Jinan Haoyang Forging & Casting Co., Ltd.: Innovating forging ball technology to drive the upgrading of the grinding medium industry
Recently, Jinan Haoyang Casting and Forging Co., Ltd. (hereinafter referred to as "Haoyang Casting and Forging") has launched a new generation of high-performance forged balls. Through the integrated process of "forging + isothermal quenching", the service life of the products has been increased by 35%, and the wear resistance has exceeded that of traditional cast balls by more than 15%. This has attracted widespread attention from the mining and construction industries. This series of forged balls covers a full range of specifications from 20mm to 150mm. After being tested by the National Quality Supervision and Inspection Center for Casting and Forging Machinery, the surface hardness reaches 58-62 HRC, the impact toughness is ≥ 12J/cm², and the comprehensive performance has reached the international advanced level.
As a specialized and high-tech enterprise in Shandong Province, Haoyang Casting and Forging has been deeply engaged in the field of forging balls for 15 years. It has 6 intelligent production lines and an annual production capacity exceeding 20,000 tons. This new product uses 42CrMo alloy material and medium-frequency induction heating technology. Through the "forging - residual heat quenching" process, it achieves dual improvements in grain refinement and hardness uniformity. "In the industrial trial at a certain iron mine in Shanxi, the single consumption of our 80mm forging balls dropped to 0.6 kg/t of raw ore, which was 28% lower than that of imported products," said Engineer Li, the director of the company's R&D department. This technology has applied for 3 national patents, among which "a method for preparing gradient hardness forging balls" has been granted an invention patent.
At present, the forged balls produced by Haoyang Forging have been supplied in large quantities to leading enterprises such as Zijin Mining and Tongling Nonferrous Metals, and have also been exported to major mineral resource countries like Australia and Peru. In the third quarter of 2025, the company's sales of high-end forged balls increased by 22% year-on-year, and the export volume exceeded 8 million US dollars. The general manager of the company, Chen Jinfu, disclosed that the next step will be to invest 30 million yuan to build a digital twin forging workshop, with the goal of increasing the market share in the high-end market to 50% by 2026.
