In modern industry, the manufacture of steel balls requires very accurate dimensions and surface quality. These steel balls are mainly used in mines, power plants, cement plants, steel mills, silica sand plants, and coal chemical industries. One of the methods for making these steel balls is through skew rolling. Skew rolling is the forming process by the use of two specially designed continuously-rotary vertical rollers. The steel bar is fed to the rollers, and through the squeezing and cutting of the rollers, ultra-final round steel balls are formed. It can be said that the rolling process of each steel ball is independent. The skew-rolling process, similar to roll forging, this manufacturing process allows the steel ball to contain the dual qualities of steel ball forging and steel ball rolling.
Hot rolled steel balls: The quality of grinding media (balls, baseballs) plays a decisive role in the operating costs of the dressing plant.
At present, the product specifications of the skew rolled steel ball range from φ20 to φ150. The wear-resisting steel balls for gold mines, silver mines, copper mines and iron mines are widely used and promoted in actual mines, saving great purchase costs for customers, greatly increasing the grinding production, and achieving a remarkable economy benefit.
Steel ball skew rolling mill is a special equipment for producing grinding steel balls, bearing ball blanks and other metal ball parts (nominal diameter φ20-φ150mm) by adopting the spiral roller pass rolling forming process, and can also be used for producing other rotary parts or blanks. The steel ball rolling machine adopts a semi-closed frame, easy to change the rollers, the adjustment function of the rolling mill is complete, the rigidity of the stand is good, and the precision of the rolled product is high. The whole steel ball rolling machine consists of main motor, reducer, compound device, universal coupling , work host and other parts.
1) Hot rolled steel ball has all the advantages of steel, and been used as high quality grinding balls after heat treatment.
2) High efficiency, large capacity, mechanization of steel ball rolling production, high degree of automation, no need for manual production, and less and less interference of worker factors.
3) Stable quality, high hardness, good hardenability, compact microstructure, small crystal grain, homogeneous steel ball with no deformation, no breaking circle, good wear resistance, impact toughness is as high as 12-35 j/cm2, and the crushing rate is less than 1%.
4) Low energy consumption, no pollution, low labor intensity, low production cost, good formability, small geometric tolerance, and stable quality.
5) The wear rate is low and the service life is long. It is an existing cast iron ball, and the price is reasonable.
6) The steel ball hardness is up to 60 ~ 67 HRC, internal and external hardness is balanced.
7) Impact toughness up to 12~35j/cm3.
8) Large proportion (7.8~7.85 J / cm3).
9) The surface quality of the steel ball is good, and the hardness inside and outside is balanced (hardness difference <5HRC);
10) Low crushing rate, long service life, high ball density, strong impact toughness;
