B2 Steel Forging/Hot rolled Steel Ball Basic information on forging wear-resistant steel balls Material composition: C: 0.75 to 0.85; Cr: 0.40-0.60; Mn: 0.70 to 0.90; Ni: 0.25; P: .035; S: .035; Si: 0.17 to 0.37 Diameter: 20mm-150mm Surface hardness: core hardness: s60HRC Breaking rate: .5% Lost rate: .1% Impact value: s12J  The advantages of forging wear-resistant steel balls: 1, through forging can eliminate the metal in the smelting process produced by the casting state loose and other defects, optimize the microstructure, and because of the preservation of the complete metal streamlined, forging mechanical performance is better than the same material castings. 2, forging steel ball wear resistance is entirely dependent on the use of materials, sheng-sand wear-resistant steel ball using the steel produced by a large steel mill, good impact resistance, strong toughness, good wear resistance, not easy to break We use, forge and forge the method, is to heat the metal until the temperature reaches 1100oC (-50oC), the use of forging machinery to apply pressure on the metal billet, so that it creates a plastic deformation to obtain a certain mechanical properties, a certain shape and size forging solder ingres processing method. We use the country's large steel mills produced steel, the same is a material, in different steel mills produced the quality is also unequal, and the quality of forgings 80% depends on the quality of the material, such as the use of manganese chromium alloy steel, good impact resistance, strong toughness, good wear resistance, not easy to break. Forged steel balls are popular with users because of their cheap, economic durability, such as international mining giants Rio Tinto, BHP Billiton and Anglo Gold, which use forged steel balls. Forged steel ball size is precise, high roundness, high hardness, with mechanical properties. It is wear-resistant and does not deform and break easily. Can be fully reflected by the overall hardness of high, surface hardness up to 57hrc to 67hrc, volume and hardness up to 56hrc to 64hrc, hardness distribution, impact toughness greater than 12j/cm2, low breakage rate, anti-fatigue drop test more than 20,000 times, the actual breakage rate is not greater than 1%, close to 0. Production process: Custom raw materials - raw materials to the factory after the use of spectrometers to detect chemical composition indicators - metal detector to detect the inside of the round steel for dark injuries - testing qualified materials into the production workshop - into the automated hot-rolled steel ball production line - rolled into balls - sowarm - quenching - insulation - tempering - detection of impact toughness - Rock hardness test surface hardness - wire cutter cutting steel ball - detection core hardness - use of gold-phase tissue microscope detection of gold phase tissue - drop test bench detection steel ball anti-fatigue life - qualified packaging - delivery factory About the company Shandong Shengyu Grinding Ball Co., Ltd., is located in the beautiful Spring City Jinan City Zhangqiu District. In China is dedicated to the production of ball mill with forging and hot-rolled grinding steel balls and alloy grinding steel rods professional factory, steel ball annual output of 100,000 tons, steel rod annual output of 60,000 tons. More than 95% of the products are exported to more than 30 countries abroad, customers in Southeast Asia, Africa, Latin America, China and the world-renowned large mining companies as well as cement plants, thermal power plants and chemical plants have good business cooperation and their praise. At present, the company has the world's advanced level of forging and automatic rolling production lines 10, the production of diameter 15mm-200mm steel ball, with a fully automated heat treatment steel rod production line 2, the production diameter of 40-150mm, the length of 2-6 meters wear-resistant steel rods. The company's products in turn through the German tuviso9001 quality system certification, iso14001 environmental management system certification, ohsas18001 occupational health and safety management system certification and China's General Administration of Safety and Supervision issued a standardized certificate of safety production, because the company is the use of advanced technology and automated process production, The whole round steel is heated evenly at once to ensure that the quality and hardness of each steel ball produced are qualified. The company is well-equipped to test, has passed the sgs and bv two companies two-factor certification for the qualified standards plant. And has a first-class experiment and laboratory, and equipped with advanced testing equipment at home and abroad have spectrometers, hardness meters, microscopes, drop test machines, impact test machines, laser wire cutting machines, etc., to ensure that our products from raw materials into the factory to the production process and testing to the final shipment of each link has quality control assurance and traceability. Packaging of forged steel balls 1, tons of bags 2, tons of bags and trays 3, iron barrel 4, iron buckets and trays Ton bags are divided into two types: 1 ton/bag or 2 ton/bag The trays are divided into two types: one totwo or two to two. According to the customer can choose the above packaging method For more information please contact:
