"Technological Breakthrough in Special Steel Balls: How High-Chromium Balls Achieve 'No Breakage and No Deformation'?"
Jinan Haoyang Casting and Forging Co., Ltd. leads the wear-resistant materials industry with its innovative hot-rolled steel ball technology. Recently, the company has drawn widespread attention in the mining machinery and cement building materials sectors with its independently developed hot-rolled steel ball technology. As a well-established wear-resistant materials manufacturer in Zhangqiu District, Shandong Province, the company has been deeply engaged in the casting field for 14 years, holding 15 patents and 2 industry qualification certifications, with an annual output exceeding 100,000 tons.
The company's B2/B3 grade steel balls, manufactured on fully automated hot-rolling production lines, have a hardness of 58-66HRC and an impact toughness of ≥12J/cm². They feature high wear resistance and a low breakage rate. The product range covers all specifications from 20 to 160mm, meeting the grinding requirements of various scenarios such as mines, power plants, and cement factories. Certified by ISO9001 and subject to strict quality inspection processes, the roundness error of the steel balls is controlled within 0.5%, and their wear resistance is 30% higher than that of traditional cast balls.
The market performance has been outstanding. Currently, Haoyang Cast and Forging's hot-rolled steel balls have been exported to over 20 countries including South Africa, Australia, and Russia. The company has participated in three domestic and international bidding projects and has achieved multiple cross-border orders on the Alibaba platform. Relying on the industrial cluster advantages of Zhangqiu District, the company has established a full industrial chain service from raw material procurement to logistics distribution. The "wet grinding resistant medium chromium steel balls" launched in 2024 have filled the gap in special grinding materials for the chemical industry.
Future Outlook
Chairman Chen Jinfu stated that the company plans to invest 20 million yuan to expand the intelligent hot-rolling production line, further optimize the "grinding materials + equipment matching" solution, and help Chinese manufacturing seize the technological high ground in the global mining equipment field.
