Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel's recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can .
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.
production scheduling on the hot rolling mill. 2. HOT ROLLING 2.1 The process The hot strip m ill typically consists of several processing stages (reheating furnace, roughing mill, finishing mill, down coiler), on which the slabs need to be processed sequentially ; see e.g. Lenhard, J.G (2007) and Ginzburg V.B. and Ballas R.
Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham, England. In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was the first to ...

The Hot Rolling Process - California Steel Industries. 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.
Rolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.
Rolling processes date back to 1779. The first rolling mill was built in Fontley, Hampsire where Henry Cort developed and received patents for his ideas. The two types of temperature-dependent rolling processes are hot rolling and cold rolling, and they each have their own specific use. Hot Rolling

Two types of rolling mills can manufacture ribbon from aluminum alloy slabs ... Miller and Smith (1979) chose to hot-roll the input slabs, which, therefore, ...
Cold rolling involves a similar process to hot rolling, however the steel is subjected to further processing. After being rolled, the steel is cooled at room temperature in cold reduction mills. After the steel has cooled, it is subjected to annealing and/or tempers rolling, in order to provide a wide range of surface finishes and more accurate dimensional tolerances.

NOTE: Hot-rolling and cold-rolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hot-rolled or cold-rolled. HOT-ROLLED STEEL. Hot-rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F.
It is the heart of any hot rolling mill. Reheating of steel is a continuous process. Combustion at an air/fuel ratio slightly above 100 stoichiometric results in a small percentage of oxygen ... No matter which paste must be processed the EXAKT three roll mills can break open all kinds of agglomerates.
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 semi-finished casting products, such as slabs, blooms, and billets.
Mar 27 2014 · Rolling can be done either by hot rolling or by cold rolling. Cold rolling usually follows the hot rolling. During hot rolling of steels the cast grain structure of steel achieved during the steelmaking process (usually large grains grown in the direction of solidification) is converted into a wrought grain steel structure.

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.
