PDF | The effect of carbide content on the wear resistance of high chromium cast irons was evaluated by means of ball mill testing. Martensitic cast irons containing from 13 to 41% carbide volume ...
Heat treatment of high chromium grinding ball is the main method to obtain good wear resistance. The research on high chromium cast iron ball mainly focuses on chemical composition selection, heat treatment process determination, modifier selection, good carbide type and wear mechanism.
Which is best for economics of grinding media do you think: High chrome steel balls and forged steel balls.I would like to know if anyone has an idea or paper on the benefits of high chromium steel balls over the forged steel balls.
Due to the high chromium content in high chromium steel ball, it is easy to be in the surface of the iron liquid, so it seems that the liquid flow is poor, but it is in fact a good flow. 4 because of the high chromium casting riser is not easy to be removed, thus modeling in the form of riser should use side riser or knock off. 5.
Chromium alloy is the main composition of casting steel ball with diameter of 6 mm to 140 mm. According to different chromium content, the grinding ball can be divided into three kinds, namely low, medium and high chromium balls. The hardness of relevant balls are HRC≥45, HRC≥50 and HRC≥58 respectively, with diameter of 6 mm to 140 mm.
Alibaba offers 1,166 high chromium forged grinding ball products. About 69% of these are casting, 17% are other fabrication services, and 2% are cast & forged. A wide variety of high chromium forged grinding ball options are available to you, such as free samples.
The finish grinding process for cement materials uses ball mills with differently sized grinding balls. Because the grinding takes place through the impact and friction of the balls, balls with a high wear resistance are desirable and the materials of choice are the high-chromium white cast irons.
