The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
Reheating furnace for steel rolling mill line is a device (an industrial furnace) that heats a material or a workpiece (generally a metal) to rolling forging temperature in the metallurgical industry.. Structure and composition. According to the distribution of furnace temperature, the furnace is divided into preheating section, heating section and heating section along the length direction.
The most common configuration is the single reversing mill. Various mill designs are offered that include 6-high UCMs (Universal Crown Control Mill), ZR mills and 12-high cold-rolling mills with small-diameter work rolls for the efficient rolling of materials of high hardness.
Taguchi Method is a statistical approach to optimize the process parameters and improve the quality of products that are manufactured. This paper focuses on initial study of rolling parameters of cold rolling mill and its optimization of process
Multi-roll cold rolling mills are used to process high grade steel strip and non-ferrous metal strip. In order to prevent whipping of the work rolls, they are supported by means of intermediate rolls and support shafts. Several back-up rollers are arranged
strongly depends on hot rolling parameters such as strain, strainrate, temperature,groovedesignandrollingsequence. It inﬂuences the metal deformation behaviour within the pass and mill load requirement apart from roll wear. The metal ﬂow behaviour in a hot rolling process is a complex phenomenon, which is complicated due to tensorial stress
May 30, 2013· Some Basics of Rolling and Rolling Mills . ... The above 14 parameters may singly or jointly, in combinations of two or more, create secondary parameters anf phenomena more directly related to and commonly associated with the rolling process. These are given below.
only under so called “normal rolling conditions” and even these change continuously with progressive wear in the contact zone. Besides “normal rolling conditions” - a stable, theoretical assumption - mills experience many different changes in rolling conditions. After a roll change or a mill stop rolls need some time to return to stable
Nov 27, 2015· Understanding Rolling Process in Long Product Rolling Mill ... Major parameters in the three stages of mill processing are as follows. Reheating – The input material usually billet is heated in the reheating furnace to the rolling temperature. The important parameters are heating rate, time of heating, and temperature of reheating.

Do you know all of the specific mill parameters that contribute to productivity, quality and yield at your long product rolling mill? How many automated control point solutions are leaving you with disconnected data, people and processes? Manual monitoring is unrealistic due to the large number of data sources and process variables.
1 HOT ROLLING PRACTICE – An Attempted Recollection Saral Dutta. B. Tech. (Hons.), I.I.T. Executive Director, ISP & RMD, SAIL (Retired) Rolling is a metal forming process in which metal stock is passed through a pair of rolls.

mill. Some of the key AGC input parameters are speed and tension. (See Figure 1) Conservation of mass dictates that the mass per unit time entering the mill must equal the mass per unit time exiting the mill. So as the material is rolled thinner, the speeds must ... Optimization of a Cold Rolling Mill ...
A tandem mill is a special type of modern rolling mill where rolling is done in one pass. In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18.

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.
