Experimental study on Cr12 high chromium grinding ball (2)
/in Grinding Media Balls /by Hexin Africa2.1 Effect of modification on the microstructure of Cr12 high chromium cast balls By comparing the enlarged photograph of high chromium cast ball CR12, without modification and after modification, it can be seen that without modification, the high chromium cast ball Gold Carmen structure, in which the carbonization, the materials are all, have, intermittent, reticulation […]
Experimental study on Cr12 high chromium grinding balls (1)
/in Grinding Media Balls /by Hexin AfricaWith the development of wear resistance, materials, and related technologies, cr-series white cast iron has been used more and more widely in the grinding industry, especially in high-chromium cast iron, which is a kind of wear-resistant material, it has been fully utilized in the major industrialized countries of the world. We can find that its […]
Application of new MQ-P-T technology in white cast iron balls (3）
/in Grinding Media Balls /by Hexin AfricaOn the one hand, the addition of chromium in casting grinding ball decreases the carbon content of the eutectic point and decreases the austenite area in the phase diagram. On the other hand, the type of carbide structure changes from reticulate M3C type to isolated M7C3 type, and the hardness of carbide increases, from 850 […]
Application of new MQ-P-T technology in white cast iron balls (2）
/in Grinding Media Balls /by Hexin AfricaThe high chromium cast iron products treated in this paper are made of hot metal with a temperature of 1550 °C, which are cast into 80mm diameter high chromium cast iron grinding balls in a cold mould. The chemical composition of the material is shown in Table 1.
Application of new MQ-P-T technology in white cast iron balls (1)
/in Grinding Media Balls /by Hexin AfricaAbstract: Fe-2.4C-12Cr high chrome white cast iron balls with a diameter of 80mm was quenched and tempered with water and air by MQ-P-T method, analysis of mechanical properties and microstructure, weaving, alignment, comparison. The strengthening and toughening mechanism of MQ-P-T treated high chromium cast iron was investigated using micro-and microstructure characterization. The results show that […]
