Cold Rolling an overview ScienceDirect Topics

Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34].This effect has been shown in Fig. 5.14.Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the time of holding [35].

Prediction and analysis of cold rolling mill vibration

1/11/2020· A mill vibration monitoring system was developed to monitor the oscillating movements of the rolls in the tandem cold rolling mill. A sketch of the rolling mill vibration data monitoring system and the specific locations of the sensors (locations A, B, C, and D) were shown in Fig. 3.Location A was the operation side of the bottom work roll (WR) bearing, location B was the operation side of the

Dynamic analysis of vibration stability in tandem cold

1/10/2019· Recently, mill chatter has been recognized as the bottleneck in high speed rolling. Therefore, it is important to investigate the vibration mechanism and vibrational stability in a tandem cold rolling mill. Many previous experiments were performed using a mass-spring structure system to study chatter characteristics in cold rolling.

Analysis of Startup Process and Its Optimization for a Two

Two-stand reversible cold rolling mills, a typical layout of which is shown in Figure 1, are also called compact cold mill (CCM). It was specially developed for moderate scale cold rolling plant. Strip breakage occurs frequently during the initial commission phase of some CCM, which has not been solved effectively. This phenomenon is the most severe when starting rolling or the strip running

Cold Rolling Process on Metals Industries Metallurgy

It is important to remember that the thickness of metal rolled by cold rolling is often considerable in excess of the initial roll setting, because the various mill parts get deformed elastically under the load encountered on the mill during cold rolling. When cold rolling strip, the thickness must be controlled to within close limits.

Abstract: This paper focuses on a new type of 8-roll cold rolling mill with the back-up bearing roll. Compared to the traditional 6-roll cold rolling mill, a thick-walled bearing roll is used to multi-support the intermediate roll. By the rack, the fan-shaped gears, the eccentric core shaft and the servo-cylinder, the work roll can be pushed down by this screw down device on the top of the

Rolling (metalworking) Wikipedia

The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by fabricators. Billets, for re-rolling, are subsequently rolled in either a merchant, bar or rod mill. Merchant or bar mills produce a variety of shaped products such as angles, channels, beams, rounds (long or coiled) and hexagons.
