1 > High Hardness: Surface hardness: HRC57-67 HRC, volume hardness HRC56-64. 2 > High Impact Toughness: The impact toughness of our grinding balls is more than 12 J / cm2. 3 > Low Broken Rate: the actual broken rate is not higher than 1%. 4 > Good wear-resistant and lower wear rate. Product Feature 1)High quality High quality comes from every working procedure for the control . Grinding ball have no great differences in appearance, but in the actual effect of grinding efficiency is different, this is because the raw material, heat treatment process, equipment automation level and other factors can lead to the steel ball steel ball lapping efficiency differences, and ultimately affect the user cost of grinding . Every working procedure we always follow the details of the accused, by providing more wear- resisting of grinding ball to help customers to reduce the cost of grinding. Product Specification / Models 1 > Raw material contrast Ordinary company : directly using the scrap or various steel grades production, traditional little involvement in the high rate of grinding materials research and development. houde : have a deep cooperation with The Chinese academy of sciences and steel plant , according to different industry standard have in-depth research and development, developed raw material with higher grinding performance. Application 2 > Heat treatment of contrast Ordinary company : Usually use pure water cooling quenching with insulation barrels of tempering , the heat treatment method is easy to cause uneven hardness, the lack of resilience, steel ball high broken rate in practical use. houde : Closed cooling tower for effective control of quenching temperature within the scope of the standard, the composite heat treatment technology can improve the internal organization of steel ball, the ball while guarantee the hardness have sufficient toughness are less likely to break.
