Description of the grinding
media balls with high chromium
1.Physical properties
| HRC | Impact value | Metallurgical structure | Falling times | Breakage rate |
| ≥*0 | ≥3.5 | M+C | ****0 | ≤0.5% |
2.Chemical composition
| C | Si | Mn | Cr | P | S |
| 2.**3.2 | ≤1.0 | ≤1.0 | ****8 | ≤0.*0 |
≤0.*6 |
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.
Quality factor is significant to Dongfang.
For years,according to quality and environment management system,specified
programs and quality brochures,Dongfang cultivates a quality
&
inspection team to manage the whole production process.And
we passed ISO***1:***8 Quality Management System, ISO****1:***4
Evironment Management System and GB/T****1:***1 Occupational
Health and Safety Management System.
