Inspection of Eqs. () and () indicates that force and/or power to roll a strip of a given width and work material can be reduced by any of the following: (1) using hot rolling rather than cold rolling to reduce strength and strain hardening (K and n) of the work material; (2) reducing the draft in each pass; (3) using a smaller roll radius

Hot and Cold Rolling Processes From metallurgical point of view, rolling process can be classified under two broad categories, namely (i) hot rolling and (ii) cold rolling. Hot rolling In hot rolling the material is rolled at a temperature higher than its recrystallization temperature. The advantage of hot rolling is twofold.

This concerns metal flow in the first few passes of the slab through the roughing train of a hot strip mill where the strip thickness is in the order of 200–300 mm and the work rolls maybe 1 m or more in diameter, leading to a roll diameter/strip thickness ratio in the order of 3–5.

Flow Chart Symbols. You''ll notice that the flowchart has different shapes. In this case, there are two shapes: those with rounded ends represent the start and end points of the process and rectangles are used to show the interim steps. These shapes are known as flowchart symbols. There are dozens of symbols that can be used in a flowchart.

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semifinished casting products, such as slabs, blooms, and billets.
