Hot rolling steel ball is a new technology of skew rolling, it is the breakthrough of grinding steel balls industry’s process technology,and gradually replacing cast steel balls.
After many years of our company’s engineers on the full research and transformation of skew rolling mill production line,Develop and manufacture the third generation hot rolling skew rolling mill production line,And has a complete set of hot-rolled steel ball production technology.
The hot rolling skew rolling mill production line for grinding steel ball include:SCD30,SCD40,SCD50,SCD60,SCD80,SCD100,SCD120 models,It is also equipped with four types for each model: common type, common high-speed type, high-speed type and ultra high-speed type,It can produce φ20～φ125 steel balls and cylpeb,Meet the requirements of different users

After checking the round bar(material) to confirm it meets the production process requirements.
Before rolling, the round bar should be heated up to a suitable temperature in the continuous heating furnace.
After the hot steel bar goes into the skew rolling mill, it will rotate forward between the two rollers with a special spiral groove, and continuously rolled into balls finally. Each set of skew rolling mill can roll 40～1600 balls/min.
The rolled hot balls are under quenching-tempering process, The steel ball has high and even hardness and impact toughness.
Our company can be according to the product specifications and specific requirements of the owner to design the optimal production line and advanced, suitable production technology.
