Description

 

一、Product Brief

High chromium alloy cast balls and casting segments are wear - resistant cast balls for ball mills with large market usage, especially oil quenched high chromium balls, which have high hardness and wear resistance. As the most wear - resistant alloy element, chromium accounts for more than 10% of the high chromium ball composition, and even 26% of the ultra - high chromium ball chromium element, belonging to the bull devil in the wear - resistant ball. China's casting technology of high chromium ball has witnessed rapid development since the reform and opening up. It has developed from traditional manual casting to automatic constant temperature casting nowadays. With the improvement of technology, the product quality has also made a qualitative leap. Flow chart:

 

The high chromium ball milling section were manufactured by the new automation process which has the advantages of good quality stability, small batch quality difference, good appearance of steel balls, low breakage rate, uniform hardness and non - breakage resistance. It is widely used in metal ore ball mills such as gold mine, copper mine, iron mine, high chromium ball used in cement plant, high chromium alloy ball used in power plant, etc.
