Forging steel ball production Process

1. The materials of the grinding steel balls is ifferent grade round steel bars with various chemical composition.

2. The round bars are heated to a proper temperature in a continuous furnace before rolling.

3. Red hot bar is conveyed into the skew rolling mill, then it rotates forward between two rolls with special spiral 7L. As this processcontinues, it is gradually rolled into steel balls. A single skew olling mill can produce 60 200 steel balls per minute.

4.The red hot steel balls are transported directly to the online heat treatment equipment, which is specially designed for quenching andtempering. This makes sure steel balls can obtain high and uniform hardness.

5.Finished steel balls are characterized with precise size uniform hardness, good wear resistance and mechanical properties.

6.The products passed inspection are transported to the packaging workshop and then delivered to customers after packed.

High chromium alloy steel ball production Process

High chromium alloy steel ball of ball mill is widely used in powder manufacture and ultra-fine processing for cement building materials, metal mining, coal slurry thermal power, chemical engineering, ceramic coating, light industry paper, magnetic materials and other industries. The surface hardness can reach 65HRC, with average hardness gradient distribution, low abrasion, good toughness, and the quality of finished product is as good as GB/t17445-2009 standard. There will be No deformed problems occurring since the first time to use. It can improve the cement Blaine Test and ore concentrates recovery rate, improve the production capacity of grinding machine, prolong the working life of the mill liner, and reduce the production cost.
