Rolling, in technology, the principal method of forming molten metals, glass, or other substances into shapes that are small in cross-section in comparison with their length, such as bars, sheets, rods, rails, girders, and wires. Rolling is the most widely used method of shaping metals and is
In the metalworking industry, as we know, rolling is a metal forming process, which the metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform.Rolling is divided into two types that are hot rolling and cold rolling according to the different of the temperature when metal rolled.

The number of stands ranges from 2 to 18. Tandem mills can be either of hot or cold rolling mill types. Defects. In hot rolling, if the temperature of the workpiece is not uniform the flow of the material will occur more in the warmer parts and less in the cooler. If the temperature difference is great enough cracking and tearing can occur.

thin slabs to the hot-rolling temperature of approx. 1,100° C. The thin strips are transported with a very even tem-perature out of the equalizing furnace, through the high-pressure descaler and into the Steckel mill. Depending on the annual production level you want, the Steckel mill is built with one stand or two as a twin stand version.
the roll benders. Initially, the HC mill was applied to the cold rolling mills, and then to the finishing mill stands of the continuous hot rolling mill of the Yawata Works, which was commissioned in 1982. The PC mill was first used commercially for the continuous hot rolling mill of Hirohata, which was commissioned in 1984, and then for the
