In 2025, the performance breakthrough of the forged steel balls produced by Haoyang in Jinan, Shandong Province, is not only a model of the integration of materials science and intelligent manufacturing technology, but also marks a crucial leap for China's forging industry from "scale expansion" to "quality leadership". The industrialization implementation of its technological achievements will reshape the global wear-resistant material market landscape, provide core foundation components support for the high-end equipment manufacturing industry, and demonstrate significant economic value and strategic significance.

Forged steel balls and cast balls are two of the core media in the industrial grinding field, and their processes and performance differ significantly. Forged steel balls are made of low-carbon alloys, high-manganese steel, or rare earth chromium-molybdenum alloys, and are formed through heating and forging. They have the characteristics of smooth surfaces, strong impact resistance, and high toughness, with a breakage rate of less than 1%. They have excellent wear resistance and are particularly suitable for wet grinding environments in mines and power plants. Their prices are economical and are widely adopted by international giants such as Rio Tinto and BHP Billiton. Cast balls are made from low-chromium, medium-chromium, or high-chromium cast iron and are formed by pouring. Although high-chromium cast balls have high hardness (HRC 60+) and excellent wear resistance, their toughness is poor. Balls with a diameter over 3 meters are prone to cracking in ball mills, and their costs are higher. They are mostly used in dry ball mills in the cement industry. The core difference between the two lies in: The forging process optimizes the metal flow structure, and the anti-cracking performance of forged steel balls is 5-10 times that of cast balls. However, cast balls rely on increasing chromium content to enhance wear resistance, but at the expense of corrosion resistance. When selecting, it is necessary to consider the working conditions (dry/wet grinding, equipment scale), cost, and performance requirements. For example, large mines prefer forged steel balls, while cement plants tend to use high-chromium cast balls.

The Qingdao Mineral Expo is a significant exhibition related to the mining industry, where numerous enterprises usually showcase their products, technologies, and engage in business negotiations. If Jinan Haoyang Casting and Forging participates, its performance may be influenced by various factors such as the innovativeness and quality of the displayed products, the business negotiation capabilities of the enterprise, and the promotional efforts. If you want to know the subsequent developments, you can pay attention to the official information of the exhibition, industry media reports, and the enterprise's own updates.

【Jinan Haoyang Forging and Casting Deepens Cooperation with Chile's CODELCO】On June 30th, the technical team of Chile's CODELCO visited Jinan Haoyang Forging and Casting, focusing on inspecting its fully automated forging workshop and quality inspection system, and observing the entire production process of 5.5-inch high wear-resistant steel balls in real time. During the meeting, Haoyang showcased cases exported to over 20 countries and its B2-level special alloy steel ball technology. Its HRC62 hardness and 1% breakage rate indicators were recognized by the foreign party. Based on the fulfillment of a 2,000-ton order, the two parties signed the "Strategic Supplier Framework Agreement". Haoyang will customize a full series of 3-6-inch forged steel balls for CODELCO's expansion project in 2026, with an estimated annual supply volume of 150,000 tons. General Manager Zhang Hua of Haoyang disclosed that the company is leveraging the geographical advantages of Zhangqiu District to build a bonded warehouse and plans to achieve direct delivery of 72-hour global urgent orders. As an enterprise deeply engaged in wear-resistant materials for 18 years, Haoyang has 12 forging production lines, with an annual capacity of 80,000 tons. Its products have passed SGS and ISO9001 certifications and serve international projects such as Chile's national copper mines and Australia's FMG.

Technological breakthrough Jinan Haoyang Forging & Casting has developed rare earth alloy steel balls with a hardness of HRC 62-65 and a 20% increase in toughness by leveraging 15 patented technologies. It has achieved a "hard exterior and tough interior" through AI temperature-controlled gradient quenching technology and reduced energy consumption by 35% with an electric arc furnace short process, meeting the EU carbon tariff standards. As a result, it has successfully won a five-year billion-yuan order from Rio Tinto Group. The intelligent production model The 20-acre "dark factory" achieves an annual production capacity of 50,000 tons through 90% automated production lines, requiring only a 50-person team. The flexible customization system supports a 72-hour switch to produce all specifications of steel balls ranging from Ф20 to 150mm, meeting the demands of multiple fields such as mining and cement. Zero-carbon Strategic Planning It is planned to launch the "Super Grinding Ball Project" in 2025, building the world's first zero-carbon wear-resistant materials park in Zhangqiu. The project will integrate photovoltaic smelting and hydrogen energy heat treatment technologies to drive the green transformation of the industry. Market Impact This case, through three major highlights - technological disruption (patented process), model innovation (intelligent micro-factory), and global orders - combined with the hotspots of carbon neutrality and Industry 4.0, strengthens the positioning of "small but precise" enterprises, providing a benchmark for the intelligent transformation of traditional manufacturing.

Jinan Haoyang Forging and Casting has launched a new generation of high-chromium alloy wear-resistant steel balls, leading the upgrade of wear-resistant material technology. (Jinan Haoyang Forging and Casting Co., Ltd. announced today that it has launched a new generation of high-chromium alloy wear-resistant steel balls. The balls are made of B2/B3 high-chromium material and processed by vacuum casting and special heat treatment. Their hardness reaches HRC62-65, and the impact toughness has been improved by 30%. The breakage rate is less than 0.3%. This product is specially designed for the mining, cement and power industries. It can significantly reduce equipment maintenance costs and extend the service life by more than 50%. Currently, the product has been purchased in batches by many large domestic enterprises and exported to Southeast Asia and African markets. The company also announced the research and development plan for nano-modified high-chromium balls, continuously promoting technological innovation in the industry.)
