GENERAL ASPECTS OF ROLL COOLING FOR HOT &

The so-called selective roll cooling is applied mainly for cold rolling mills to control the asymmetrical flatness deviations the strip width. There are furthermore across applications for special cast-rolling mills for narrow-gauge hot strip production. Normally, two rows of nozzles are used in one header. The row of nozzles directed to Metal Plate Rolls (Types and Applications) MachineMfgAsymmetrical 3 rolls plate bending machine is applied to roll low carbon steel which length below 2500mm and thickness below 4mm into cylinder or arc segment. In the process of working, the plate rolling process is fast, saving energy and reducing the production cost. However, the pre-curving linear segment is twice the thickness of the plate. Precision Steel Roll-forming Technology Howick LtdSteal the advantage in construction with Howick steel roll forming machines and technology. Howick is a pioneer in the technology of precision light steel roll-forming machines. For over 40 years, our commitment to innovation in Cold Formed Steel (also known as Light Gauge Steel), precision manufacturing, uncompromising quality and exemplary

Steel Plate Rolling Services Heavy Plate Rolling

The narrower the width of the plate entering the machine, the thicker the plate that can be rolled. For example, CMRP can roll a 2" thick, 12' wide steel plate, or we can roll a 12" thick, 3' wide steel plate. We can also roll thick material to very tight diametersfor example, 2" thick, 10" wide material can be rolled to a 19" diameter. The Art of Metal Roll Bending Acrotech, Inc.Commercial quality hot rolled and cold rolled steels in the 1020 carbon range have a wider tolerance of spring-back and are, therefore, subject to more variation than the lower carbon steels The Hot Rolling Process - California Steel Industries, Inc.The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

They have a great influence on the structure and performance of steel. The rolling of steel is mainly hot rolling, and cold rolling is usually used only for the production of steel with precise sizes such as small-sized section steel and thin plates.
