Casting grinding balls φ20-150

一、Product Brief

The cast steel balls for ball mill are generally divided into low chromium cast steel balls, medium chromium cast steel balls, high chromium cast steel balls, ultra - high chromium cast steel balls and multi - alloy steel balls according to the content of alloying elements added. Generally, the chromium content in 1 - 3% is called low chromium alloy ball, the chromium content in 5 - 8% is called medium chromium alloy ball, the chromium content in more than 10% is called high chromium alloy ball, and the chromium content in more than 17 - 26% is called ultra - high chromium ball. Under the same working conditions, the higher the chromium content, the better the wear resistance of steel balls. Because of the high price of chromium, the performance - price ratio is generally pursued, and the matched steel balls with chromium content are selected according to the ore properties of each mine.
