Metal-Rolling - Flat-rolling process Fig 13.3 various roll arrangements: (a) two-high mill; if a two-high mill is used for thick but short workpieces, it will commonly roll a billet back-and-forth in multiple passes, known as a reversing mill. (b) three-high mill with elevator for multiple passes. (a) (b) Roll arrangement

u3-HiGH ROuGHiNG MiLL At precisely the right moment, your billet emerges from the furnace and moves to the rolling mill bed. Tilt tables in the mill floor raise the billet to enter the top two rolls of the roughing mill. In a pulpit above the rolling mill floor, the operator positions your billet for reduction in the three-high heavy roughing mill.

In this paper, a real application of opti- mal control of a hot rolling mill is presented. It is used the state space model formulation in the minimization of the strip thickness variations.

the hot rolling mill is coiled for transport to the cold mill which might be on the same site or elsewhere. Cold mills, in a wide range of types and sizes are available; some are single stand, others 3 stand and some 5 stand (Figures 1301.02.03 and 1301.02.04). Cold rolling speeds vary but modern mills operate at exit speeds as high as 3000 m per

The layout of a rolling mill varies, from a simple single stand mill to several stands positioned either side by side or in a line. A mechanism, commonly called a roller table, directs the work piece to the rolls, and another roller table for handling the pieces emerging out of the roll. The table in front of the rolls forces the steel

Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. Under rolling conditions the contact area between roll and stock suffers wear, the other parts of a roll - body and necks - have to be considered as normal parts of designed components under high

During manufacturing of heavy strips and plates from difficult-to-form steel grades on sheet and wide-strip rolling mills there is a problem of exact calculation of power parameters of rolling.

Reducing the roll gap increases the roll pressure to p3. Gage control in multiple rolling mills is achieved through measurement of strip thickness using x-ray gage and adjusting the strip tension using feedback control system. 1.8 Rolling defects: Mill spring is a defect in which the rolled sheet is thicker than the required thickness because,

rolling mill thus helps in reducing the size of a metal thereby molding it into the desired form and shape. Rolling mills perform the function to reform the metal pieces such as billet and ingot whilst maintaining its well equipped micro structure into bar, wire, sheet, strip, and plate. Hot rolled products are

Today’s rolling mills. The basis of design for today’s equipment is not too dissimilar to early designs, particularly when you consider a basic 2-high mill. It just uses different types of materials and designs of roll stacks. However, today’s mills are now designed for processing a multitude of metals for extensive end-user applications.

after rolling. In practical the volume might decrease a little bit due to close-up of pores. 5) The velocity of the rolls is assumed to be constant. 6) The metal only extends in the rolling direction and no extension in the width of the material. 7) The cross sectional area normal to the rolling direction is not distorted.
