roduct Description
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.
Other Information
3 > Production craft contrast
Ordinary company : degree of automation is less than manual intervention, there is no guarantee
that the stability of each batch steel ball.
houde : Fully automated production lines, greatly reduced the manual intervention, to ensure the
stability of different batch grinding steel ball quality.
