The Manufacturing Process Research on Medium Chrome Cast Iron Grinding Ball (2)

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 […]

The Manufacturing Process Research on Medium Chrome White Cast Iron Grinding Ball (1)

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

Experimental study on Cr12 high chromium grinding ball (2)

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 […]

Experimental study on Cr12 high chromium grinding balls (1)

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 […]

Application of new MQ-P-T technology in white cast iron balls (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 […]

Trial-manufacture and application of as-cast low chrome alloy casting balls (2)

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 […]
