Professional Manufacture High Hardness Hot Rolling Steel Ball for Sale
Hot-rolled steel ball is a kind of ball milling ball using a new rolling process technology.
Through rolling technology. Hot-rolled steel balls are formed by heating round steel bars in a continuous heating furnace and then sending them to a steel ball rolling mill for rolling. After rolling, the red-hot steel balls immediately enter the heat treatment equipment for quenching and tempering to ensure that they have a high and uniform hardness. Finally, the qualified products will be sent to the finished product warehouse for packaging and shipped to customers.

High quality: Hot-rolled steel ball has high overall hardness, surface hardness can reach 55-65HRC, volume hardness reaches 50-62HRC, and hardness gradient distribution is uniform. Its impact toughness is greater than 12J/cm², the crushing rate is low, and the anti-peeling and anti-crushing performance is more than 10 times that of general cast and forged steel balls.
High production efficiency: The production is mechanized and automated, with less manpower and less interference from human factors, which is suitable for large-scale production.
Stable quality: The metallographic structure is dense, the grains are fine, the steel ball does not deform or lose roundness, has good wear resistance and long service life.
Environmental protection and energy saving: low energy consumption, no pollution, low labor intensity and low production cost.
