Basics of Rolling of Steel - IspatGuru
Hot rolling results in residual stress-free product. However, scaling is a major issue during hot rolling, due to which dimensional accuracy is difficult to maintain. Cold rolling of hot rolled steel is important, due to high accuracy and lack of oxide scaling. It is carried out below the recrystallization temperature and introduces work hardening.

Rolling at low speed is advantageous because the surface roughness in the workpiece can match that of the rolls (which can be polished). However, rolling at too low a speed has consequences such as:o Production rate will be low, and thus the cost per unit weight will be higher.

PDF A Basic Understanding of The Mechanics of Rolling Mill Rolls
Secondary scale on hot strip and the impact on wear is another issue. Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured years ago, the results were never published, but of high interest - also, maybe later. K. H. Schr"oder July 2003 K. H. Schr"oder: A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL ROLLS
PDF Energy Efficiency Analysis of an Industrial Reheating
called hot rolling because of requirement of large deformations. Hot rolling results in residual stress-free product. However, scaling is a major problem, due to which dimensional accuracy is not maintained. Cold rolling of sheets, foils etc are gaining importance, due to high accuracy and lack of oxide scaling.

The rolling mill that reduces a hot slab into a coil of specified thickness; the processing is done at a relatively high temperature (when the steel is still "red"). Hot Roll 1 Product that is sold in its "as produced state" off the Hot Mill with no further reduction or processing steps aside from being pickled and oiled (if specified).
Heavy plate mills (Steel) | SMS group
Each heavy-plate mill features its own individual layout. That depends on the product mix, the product geometries, and the installation site. Common to all mills are the main process sections: reheating furnaces, mill area with one or two reversing 4-high stands, plate cooling and hot plate leveler, cooling beds, shearing line, finishing line, heavy plate line, and heat treatment line.
Lubricating composition for hot-rolling steel - Nippon Steel
Disclosed is a lubricating composition for hot-rolling steel, which comprises a base oil or base grease and a heat-insulating agent. Especially, (A) an inorganic compound which is melted by an absorption of heat at a temperature lower than 1200° C. and (B) an inorganic powder which is not melted or decomposed at a temperature lower than 1200° C. and has a heat conductivity lower than 0.01
Hot Rolling - an overview | ScienceDirect Topics
When hot rolling steel in the laboratory, using relatively small rolling mills, values of 4-20 kW/m 2 K appear to be the correct magnitudes. If modelling hot rolling of steel under industrial conditions, values of 50-120 kW/m 2 K are more useful. In both cases, the layer of scale is an important parameter.
PDF Continuous casting and hot rolling
Hot-rolling o The first hot-working operation for most steel products is done on the primary roughing mill (blooming, slabbing or cogging mills). o These mills are normally two-high reversing mills with 0.6-1.4 m diameter rolls (designated by size). o The objective is to breakdown the cast ingot into blooms or slabs for subsequent

The problems rolling-mill rolls had at the time were "the short rolling pitch, which was compromised to improve productivity, and the increasing heat-load to the exterior surface of the roll." In 1988, Kubota invented the HIP Shaping Composite Ring Roll for steel bar and section mill, which was 10 times more durable than conventional rolls.
Stainless steel is used for buildings for both practical and aesthetic reasons. Stainless steel was in vogue during the art deco period. The most famous example of this is the upper portion of the Chrysler Building (pictured). Some diners and fast-food restaurants use large ornamental panels and stainless fixtures and furniture.
