Rolling (metalworking) - Wikipedia

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.

The Hot Rolling Process

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.

Hot rolling mill process and hot rolled steel sections ...

Hot rolling begins with heating the billet or blooms to a high temperature of around 1100 degrees Celsius. The temperature is of particular importance. Hot rolling and hot extruding drawing involves working above the recrystallization point of the steel. The mill passes the heated material through a variable number of stands.

The PC mill was first used commercially for the continuous hot rolling mill of Hirohata, which was commissioned in 1984, and then for the former stands of the finishing mill train of the continuous hot rolling mill of Nagoya, and also for the finishing stand of the Kimitsu plate mill. 2.4 New rolling processes for long products

Progress in Sizing Press for Hot Strip Mill Line

of sizing presses in hot strip mill (hereinafter called HSM) lines. Originally, large-sized caliber edgers (sizing mills) with a bottom diameter of f1 200 mm were used for slab-width sizing, and their advantage with regard to material deformation brought about the emergence of caliber rolls with a very large diameter, f2 200 mm. IHI

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.

Simulation of deformation and temperature in multi-pass ...

Nov 15, 1997  A method of numerical simulation for hot caliber rolling is proposed, in which the deformation of material is analyzed in the conventional manner by three-dimensional rigid-plastic finite-element method (FEM), whilst the temperature distribution in the material is calculated using a combination of three-dimensional FEM and one-dimensional finite-difference method (FDM).

60 YEARS OF ROLLING MILL TECHNOLOGY By Ford B. Cauffiel

Rolling mills are not a standard machine tool, nor are they built for stock. They are designed and built-to-order to specifically accomplish an end product or process. At one point during the industrial revolution in America, the United States led the world in hot and cold rolling, plate mills, slabbing mills and blooming mills.

What Is A Rolling Mill? Metal Processing Machinery ...

Tags Rolling Mills; What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.

ROLLING - Primetals Technologies

By default, the strip width in a hot-strip mill is deter-mined by edging and rolling the strip in the roughing mill. The width deviation after the finishing mill arises from the width deviation in front of the finishing mill and from width-spread anomaly occurring inside the finish-ing mill. The behavior of width spread in a finishing mill

What is Hot Rolling - Advantages and Disadvantages

The rolling of metals above the recrystallisation temperature is called hot rolling. The temperature at which new grains are formed in the metal is known as recrystallisation temperature. This temperature should not be too high; otherwise the metal will burn and become unsuitable for use.
