Section Rolling Mill. Rolling mills are facilities that carry out a series of processes including rolling the billets, blooms, slab and beam blanks – extracted from the reheating furnace – into the prescribed size and correcting any bending, cutting them into given lengths, …After the foil section on the forming table, the moving fabric passes over a series of vacuum boxes and then over a couch roll. Often, a dandy roll is located on top of the forming fabric over the suction boxes. This is a light open structured roll covered with wire cloth, resting lightly upon the surface of the sheet. Its function is to flatten

A typical example is TS6x4x1/4 where TS = Tube Steel, 6 and 4 are the actual width and depth in inches, and 1/4 is the wall thickness in inches.

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.mill showing various features. The stiffness of the housing, the rolls, and the roll bearings are all important in controlling and maintaining the thickness of the rolled strip; (b) two-high mill; (c) three-high mill; and (d) cluster (or Sendzimir) mill. Consequently, …

A suction roll is one of the most important process rolls and also one of the most costly rolls to maintain in a paper machine. By optimizing suction roll maintenance, a paper mill can reduce total maintenance costs, enhance roll reliability, lengthen service intervals and increase the total lifetime of the suction roll.ed by the die, and/or by post-extrusion forming, and then the product is set to shape by cooling it while maintaining its shape. The equipment that does this is called the post extrusion equipment, while the whole system is called an extrusion line. Extruder Classification Extruders may be classified by three figures, for example, 1-60-24. The ...

Roll forming, also spelled roll-forming or rollforming, is a type of rolling involving the continuous bending of a long strip of sheet metal (typically coiled steel) into a desired cross-section.The strip passes through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired cross-section (profile) is obtained.Calculating the length of a roll. If you take a cross-section of a roll, it forms an annulus. If you lay the material flat, this cross-sectional shape will be a long thin rectangle. These two shapes will have equal areas, and this is the key to finding out the length of your roll. Look at this image:
