Principles of Development of Grinding Media with Increased Wear Resistance. Part 2. Optimization of Steel Composition to Suit Conditions of Operation of Grinding Media

摘要

The compositions of wear-resistant steels used as the material for grinding media are validated in order to obtain the optimal relation between the wear resistance and cost. Mathematical experiment planning reveals that low-alloyed hypereutectiod steels with the austenite-martensite structure without secondary carbides and eutectoid steels with the tempered martensite structure are the most promising for impact-abrasive-corrosive wear conditions.
