Introduction of the hi-tech cast grinding ball

1.Mechanical properties

2.Chemical composition

3.Heat treatment

     Heat treatment is the key step of the whole  production process.In the R&D practice,Dongfang invents 

 Application Method for Warm Period Timing Quenching in Grinding Materials Heat Treatment and other skills.

 Machine oil is used to quench,making workpiece heated evenly,promoting the first formed carbide decompose

 once again and then forming uniformly distributed reticular carbides in the matrix.

    Steel chemistry and heat treatment are tailored to ball diameter and intended application to optimize mechanical

intergrity and wear resistance. This produces a ball which resists spalling and breakage.

   Dongfang has a Provincial High-Tech Center with various test equipments,which has reached a leading level in 

this field.The independent R&D "Warm Period Timing Oil Quenching Heat Treatment"has been authorized as National

Invention Patent.Through this skill,Dongfang is able to manufacture a series of products,such as high anti-wear 

ordinary casting grinding ball and cylpeb and high-performance composite metal hammer.This series of products are 

identified as Anhui High-tech Products and 18 of them have been recognised as National Invention Patent and Utility 

Model Patent.
