Characteristics and uses of forged steel balls in iron ore mines

After the round bar material has passed the inspection, it is cut according to the size of the forged steel ball in the iron mine; the steel forging is heated to a certain temperature by the intermediate frequency furnace to ensure the effective occurrence variable in the forging; the red hot steel forging is sent In the air hammer, it is processed by skilled operators. The red hot steel ball after forging immediately enters the specially designed heat treatment equipment for quenching-tempering heat treatment, so that the forged steel ball produced by the iron mine obtains a high and uniform hardness value.

The iron ore forged steel ball has a smooth surface and uniform hardness to ensure that it does not lose its roundness during the grinding process. It is produced by forging hot-rolling forging and forming, with no defects on the surface, no deformation, no loss of roundness, and wear resistance. It is relatively high. Because of the specificity of the raw materials, it is impossible to cut corners, so the stability of the steel ball is relatively high.

Due to the direct forging of round steel, the internal density is high and the fine grain size is high, which enhances the drop resistance and impact toughness of the iron ore forged steel ball, thereby reducing the ball breaking rate; the ball consumption can be reduced. Under normal circumstances, iron ore forged steel balls have the advantage of high hardness: the surface hardness reaches 55~65HRC, and the volume hardness reaches 50~63HRC;

The impact toughness is generally higher than 15 J/cm2, and the falling ball impact fatigue life is greater than 2,200.www.grindingballsmedia.com
