Starting materials such as blooms or slabs at an elevated temperature flow from the continuous casting process directly into the rolling mills.
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 of Metals • Rolling –reducing the thickness or changing the cross-section of a long workpiece by compressive forces applied through a set of rolls • Developed in late 1500s • Accounts for 90% of all metals produced by metal working processes • Often carried out at elevated temperatures first (hot

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.
May 02, 2017· Rolling process is most common industrial process used for making large length cross section like sheets and plates of steel and aluminum for structure and other works. Rolling mills are used to perform rolling process. These machines are available in different shapes and size according to requirement of the process and due to technical issues.
1.2 Rolling mills: Rolling mill consists of rolls, bearings to support the rolls, gear box, motor, speed control devices, hydraulic systems etc. The basic type of rolling mill is two high rolling mill. In this mill, two opposing rolls are used. The direction of rotation of the rolls can be changed in case of
In two high reversing rolling mills the rolls rotate ist in one direction and then in the other, so that rolled metal may pass back and forth through the rolls several times. This type is used in pluming and slabing mills and for roughing work in plate, rail, structural and other mills.
10 Tips on How to Use a Rolling Mill. Richard outlines how to use a rolling mill, and 10 ways a mill can be useful in your studio to help you be more creative. Here's how to use a rolling mill and some helpful tips: 1. Rolling mills can be used to roll a metal sheet into a thinner sheet, which will also work-harden it.
Various configurations of rolling mills: (d) cluster mill Cluster Mill 22 Variousconfigurations of rolling mills: (e) tandem rolling mill. Tandem Rolling Mill Rolling mills have several stages, where the each stage successively reduces the thickness of the stock until the desired cross section is achieved.
In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot– or cold–rolling or finishing mills. While some products (e.g. reinforcement bars, steel plates) only require hot-rolling, some others may require both hot– and cold ...
On the contrary, cold rolling is when the process is conducted at room temperature and does not require heating the metal. Learn more about cold rolling here. For Research and Development applications, FENN manufactures laboratory Rolling Mills equipped with Statistical Process Controls (SPC) to track and record "real time" data.

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.
