An Efficient Steel Ball Forging Process In The Steel Ball Making Machine

Wear-resistant steel ball, also known as wear-resistant medium for grinding machine, is a consumable, its main purpose is to grind the material to make the material finer to meet the standard of use. The Wear-resistant steel ball is mainly used in mines, power plants, cement plants, steel plants, silica sand plants, coal chemical industries, etc. The annual consumption of steel balls in the world is between 30 million and 50 million tons, of which the consumption of Chinese steel balls is between 3 million and 5 million tons, is a major consumer of steel balls.

The steel ball making process can be divided into three types: forged steel balls, cast steel balls and hot rolled steel balls.

Forged steel ball

After the round steel is cut, it is forged with an air hammer. The wear resistance of the forged steel ball is closely related to the used material of the round steel and the quality of the impurities or round steel.

The main material of forged steel ball: mostly made of high manganese steel (50Mn and 60Mn or 65Mn). At present, the wear resistance of 75MnCr is comparable to that of high-chromium balls.

Chromium alloy is the main component of cast steel ball. Its strength and density are lower than that of forged steel ball. The breaking rate is much higher than other steel balls. According to the level of chromium content, the wear-resistant ball can be pided into the following types:

forging is better than casting to produce steel ball

casting operation is dangerous, the internal structure is poor, the efficiency is lower

Hot rolled steel ball

The hot-rolled steel ball is produced in the rotary cutting production line. It has risen rapidly in recent years. It not only has high production efficiency but also high degree of automation, high material utilization rate, stable steel ball size and quality, and excellent cost performance, but the quality is not as good as forged steel ball.

Anyang Forging Press recently developed a CNC steel ball forging-rolling line for a steel ball production customer in Anshan, effectively taking into account the advantages of good quality of forged steel balls and high production efficiency of rolled steel balls. Billet hot shearing shears the bar, using a forging manipulator to transfer the material to the CNC die forging hammer, pre-forge them into balls. The use of die forging ensures the forging ratio of the forgings to ensure the quality of the steel ball and greatly improves the forging efficiency. Then, the forged steel ball is rounded by a roller machine similar to the principle of the cross mill to ensure the roundness of the steel ball is perfect. Generally, the cross-rolling mill can only roll steel balls of less than 120 mm, however the steel ball size that can be produced theoretically by the forging-rolling steel ball process does not have an upper limit. This steel ball production process is bound to become a new trend leading the production of steel balls.
