Molten steel refined in the converter is solidified in this process to produce billets of a given shape. The molten steel discharged from the converter is continuously poured with a ladle into a mold below for cooling. After the steel is cooled and solidified, it is cut to a given length before it is conveyed to the rolling process for shaping.
A major steel producer was not satisfied with the performance of the four-row tapered roller bearings that were installed in its cold rolling mill: steel shavings from the production process were getting into the bearings and having a detrimental effect on reliability.

Dec 03, 2015· The main sub-processes are (i) heating of steel slabs in the reheating furnace, (ii) descaling of the heated slab and its sizing in sizing press, (iii) rolling in the roughing mill and secondary descaling, (iv) rolling in the finishing mill, (v) control cooling of the hot rolled strip and (vi) coiling of the rolled strip.
5. Cluster Rolling Mills: In this type of rolling mill, there are two basic roles that are backed up by two or more rolls which are bigger than those two basic rolls. These backed up rolls give more pressure to the basic rolls to heavily press the strip.
The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
Cold rolling is accomplished by processing steel strip through a series of tandem rolling mill stands. Each stand has vertically stacked rolls that are powered by huge motors to impart high compressive stresses into the strip. Hot-rolled, pickled coils are fed into the cold rolling mill from an entry-
Steel Hot Rolling Mill Application Overview Temperature Control in the Hot Rolling Mill The Hot Rolling Mill is used to reheat shapes of steel to soften them enough so that they can be rolled thinner and longer through a series of rolling stands. The finished product can be either a strip, plate, rod, bar, wire, or shape (rails and H-beams).
Oct 31, 2013· Cold rolling in a tandem rolling mill. The rolling mill consists of 5-7 stands having four-high configuration (two large back-up rolls and two small work rolls). Annealing at a temperature 1100-1300ºF (600-700ºC) in a controlled reducing atmosphere (commonly a mixture of Hydrogen and Nitrogen ) preventing oxidation of the steel surface.
The WHEMCO companies in Pennsylvania and Ohio, USA manufacture a full range of mill rolls – spun cast iron, cast steel and forged steel. Each of our roll manufacturing facilities has the expertise, equipment and experience to meet the most demanding rolling mill applications. WHEMCO is North America's largest and most diverse roll manufacturer.
In roughing mills, equipment is used to reduce the thickness of the steel while at the same time extending the overall length, to form the metal to roughly the final thickness. The Hot Finish mill forms the strip to the final dimension.

Hot rolling. This process stretches a slab into a strip. The slab is reheated to approximately 1250°C and rolled in hot conditions. The resultant strip steel is wound into a roll like toilet paper (hot coil). Chains for lifting; Toughrollers; Conveyor chains for conveying semi-finished products
Development and application of roll contour configuration in temper rolling mill for hot rolled thin gauge steel strip Article in Ironmaking & Steelmaking 39(3):163-170 · April 2012 with 35 Reads
Application of Hot Rolling Lubrication on a Reversing Coil/Plate Mill Roll lubrication was introduced to the 4-high Steckel mill at Nucor Steel Tuscaloosa Inc. in 2011. It was found that the benefits included a significant extension to roll service life and notable reduction of mill torque. This paper will describe the mechanism of lubrication in
al. 1990 s) for application to steel temper rolling of annealed steel product down to 0.4 mm in thickness. However, the shortcomings of this approach were immediately apparent when attempts were made to analyse tinplate temper rolling, foil rolling and double reduction rolling data. A major development in the cold rolling of thin strip
