Working principle of cold rolling mill

Cold rolling mill is a kind of cold rolling equipment for steel bars. Not only can the hot-rolled wire rod with a diameter of 6.5 mm to 12 mm be processed into cold-rolled ribbed steel bars with a standard taper diameter of 5 mm to 12 mm, but also the automatic program is high, the production efficiency is fast and the energy consumption is low, which is a good helper to reduce the production of finished products and improve the production efficiency. So it is very popular now, but when it comes to the working principle of this device, many people really have a little knowledge. Let's have a look.

Fully automatic cold rolling mill

Generally, the cold rolling mill uses a motor to drag the steel bar, that is, the bearing roller and the working roller of the cold rolling mill jointly exert force on the two surfaces of the steel bar. The purpose of rolling cold-rolled ribbed steel bars with different diameters is achieved by changing the gap between continuous rolls, as follows:

1 load bearing roller:

The bearing roller of automatic cold rolling mill is the roller closest to the centrifuge seat. When producing ribbed steel bars, the rollers play the role of supporting the steel bars, and the gravity of the steel bars and the gravity of the working rollers are evenly distributed on the central rollers, thus resulting in ribs on the lower surface of the steel bars.

2 Work roll:

The working roll of automatic cold rolling mill is above the bearing roll and farthest from the frame. Therefore, when the roller regenerates the ribbed steel bar, it mainly plays the role of the steel bar lifted by the rolling bearing roller, thus causing the ribs on the upper surface of the steel bar.

The above is an introduction to the working principle of cold rolling mill, hoping to help you understand it further. At the same time, for the safe use of equipment and the qualification of products, everyone should not use it beyond the scope when using it, and roll it according to the rolling standard to avoid damaging some mechanical parts of the cold rolling mill.
