1. Introduction. The typical configuration of a four high rolling mill comprises four rolls: two work rolls (WRs) in contact with the strip to deform it and two backup rolls (BURs) supporting and transmitting the rolling forces [].BURs are normally produced of steel 5% Cr and quenched and tempered on the surface, obtaining a layer of hard material that is in contact with the WR.
Rolls used in metal rolling are of various sizes and geometries. In flat rolling processes, during industrial manufacture, the rolls may typically be 24 to 54 inches in diameter. In some metal rolling operations, in the forming of very thin work, the rolls can be as small as 1/4 inch.
Rolling mill definition, a mill where ingots, slabs, sheets, etc., of usually hot metal are passed between rolls to give them a certain thickness or crosssectional form. See more.

Rolling Mill Rolls. 1. Definitions. Rolls are a tool to produce plastic deformation of the metal. It is an important consuming part to determine the efficiency and quality of the rolling mill. Roll is an important part of the rolling mill. The pressure generated by a pair or group of rolls is used to roll the steel.
Rolling Mills Rolls. Rolling had assumed importance in the industrialized world during the nineteenth century. Rounds, profiles, and flats are hot rolled while some flat products are also cold rolled. ... 80 deg Shore for small backup rolls in cold rolling, and in the range of 90 100 deg Shore (fully hardened) for work rolls in cold ...
Twohigh Rolling Mills: This configuration is the most general rolling mill configuration. Two rolls are opposing each other. So, they rotate in different directions and the work part's thickness reduces. Nonreversing Rolling Mills: Actually, this type of rolling mill configuration is a type of twohigh rolling mill. In nonreversing rolling ...
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, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.
(3) The original cooling header design for F1F3 work rolls of Line 1580: F1F3 rolling mill outlet headers, the total water volume of existing F1F3 outlet headers is /h (/min): 1580 Line F1 F4 The spray watermarks of different rows of nozzles do not interfere, and the spray watermarks of the same row of nozzles on the roll do ...
Its main task is to consider how to improve the wear resistance and peeling resistance of the roll, and increase the depth of the hardened layer, so as to ensure that the surface structure of the roll is as uniform as possible, and improve the stability of the metal structure of the roll surface.

The advantages of Rolling process are as follows. By rolling, uniform dimensions of the components can be obtained. It uses the same tool in the sense, the same rollers are responsible for the production of various components. Close tolerance is possible for the components in the rolling. highspeed production takes place in the rolling.
Step 1: Heating Heat the steel ingots or billets to a temperature above their recrystallization temperature about 1,700 degrees Fahrenheit or higher. Step 2: Rolling Mill Machine Pass the heated steel through a rolling mill machine. The machine reduces its thickness and shapes it into the desired form.
For example, work rolls and backup rolls of hot strip mills; work rolls of medium and heavy plate mills; work rolls and backup rolls of skinpass mills; roll rings of section steel universal mills; Steel pipe rolling mill, continuous rolling of pipe rolls and reduction roll rings, etc.

Failure of ICDP rolls has been discussed in the present study. The F#5 stand bottom work roll was spalled in operation. Failure occurred after 448T of production in the last campaign. This failure resulted in h of breakdown in the mill. This roll failed after use of 90 times during the campaign in the mill.
