6.Unique heat treatment process
Metallic materials consist of a microstructure of small crystals called "grains" or crystallites.
The nature of the grains (i.e. grain size and composition) is one of the most effective factors
that can determine the overall mechanical behavior of the metal. Heat treatment provides
an efficient way to manipulate the properties of the metal by controlling the rate of diffusion
and the rate of cooling within the microstructure. 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. Hardness gap between center and surface is less than 1.5 HRC.
7.Our study
High wear resistance performance and low consumption products:
a.Real elements, such as V, and Mo Ni, add in the casting process to increase the metal microstructures to improve the material wear resistance capability.
b.Feedback from our client mines for the trial testing. Our Cr, 10-12% grinding ball could achieve about 50% cost saving against with one international product's16% Cr in our client mine.
Long working life:
a.Our warmed machine oil technology could lead the hardness gap between center and surface is less than 1.5 HRC.
b.And also we utilize the control temper and control cooling technology.
c.All of these great improve the ball hardness anti –corrosion, impact value.
Customer design:
Flexible to design the grinding ball with reasonable hardness and impact value in a satiated the varies size grinding mills and different ores. Such as the force cooling grinding ball technology for the Cr 28 .
Microstructure Optimization:
We research and develop the different microstructure grinding balls as below :
a.M(Martensite) + S(sorbite)
b.M(Martensite) + T(troostite)
c.M + B (Bainite) or Baiite Grinding ball.
