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 […]
