Heat treatment of high chromium grinding ball is the main method to obtain good wear resistance. The research on high chromium cast iron ball mainly focuses on chemical composition selection, heat treatment process determination, modifier selection, good carbide type and wear mechanism.
grinding roll from NF6357Ahigh chrome Iron alloy for crushing of solid mineral and grinding operations in a ball mill for cement production. The casting conditions, and the evolved microstructure after heat treatment greatly affect the wear performance of high chromium white cast iron.
Nov 21, 2008· This work aimed to model the temperature distribution, phase transformation and residual stress induced during the heat treatment of grinding balls of 3 and 5 in. diameter. The temperature model considered factors such as the heating of the water and the formation of a steam layer that surrounds the balls at the start of the quenching.
The heat treatment of Forged Grinding Ball is the process of heat, keep warm, then cool down, cooled at different speeds. It can not be interrupted in this process. Heat treatment process is also one of the important factors to ensure the quality of Grinding Balls.
Grinding steel ball heat treatment refers to the technique of heating billets to a certain temperature, maintaining some time and cooling at different speeds. Grinding steel ball heat treatment typically includes heating, insulation and cooling processes. These steps .

greatly affected by heat treatment. Improvement of grinding media has been a slow process. Grinding balls can beevaluated by the user by keeping records of ball consumption and ore tonnage. But this procedure requires long testing times of months or years (Norman, 1948; ElKoussy, et al., 198 1; Moroz and Lorenzetti, 198 1; Howat,
Heat treatment furnace for grinding balls: Heat treatment process is the last process for producing cast grinding media mill different chrome content in grinding balls,the heat treatment technology is different. Middle casting grinding media balls and low chrome casting grinding media balls .
An austenitizing heat treatment usually comprised heating at temperatures between 750 and 790°C (1380 and 1450°F) with a soak time of 8 h. Air or furnace cooling, not over 30°C/h, was conducted followed by a tempering/stressrelief heat treatment. Refrigeration heat treatment is the more commonly practiced remedy for low hardness today.
