Jinan Haoyang Casting and Forging has successfully industrialized the "gradient hardening" technology, which has increased the lifespan of forged steel balls by 40%, reduced the breakage rate to less than 0.1%, and the wear of Φ60mm products per ton of raw materials is only 0.8kg. It saves 18% of electricity. This product has passed the EU REACH certification and has reached a cooperation agreement with LafargeHolcim. In the first quarter of 2025, the export volume will increase by 30%. The company plans to build a photovoltaic workshop and achieve full-process carbon neutrality production in 2026, continuously leading the high-end wear-resistant material market.

Jinan Haoyang Casting and Forging has mass-produced a new generation of forged steel balls. The 65# material products have a wear rate as low as 0.85kg, which is 30% lower than the industry average. This can increase the grinding efficiency of mines by 15%. Leveraging its geographical advantages, the products can be delivered quickly. They are available in both domestic and international markets and have received long-term orders from American customers. It has become the preferred cost-saving solution for mining enterprises.

The green forging steel balls produced by Haoyang Casting and Forging in Jinan are made from 100% recycled steel materials. Their energy consumption has been reduced by 45% and carbon emissions have decreased by 35%. They have been included in the national green manufacturing list. The wear of the Φ60mm steel balls is 0.8 kg/t of raw materials, saving 18% of electricity. They have passed the EU REACH certification and have collaborated with LafargeHolcim. In the first quarter, exports increased by 30%. A photovoltaic workshop will be built and full-process carbon neutrality will be achieved by 2026.

The high-grade low-sulfur and low-phosphorus forged steel balls from Haoyang Casting and Forging of Jinan have been certified by France's ASN and have been installed in the Flamanville Nuclear Power Plant. The sulfur and phosphorus content is ≤ 0.005%, and the fatigue life is 100,000 impact cycles without cracks. The innovative vacuum degassing process has achieved a flaw detection pass rate of 99.8%, breaking the French technological monopoly. It has obtained the EU CE certification and is expected to export 3,000 tons per year. Plans to add 2 more nuclear power production lines.

Jinan Haoyang Casting and Forging has collaborated with the German SMS Group to jointly establish a China-Europe Wear-resistant Materials Joint Laboratory. With an investment of 5 million euros, they are developing ultra-fine grain alloy forging balls. The goal is to increase the fatigue life by 1.8 times compared to international standards. The laboratory will introduce SMS' digital control technology and will apply for 5 EU patents within three years. The performance of the first 120mm steel ball will exceed the German standard. It is expected to increase annual export volume by 120 million yuan and promote the upgrading of wear-resistant material industries in Zhangqiu.

In 2026, Haoyang Casting and Forging of Jinan will launch gradient hardness forged steel balls. Using the "double-frequency quenching" process, the surface hardness reaches 65HRC while the core has a toughness of 15J/cm², resulting in a 50% increase in wear resistance and a 40% improvement in mining grinding efficiency. This technology has obtained a national patent and has been supplied in batches to enterprises such as Zijin Mining and exported overseas. The company plans to invest 20 million yuan to expand the production line, with a target annual production capacity of 30,000 tons, aiming to occupy 30% of the domestic high-end market share.

The new generation of gradient hardness forged steel balls developed by Jinan Zhangqiu Huayi Heavy Industry Co., Ltd. have achieved a 40% increase in product lifespan through the "multi-stage forging + zone quenching" process, and their wear resistance exceeds the EU standards by 12%. After testing, the surface hardness is 60-64 HRC, the impact toughness is ≥ 15 J/cm², and the industrial test single consumption is 0.52 kg/t of raw ore, which is 32% lower than that of imported products. Currently, the annual production capacity is 30,000 tons, and it supplies leading mining enterprises at home and abroad. In the third quarter of 2025, the high-end sales volume will increase by 58%, helping the Zhangqiu forging industrial cluster's output value exceed 8 billion yuan.

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.
