Rolling Production

Sheets less than 1.5–3 mm thick are best cold-worked, and thus the sheets are usually further reduced in thickness in cold-rolling mills. After the reels are obtained from the continuous hot-rolling mill, they are transported to the cold-rolling unit, where scale is removed from the surface of the metal in a

Rolling (metalworking)

Early (hot rolling) strip mills did not produce strip suitable for tinplate, but in 1929 cold rolling began to be used to reduce the gauge further. The first strip mill in Great Britain was opened at Ebbw Vale in 1938 with an annual output of 200,000 tons. The strip mill

Hot Rolled vs Cold Rolled Steel

2020/7/9This is because the cold rolled steel actually work-hardens in the rolling process. For blacksmiths, this isn't much of a problem, since we are usually going to heat it up and reform it anyway. There is also an in-between finishing hot rolling process

Steckel mill

The Steckel mill allows the rolling of a large slab by providing heated reels on both sides of the mill to store the increased length produced during rolling. These drums allow for additional heat retention and thermal consistency in the rolled piece, which in turn produces

Roll Coating

Three-roll coating uses a metering roller, an applicator roller and a backup roller. Common three-roll configurations are nip feed coating and L-head coating. In three-roll nip feed coating (Fig. 10.8(a)), the nip formed by a metering roller and an applicator roller is flooded with coating liquid and functions as a reservoir (Greer, 1995; Grant, 1978).
