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.
