Ribbon Fatigue Spalling of a Forged Work Roll Used at a …

 · Catastrophic failure of a forged work roll used in a cold rolling mill was investigated. The spalled roll showed fatigue arrest marks in a smooth continuous path along the circumferential direction. 11. W. Patt, in Production and Properties of High-Cr-Rolls and Their Behaviour in Cold Strip Mills, Conference Proceedings on Mechanical Working and Steel Processing, vol. XXII, The Iron and Steel ...

Rolling processes

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

Failure analysis of work rolls of a thin hot strip mill | …

Abstract In hot rolling mills, premature failure of rolls is a major concern as it adversely affects the mill operation as well as production. Analysis of failed roll materials and actual rolling conditions in service are therefore necessary to understand the roll failure mechanism and thereby improve the wear resistance and extend the service life of rolls. The hot strip mill referred here ...

 · In hot rolling mills, premature failure of rolls is a major concern as it adversely affects the mill operation as well as production. Analysis of failed roll materials and actual rolling conditions in service are therefore necessary to understand the roll failure mechanism and thereby improve the service life of rolls. The hot strip mill referred here consists of two stands in a roughing mill ...

Metal Rolling

The place where all the equipment for metal rolling manufacture is set up is called a rolling mill. Rolling mills often vary in the type, number, and position of rolls. Rolling mill arrangements commonly used in manufacturing industry today include the two high mill , the two high reversing mill , the three high mill , the four high mill , the cluster mill , and the tandem rolling mill .

Basic Of Rolling Operation and Nomenclature of Rolled …

In a rolling mill attached to a steel plant, the starting point is a cast ingot of steel which is broken down progressively into blooms, billets and slabs. The slabs are further hot rolled into plate, sheet, rod, bar, rails and other structural shapes like angles, channels etc,.

Some Basics of Rolling and Rolling Mills – IspatGuru

Rolling pressure – A useful quantity for characterizing the mechanics of the rolling process is the average normal stress, pressure, acting between the work and roll. The pressure is not constant since the stress acting to deform the work material is the stress needed to overcome material strength, overcome frictional forces and overcome any constraints placed on the deformation by process ...

[PDF] Application of Ultrasonic and Eddy Current Testing …

 · The work rolls used for hot and cold rolling of steel strips are subjected to severe mechanical and thermal stresses resulting in rolling contact fatigue, wear and plastic deformation on the roll bodies. The arduous service condition often leads to generation of thermal and mechanical cracks on roll surfaces and may vary from micro to macro levels in the form of discrete or continuous networks ...
