***Description of forged grinding rods:
The steel forged rods is a kind of high hardness,wear-resistant steel products,which is developed ,researched and manufacturered by Huamin steel ball company alone.The forged steel bars can be used for rod mill in many areas,such as mining,chemical,cement,power plant industry and so on.
***Specifications forged grinding rod:1) Size: Dia. 40 - 120mm, Length 2000-6000mm2) Hardness: HRC 45-553) Chemical elements(%):C: 0.48-0.85, Si: 0.15-0.37, Mn: 0.7-1.0, P: 0.035 MAX, S: 0.035 MAX ***Features of forged steel rod: 1)High Hardness2)high impact toughness3)low breakage4)no deformation ***Raw MaterialAs we all know, the quality of product mainly depends on raw material, so our raw material is customized from the Chinese famous steel factory, which can guarantee the quality.
***Applied fields:Used for rod mill such as cement plant, electric power plant, mine, quartz sand plant, silica sand plant, sand aerated industry, coal chemical industry, gas concrete plant, etc. ***TestingOur lab is equipped with advanced testing machine to strictly control the quality of the product. ***PackageWe bundle the finished products according to the customers' requirements.standardization identification, clean production enterprise certification.
Features and Advantages of Grinding Steel BarConcentrating on wear-resistant grinding material for 30 years, Shandong Huamin Steel Ball Joint-Stock Co., Ltd is one of the largest grinding rod manufacture in China. We manufacture the product with the length of 2m to 7m and the diameter of 40mm to 140mm. The data is just for reference. The product can also be customized. After years of research and development, we finally develop the new-type steel grinding rod successfully. The newly developed product is characterized by low wear, unique chemical composition, high hardness of 45HRC to 55HRC, and strong toughness. Meanwhile, via the quenching and high temperature tempering treatment, the internal stress is removed. The product has good straightness, and won't break, bend and come out with two tapering ends. The economic benefit is much in evidence. a. The blanking of the steel grindng bar is implemented via the sawing machine. The dimensional tolerance would adide by the requirements of the order. After the implementation of blanking, the two ends of the raw material are polished into the R arc via the polishing machine. b. The surface of the product for the rod mill cannot have the crack, overburning and fissure visible to the naked eyes.c. The nonstraightness of the product is less than 0.2%. The diameter tolerance ranges from +0mm to -1.5mm. The length tolerance is fro +0mm-25mm. The fracture should be less than 3%.
