Progress of forging steel ball production process May 14, 2018

Industrialization and the improvement of human life quality have led to the development of the entire mine industry. Steel balls have become necessary for crushing and grinding of mines, but at the same time it is one of the very common consumables in the industry. Practice has proved that under the conditions of the same miner, the forged steel grinding ball has a certain cost advantage over the cast steel ball. Thus, it can be seen that the forging steel grinding ball has continuously developed into an inevitable one.

 

Forged steel grinding ball has been developed so far, its production process has experienced three different stages of the traditional process, oblique rolling process and rotary cutting and forging process. The traditional forged steel ball is a forged steel ball, using an air hammer to forge the raw material to a certain amount of deformation, increase the compression ratio, so that the structure of the wear-resistant ball is more compact, and improves the toughness and hardness.

 

The traditional process requires that the material be sized according to the size, then heated to a certain temperature with coal or natural gas, and then air hammer forging, heat treatment, product inspection and other steps. There are too many drawbacks, so with the development of the times, traditional crafts have gradually faded out of the stage of history and replaced by slanting processes.

 

The obliquely forged steel grinding ball is actually heated by an electric furnace to feed the entire round steel bar. It is fed into the roller through the conveying device, and the roller is driven by the motor and reducer to rotate. The roller can use its own ball slot design to cut the high temperature round steel bar. Draw into the ball. The whole process does not require blanking, and no air hammer forging is required, which greatly increases the production efficiency. The labor intensity of workers is also greatly reduced, and the damage caused by noise is greatly reduced.

 

Although the slanting technology of forged steel ball is very light, there are also deficiencies. With the increasing diameter of the side ball mill and the appearance of the semi-autogenous mill, the demand for the ball of the ball mill has also been gradually updated from the small diameter to Large diameter, so in the heat treatment process of the forged steel ball using super-advanced tempering quenching process, through multiple quenching temperature control, continuous tempering and other processes, so that the ball in the volume hardness uniformity and overall wear Sex has a better performance.

 

In addition to the excellent performance in the performance of forged steel grinding balls, the rotary cutting and forging production line of forged steel grinding balls also has the advantages of fast heating, high efficiency, intelligence, environmental protection and energy saving. Not only that, forged steel grinding ball also adapted to the current requirements of environmental protection, pollution, and labor.http://www.grindingballsmedia.com/
