Houde Grinding Forged Steel Ball - Φ20-î¦150mm | High Hardness Hrc 60-65, Zero Roundness Loss, Excellent Wear Resistance

Houde is specialized in manufacturing rolling forged grinding forged steel ball ranging diameter from I 20 to I 150mm.
Houde Grinding Balls have following advantages:precise dimensions,spherical geometry,high throughout hardness and outstanding mechanical performance.Meanwhile,the characteristics:excellent wear ability,permanent in shape and cracking-proof ensure our balls could be well and widely used in large-scale mines,power plant, cement plant and the other industry.Our balls have gained good reputation in both domestic and international mark due to the fact that using Houdea s grinding balls can reduce the usage of grinding balls,improve the fineness of slurry,and therefore improve productivity of communication and flotation process.Derailed properties are as follows:1.High throughout hardness:the surface hardness could be HRC 60-65;the average volumetric hardness could be HRC 60-65.2.AKa 12J/cmA .3.Good ductility and none breakage:our drop balls test result shows 100% better than national standard.4.No loss of roundness:in the mill, Houde balls wona t be out of round from start to finish.
High quality carbon round steel rods and hot rolled(or continuous casting)round steel rod from reputable steel mills are used as raw materials for Houde rolling forged grinding balls.Chemical Composition of steel rods used in our company is as follows: C:0.37-1.05Si:a 2.0% Cr:a 3.5%Mo,V,Ti,Cu:a 0.5%Ni:a 0.5% P:a 0.050% Mn:a 2.0%S:a 0.050%We could adjust the above chemical compositio
