What is the high chromium steel ball  

High chromium steel ball is the most important grinding body in the ball mill, high chromium steel ball is produced by medium frequency furnace smelting, metal mold or sand casting, so the domestic wear-resistant material manufacturers are often called high chromium alloy casting ball, known as grinding steel ball abroad.  

Two, the use of high chromium steel ball  

High chromium steel ball is widely used in metallurgical mining, cement building materials, thermal power generation, flue gas desulfurization, aerated concrete, magnetic materials, chemical industry, coal water slurry, pellet ore, slag, ultrafine powder, fly ash, calcium carbonate, quartz sand and other industries.  

Three, the advantages of high chromium steel ball  

1. Wear resistance of high chromium ball is more than 2 times of ordinary low chromium ball and forging steel ball.  

2. Prolong the cycle of adding balls, greatly reduce the labor intensity of workers, especially greatly reduce the number of adding balls.  

3. The steel ball grading stability is not easy to change, increase the fineness of ore powder, improve the output of the table, ensure the quality of ore powder.
