Grinding Media Balls, mill balls for ball mill, including casting balls and forged steel balls, tell you the difference and how to select.
1) The mechanical properties and anti-fatigue, and impact properties of the white cast grinding balls are up to the expected values. The hardness distribution is shown in Fig. 1. The ball’s microstructure after as-cast and sub-temperature treatment is as shown in fig. 2 and Fig. 3.
2.1 Main Scheme (1) Determining the content of thixotropic element Mn according to the cast iron mill ball diameter and cooling method, adopting the correct composition design to realize the expected goal of as-cast structure, strengthening the compound modification effect of rare earth to realize the carbide necking, broken net, and bar transformation, adopting the […]
Abstract: By comparing to the traditional technology, white cast iron grinding ball manufactured by the new technology is characterized by better tenacity, stronger hardness, and smaller stress. The working life of the ball and its adaptability to various conditions were greatly improved. Keywords: scope production; medium chrome white cast iron; grinding ball
2.1 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 […]
With 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 […]
On 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 […]
The 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.
Abstract: 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 […]
According to the designed composition, the molten iron is smelted by induction furnace; after slag removal, temperature adjustment, alloy addition, sampling analysis, and adjusting the composition to be qualified, the molten iron is drawn out at 1500 ~ 1550 °C and is modified by the inner-ladle method, at 1400 ~ 1450 °C, Molten iron is […]
According to the requirements of mechanical properties, after repeated tests, the following chemical composition and scope have been designed: Carbon is the basic element that affects its structure and properties and the important factor that affects the properties of alloy grinding balls. With the increase of carbon content, the EUTECTIC carbides increased and distributed in […]
