Advantages and density of hot rolled steel balls
The hot-rolled steel ball has all the advantages of steel when it is used. It becomes a high-quality ball-milling ball after heat treatment in use. The hot-rolled steel ball has high production efficiency, large output, mechanized rolling ball production, and high degree of automation. The production process of the operation, the use of people is small, the interference of human factors is small.
The quality of the hot-rolled steel ball is stable, the hardness is high, the hardenability is good, the metallographic structure is dense, the grain is fine, and it is not deformed. The steel ball will not be deformed from beginning to end, and the roundness is good, the wear resistance is good, and the impact toughness is high. 12-35J/cm2, the breaking rate is less than 1%, low energy consumption, no pollution, low labor intensity and low production cost.
The hot-rolled steel ball has good forming, small geometric tolerance, stable quality, low wear rate and long service life. It is 2~5 times of the existing cast iron ball and forged steel ball, and the price is equivalent. The hardness of the steel ball can reach 60~67HRC, the hardness is balanced inside and outside, and the hardness difference is <5HRC.
