Cold rolling mill - ArcelorMittal in Belgium

In our cold rolling mills (Ghent & Liège) we convert steel strips into a finished product with a thickness of no less than 0.15mm and no more than 3mm. How does this work? First we need to remove the scale layer which was formed during hot rolling. This is done by sending the coil through a heated acid solution, a process referred to as "pickling".

Cold Working: Definition, Methods, Working Process ...

This cold rolling process is carried below the recrystallization temperature of the metal or, in most cases at room temperature, it is called cold rolling. Usually, cold rolling is used after the hot rolling of metal to give the metal a clean and smooth finishing. It also increases tensile strength and stiffness.

Technical Review UDC 621 . 771 : 621 . 783 - Nippon Steel

significant change was taking place in the field of cold strip rolling. That year, a new process directly linking a tandem cold mill with a pickling line, called a continuous descaling cold rolling mill (CDCM) 2), began commercial operations at the Kimitsu Works. The development of helical turners that enabled direct linking of the two lines ...

SMS group : Cold pilger mills

Cold pilgering is a rolling process for metal tubes that reduces diameters and wall thicknesses. The Process. Located inside the tube is a stationary mandrel (1) which tapers in the rolling direction. This is attached to a long mandrel bar (2) which is secured in, and rotated by, a thrust block. Two dies (3) "form" the tubular stock in the same way that a rolling pin rolls out pastry.

What Is A Rolling Mill? | Metal Processing Machinery ...

In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes. Roll stands, holding pairs of rolls, are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams, angle stock, channel stock, and …

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 …

Rolling Process: Definition, Working Principle ...

Rolling Process Definition. The rolling process is a metalworking operation in which metal strips pass through a set of rollers to reduce sheet thickness and achieve uniform thickness throughout the sheet. The sheet is deformed along the linear axis. Typically after the rolling, metal sheets go through annealing which is done under a closed environment of nitrogen.
