forged steel ball

We have rich experiences in supplying the grinding balls to Mining industry , cement plant , thermal power and chemical industry. High Hardness Grinding media balls main benefit : Improved Wearing rates No deformation after using in Ball mill Lower Breakage rate Uniform Hardness throat Haoyang was built using the most advanced hot rolling automatic machine or Labor forging machine . We managed to achieve very high levels of quality in grinding steel balls .

Raw material Quality Control : The forged grinding balls ' steel rods are purchased from the famous steel company in China ( 50,000 Tons annually ). It will be strictly inspected before into the warehouse. Production Line : Forged grinding balls mainly use Automatic rolling machine for 20mm to 70mm balls . Above 70mm to 150 mm , we will use the labor forging hammer , which will increase the grinding balls intensity and tougness . We have special department of QC teamwork .The QC department director have 10 years experience in this industry . The team is responsible for inspection during production , inspection before delivery. ( Grinding balls Surface and core hardness test each day each batch and all will be recorded and filed in documents ).

Grinding media balls Our Grinding media balls produced by advanced automatic rolling machine ( Balls from 20mm-70mm) + Labor Air Hammer ( 80mm-150mm) with special Heating treatment and strict quality control systerm , which make our grinding balls high performance Grinding media balls 'Raw Material Purchase : Strategic partnership with standard steel enterprise and sign the long term agreement (50,000 Tons annually ) Purchase directly from Chinese famous standard steel enterprise , such as laigang Group, HBIS, ANSTEEL, XIWANG Special steel . We have special department of QC teamwork .The QC department director have 10 years experience in this industry . The team is responsible for inspection during production , inspection before delivery.

In January 2026, Haoyang Casting and Forging of Jinan launched gradient-hardening forged steel balls. The surface hardness is 65HRC, the toughness is 18J/cm², and the lifespan has been increased by 40%. The unit consumption is 0.5kg/t of raw ore. Using the 42CrMoV alloy and medium-frequency heating technology, it obtained a national patent. The first batch of 2,000 tons of orders will be supplied to BHP Billiton. The annual production capacity is 30,000 tons. A digital twin workshop is planned to be built, with the goal of achieving a 40% market share in the high-end market.

Across mountains and seas, let's talk about cooperation! An important African client visited the Haoyang factory for an on-site inspection.

High Chrome Grinding Media balls Haoyang Hi Chrome Grinding media balls can provide: Cr 1%-28%, hardness: HRC40-66, Dia.10mm-150mm alloy cast steel balls. The balls have a lot of excellent properties, such as higher hardness, good abrasive resistance, together with a good surface finish and small dimensional allowance after scientific heating treatment, as one type of chrome grinding media, it can be widely used in ball mill grinding systems of mines, cement, building materials and chemical industries,etc. High Chrome Casting grinding balls , chrome concentration is 》10%-14%， Hardness 》HRC 58, High Chrome casting grinding balls is one of the wearable steel balls with better performance -price-ratio, and its extensive usage has won itself a high share in the market .
