High-chromium cast balls: A revolutionary force in industrial wear-resistant applications High-chromium cast balls, with their unique performance advantages, are becoming a significant force of innovation in the industrial wear-resistant field. This material forms a composite structure of martensitic matrix and chromium carbide hard phase through high chromium content, demonstrating a hardness of up to 60-65HRC, excellent impact toughness, and a wear rate that is 30%-50% lower than traditional materials. In the mining industry, it significantly boosts the efficiency of crushers by over 20%, and increases the recovery rate of concentrate by 5%-8%; in the cement production field, it can enhance the capacity of mills by 15%-25%, and increase the specific surface area of cement by 10%-15%. In recent years, innovations such as directional solidification technology and vacuum degassing processes have significantly improved the purity and microstructure uniformity of the material. Faced with increasingly strict environmental protection regulations, the industry is accelerating the research and development of low-chromium and environmentally friendly formulas, promoting electric furnace smelting + waste heat recovery systems, and reducing the energy consumption per unit product by more than 18%. In the future, through technological breakthroughs such as nano-modification and intelligent casting, it will achieve dual upgrades in performance and environmental protection, continuously providing green solutions for the industrial wear-resistant field.

Jinan Haoyang Casting and Forging Co., Ltd., relying on over 40 years of accumulation in the research and development of wear-resistant materials, recently launched a new generation of concave ball mills, which has attracted industry attention.

It can help reduce production costs for high-energy-consuming industries such as mining and cement. As a high-tech enterprise in Zhangqiu District, although the company is relatively small in scale (with less than 50 employees), it has continuously consolidated its industry position by virtue of the market reputation of its core products such as castings, forgings, and steel balls. This new product launch not only expands the product matrix but also highlights its "small but strong" technological innovation capabilities. In the future, the enterprise is expected to achieve greater breakthroughs in the high-end equipment manufacturing field through continuous technological iteration and high-quality services.

Recently, Jinan Haoyang Forging and Casting Co., Ltd. has drawn attention in the mining machinery and cement building materials fields with its independently developed hot-rolled steel ball technology. This veteran enterprise, which has been rooted in the casting industry for 14 years, holds multiple patents and certifications, with an annual output exceeding 100,000 tons. Its steel balls feature high hardness, wear resistance, and a full range of specifications with small roundness errors. The products are exported to over 20 countries, and cross-border orders are constantly coming in. New types of steel balls have filled the gap in the chemical industry. In the future, the company plans to invest 20 million yuan to expand production lines and optimize service plans, aiming to seize the high ground of global mining equipment technology.

Forged steel balls are wear-resistant grinding media produced through a high-temperature deformation process. Their production process mainly consists of two methods: rotary cutting roll forging and hammering. In terms of material selection, special alloy steels such as 60Mn, 65Mn or B2 are often used. After heating the steel rods to 1000-1100℃ in a medium-frequency heating furnace, they are deformed by an air hammer or roll forging machine to form the initial spheres 139. The forged steel balls need to undergo quenching and tempering treatment to achieve a surface hardness of HRC 56-67, with uniform hardness gradient both inside and outside, and possessing high wear resistance and impact toughness (impact value ≥ 12J/cm²), with a breakage rate of less than 1%. Compared to cast steel balls, forged steel balls have advantages such as smooth surface, dense structure, and low out-of-round rate (≤ 2%). Their service life can reach 2-5 times that of cast balls, and are particularly suitable for wet grinding environments in large-scale mines and cement plants 2410. The production equipment is trending towards automation, with energy consumption reduced by 30%-50%, resulting in significant cost benefits and becoming an ideal substitute for high-chromium cast balls 15. Currently, they are mainly used in large-scale grinding scenarios with a diameter of 110mm or above, and global mining giants such as Rio Tinto and BHP Billiton have widely adopted them 89.
