Cold Rolling – UPTIME

The use case deals with cold rolling mill for the production of steel strapping. Cold rolling is a process of reduction of the cross-sectional area or shaping a metal piece through the deformation caused by a pair of rotating in opposite directions metal rolls.

Prediction and analysis of cold rolling mill vibration based

Nov 01, 2020 · The mill vibration data was collected from the UCM cold rolling plant. It was believed that mill chatter during cold rolling is due to abnormal periodic oscillations of the rolls in the vertical direction,. Heidari et al. used an accelerometer located at the top of the stand to detect the vertical movement of the rolling mill.

Dynamic characteristics of cold rolling mill and strip

The dynamic model of cold rolling mill based on strip flatness and thickness integrated control was proposed, containing the following sub-models: the rolling process model, the dynamic model of rolls along axial direction, and the compensation model. Based on the rule of volume flow rate, the dynamic rolling process model was built.

New Rolling Method R f Reversing Cold Rolling Mill

Since not being c ontinuous rolling, the reversing cold rolling mill has had drawbacks such that unrolled portions necessarily produced in head and tail ends reduce yield, and time consuming works such as replacement of coils, threading of the strip and holding of the strip with the winding reel decrease productivity.

Hot Strip Mill and Cold Rolling Mill | TSUBAKIMOTO CHAIN GROUP

There are two types of rolling. With hot rolling, heated metal goes through a rolling machine where it is worked into a sheet or bar. With cold rolling, sheet steel is made thinner at normal temperatures, and its surface is made smooth and uniform. Tsubaki products are used in both hot and cold rolling.
