The ball heating and hardening process is fully automatic. The machine is equipped with an alarm system, which can clearly tell the operator the working cycle and machine failure information.Quenching process: grinding ball - grinding ball into the furnace - preheating - heating - insulation - pushing ball out - quenching (oil or gas) - grinding ballTempering process: ball loading (original or quenched)- Push the ball into the furnace - heating - push the ball out - packaging(2)Forged/Rolling Steel Ball·Smooth surface:A smooth surface is a characteristic produced by forging technology, with no defects in the surface of the ball, nor deformation or out of roundness. This amplifies the grinding effect of the balls on the ore for an optimum performance.·Internal tightness:Since these balls are forged from round bar steel, internal and external deviations, are non-existent. Forged balls have a high internal density and high fine particle degree, which enhances the drop resistance and the impact toughness of these balls, thus vastly reducing the breakage rate of a forged balls.·Suitable for wet grinding:Our forged balls are comprised of high-quality alloy steel, together with new efficient anti-wear materials, independently developed by our company. By matching the alloying element with rare elements, and by controlling the chromium content, the corrosion resistance of the balls is greatly improved; during wet grinding procedures, trivalent chromium oxide, forms a protective oxide film of chromium and iron which hinders the breakage of the ball and/or eases the reincorporation of the detached particles to the film itself. As mines commonly use a wet grinding process, this forged ball becomes even more suitable.·In SAG Mill operations:Large balls with a diameter of 125-150mm not only reduces unit consumption, but also increases handling capacity.Principal BenefitsWide range of media sizesConsistent, high quality for all media deliveriesLonger grinding media life·Diameter tolerance and roundnessDiameter(mm)2025304050606570758090100110120125130140150Tolerance(mm)±1±2+3,-2+4,-3+5,-4Roundness(%)≤1≤2≤3≤4≤5·Chemical compositionBrandC(9%)Si (%)Mn (%)G(%)Cu(%)Mo(%)P(%)S(%)Ni(%)HF-C450.42-0500.17-0370.50-0B00-0250-0250-0300-0.0350-0.0350-0.30HF-50Mn0.48-0.560.17-0370.60-1.00-0250-0.250-0.300-0.0350-0.0350-0.30HF-60Mn0.57-0.650.17-0370.70-1.00-0250-0.250-0.300-0.0350-0.0350-0.30HF-65Mn0.62-0.700.17-0370.90-1200-0250-0250-0.300-0.0350-0.0350-0.30HF-Q30.65-1.00.17-0.800.70-1200-0250-0250-0.300-0.0350-0.0350-0.30HF-40Cr0.37-0450.17-037050-0.80.80-1.10-0250-0.300-0.0350-0.0350-0.30HF-42CrMo0.38-0.450.17-0370.50-0800.90-120-0.030.15-0250-0.0350-0.0350-0.30HF-70Cr20.65-0.750.20-0300.75-0900.55-0.700-0.250-0.300-0.0300-0.0300-0.30HF-B20.70-1.00.17-0370.70-1200.40-0800-0250-0.300-0.0350-0.0350-0.30HF-B30.58-0.66120-200.65-0B00.70-09000-050-0.300-0.0350-0.0350-0.30HF-B60.75-0.85020-0.400.90-1.00.85-0950-0250-0.300-0.0350-0.0350-0.30HF-B6A0.82-0.95020-0.40092-1020.80-0950-0250-0.300-0.0350-00350-0.30HF-B70.35-0400.17-0370.7-0809-1.00-0.250-0300-0.0350-0.0350-0.30HF-BU0.95-1.050.17-03709-1.100.40-0600-0.150-0050-0.0350-0.0350-0.30HF-GCr150.95-1.050.15-035020-040130-1650-0250-0.100-0.0270-0.0200-0.10·Technical specificationBrandBreakage rateHardness(HRC)Impactvalue(J/cm2)Droptimes(Times)Micro structureHF-C45≤1%45-65≥12≥12000M+CHF-50Mn≤1%50-65≥12≥12000M+CHF-60Mn≤1%55-65≥15≥12000M+CHF-65Mn≤1%55-65≥15≥12000M+CHF-Q3≤1%55-65≥15≥12000M+CHF-40Cr≤1%55-65≥15≥12000M+CHF-42CrMo≤1%55-65≥15≥12000M+CHF-70Cr2≤1%58-65≥15≥15000M+CHF-B2≤1%58-65≥15≥15000M+CHF-B3≤1%58-65≥15≥15000M+CHF-B6≤1%58-65≥15≥15000M+CHF-B6A≤1%58-65≥15≥15000M+CHF-B7≤1%58-65≥15≥15000M+CHF-BU≤1%58-65≥15≥15000M+CHF-GCr15≤1%58-65≥15≥15000M+C ·Two Production process Rolling forging production line Hot rolling production line ·Hot rolling Grinding Ball Production(1)Steel rod inspecting: Main inspection(2)Steel rod feeding: Generally hanged to the material rack by crane, feeding the steel rod into rollgang by automatic upender.(3)Heating: Induction furnace, PLC full automatic control.(4)Skew rolling: Adopting two roller skew rolling,skew rolling the steel rod into steel ball.The main motor of skew rolling mill adopts frequency control.
