A 4-high-rolling mill includes a pair of upper and lower work rolls (1, 2), a pair of upper and lower backup rolls (21, 22) supporting the upper and lower work rolls, respectively, a roll bending device (11, 12) for applying a bending force to the upper and lower work rolls, and a roll shift device (9, 10, 16) for shifting the upper and lower work rolls in an axial Intermediate rolls positioning Sketch 10 is of a 6 high mill showing the position of the intermediate rolls. In the 6 high mill shown in sketch 10, the roll between the work roll and the corresponding back-up roll is called an intermediate roll. These intermediate rolls have the ability to move horizontally slightly into or out of the mill stand.Tandem rolling mill

Spatial Vibration Characteristics of Four-High Rolling Mills
The theory of micro dimensional behavior on rolling mill is used for a typical 450 mm hot plate four-high mill. A statically determinate device is adopted on the back-up roll system to adapt toBased on the direction of feed available, two high rolling mills are further divided into types :-a) Non -Reversilng two high rolling mill In this type of rolling mill, the rolls can rotate in one direction only and hence the workpiece can be feeeded from one direction only.b) Reversilng two high rolling mill In this type of rolling mills, the rolls can Types of Rolling mills With detailed information

Sundwig S6-high cold rolling mill Andritz
A special feature of Sundwig S6-high rolling mills are the side-supported work rolls. The patented Sundwig S6-high side support stabilizes the work rolls in this type of mill stand using mechanical, hydraulic lateral support equipment, thus preventing lateral excursion of these rolls. The diameter of the S6-high work rolls is only approximatelyFig 1 Components of a roll stand. Housing Housing creates a framework of the rolling mill stand and for absorbing the total metal pressure on rolls during the process of rolling. Hence, the housing is to be solid and its structure is to enable easy and fast roll changing. Also, there need to be easy access to all parts of the housing and Rolling Mill and its Technological Equipments IspatGuru

Our half-a-million ton per year range rolling mills provide the best performance-to-price ratio on the market. The rolling mill stand has sprayingThere is evidence for rolling of lead and tin on simple 2-high mills with cast-iron rolls at the beginning of the seventeenth century. At this point rolling mills did not process the high volumes of metal that we see today. In addition, the required quality of these early products was ‘poor’ if we measure it by today’s exacting standards.A brief history of metal rolling for sheet and plate products.

Rolling in Nondriven Rollers of Four-High Mill Stands
Abstract— According to research tests, the rolling-and-drawing of metal in nondriven rollers reduces the rolling force by 30 to 32% as compared with the rolling in driven rollers. A new method of determining the friction coefficient for a modified process flow sheet is proposed. As shown by the calculations, continuous strip mills used in the The mill is capable of reverse-rolling blooms weighing up to 16 t to widths of between 580 and 840 mm and thicknesses of 8.5 to 25 mm. The reversing cold mill is a 4-high type. Superior design and actuators for roll gap setting 20-high mill technology SIEFLEXFlat rolling mills for copper SMS group GmbH
