
