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.
