Steel ball production line process

Forging steel ball process

The whole bar is heated in the medium frequency induction furnacehot cutting of bar shearing machine - pre-forging of air hammer - final forging of air hammer - subsequent heat treatment. the forging process of The air hammer is suitable for all kinds diameter of steel balls, especially large diameter and very large diameter steel balls. in one equipment, the steel balls with large diameter span can be produced and the process is flexible and suitable for various batch production.

In the process, in order to improve efficiency, we design a air hammer for pre -forging, and another air hammer for final forging. But in fact, a pneumatic hammer can also complete to forge.

Rolling steel ball process

The rolling ball is the process of continuous deformation of the heated bar on the skew rolling mill to obtain the steel ball, the process is as follows:

The whole bar heating of medium frequency induction furnace - continuous rolling of skew rolling mill - subsequent heat treatment

The automation degree of rolling ball is very high, the production efficiency is much higher than the forging line, can produce the diameter of 125mm below the ball, rolling ball production line is also used for mass production, have a high requirements for the power of the production workshop

Forging and rolling steel ball process

Heating of whole bar in the medium frequency induction furnacehot shear of hydraulic shear - pre - forged steel ball of press ( high direction forming ellipse length ) - roll mill rounding forming - follow - up heat treatment

The rolling process can also be used to produce steel balls of various diameters, but for the reason of investment and efficiency, it is usually used to produce 100 - 200 mm diameter steel balls, which has achieved a better return on investment.

General heat treatment process about steel ball

The purpose of heat treatment of steel ball is to obtain the steel ball with high hardness and certain impact toughness, and adopt quenching process. The steel balls produced by various processes in order to improve the hardness and harden ability. The material uses high carbon and high chromium steel, before the forging and rolling, the heating temperature of 950 - 1050 ℃, after forging ,isothermal to 800 ℃, quenching, and then low temperature tempering.

Isothermal and quenching adopt continuous process, isothermal machine and quenching machine are connected in series with the production line, and the reasonable matching efficiency is obtained. the low temperature tempering has two forms, namely, online low temperature tempering and off-line low temperature tempering, which are related to the production, equipment floor area and other factors.
