HOT ROLLING PRACTICE – An Attempted Recollection Saral Dutta. B. Tech. (Hons.), I.I.T. Executive Director, ISP & RMD, SAIL (Retired) Rolling is a metal forming process in which metal stock is passed through a pair of rolls. There are two types of rolling process - flat and profile rolling. In flat rolling the final shape of the product is either
most modern pipe rolling mills. Gradually the mill shapes them from flat strips to the required circular pipe profile while the edges are prepared for high frequency welding. The bead is then cleaned for residual bead height with a carbide scraping tool online. A flying shear then cuts the pipe to the exact length required.

John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).

During the cold roll forming, operations such as punching, stamping, can be done online. Then, the metal section is cut at the end of the line to the desired length. The profiling operations are performed cold, because carried out at room temperature, they do not require the heating or melting of the metal for the manufacture of a profile.

2. The strength increase from cold work of forming has been incorporated for fl exural strength per Section A7.2 of AISI S100-16. 3. The eff ective moment of inertia for defl ection is calculated at a stress which results in a section modulus such that the stress times the section modulus at that stress is equal to the allowable moment.

In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill. Rolling mills often vary in the type, number, and position of rolls.
Cold rolling is a process that occurs after hot rolling in order to reduce the thickness, increase the yield and tensile strength and pliability of metal. It is a relatively expensive and labour-intensive process, but the improved mechanical properties increase the value of the finished product, whether that is a sheet, strip, or coil.
Hot rolling mill is a process of changing the thickness of hot material, in cold roll forming machine we just forming room temperature material. Cold roll-forming is a process of forming metal from the sheet, strip or coiled stock into shapes of essentially uniform cross-section by feeding the strips through successive pairs of rolls arranged ...
