Core features of Forever skew rolling steel ball production line

The skew rolling process is an advanced and efficient forming method for producing steel balls (grinding balls), especially suitable for large-scale production.

Core features of Forever skew rolling steel ball production line

Efficient continuous production:

Using hot rolling technology, round steel bars are continuously rolled into balls between two rolls rotating in the same direction. The single machine production capacity is extremely high, capable of producing tens to hundreds of steel balls per minute, making it very suitable for large-scale industrial production.

High material utilization rate:

Near net forming technology, steel balls are directly rolled out from the bar material without cutting waste, and the material utilization rate can reach over 95%, far higher than forging or casting processes, greatly saving raw material costs.

Streamlined fibrous tissue:

During the rolling process, the metal streamline is continuously distributed along the contour of the sphere and is not cut off. This makes the internal structure of the steel ball dense, and its mechanical properties (especially impact toughness and fatigue strength) superior to cast balls, comparable to or even better than forged balls.

Good dimensional accuracy and surface quality:

The geometric dimensions of the rolled steel balls are consistent, with high roundness and a smooth surface (with spiral patterns but no burrs), providing a uniform foundation for subsequent heat treatment.

Overview of skew rolling steel ball production line

The inclined rolling mill is used to produce steel balls or steel forgings. The angle between the two rolls of a skew rolling mill is generally 2-6; The rolling mill has a spiral hole pattern. When the two rolls rotate in the same direction, the round bar blank rotates in the opposite direction between the rolls and advances, and the round bar is rolled into the required shape through the spiral hole pattern.
