I summarizes the typical thicknesses and rolling speeds for each mill type. Not surprisingly, as the material gets thinner, the speeds increase dramatically. Hot Roughing Mill Hot Finish Mill Cold Rolling Mill Maximum Thickness > 400 mm 20-50 mm 3-20 mm Minimum Thickness 20-50 mm 3-20 mm 0.100 mm Rolling speeds (meters per min) ~ 100 ~ 1000 …
Then with the help of a rolling conveyor, these billets are made to pass through 1 stand i.e.Roughing stand. Temperature prior to rolling is also monitored by St optical pyrometer. This begins the process of gradual size reduction of billets. Following roughing mill, the size is further reduced in intermediate & finishing Mill.

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size, and the gap between the rolls and their contour. Because of workability and …
The slit rolling process differs from conventional continuous rolling by the use of special roll pas- ses and guides to prepare, shape and longitudinally separate the incoming billet …
The strict periodicity of the repetition is a clue to look for a damaged roll. Remember, the bar is moving longitudinally at miles per hour speeds toward the end of the rolling, so any contact with the soft metal by rolling mill guides etc, will cause a longitudinal oriented imperfection because of that speed.

This obviates the transport of material from one side of rolls to the other after one pass is over. 3. Four High Rolling Mills. Four High Rolling Mill. As shown in the above figure, this mill consists of four horizontal rolls, two of smaller diameter and two much larger ones. The larger rolls are called backup rolls.
Guide rollers, one of the main parts of ring rolling machine, are controlled by a hydraulic adjustment mechanism. The typical guide roller adjustment mechanism is shown in Figure 11. It is symmetrical about the symmetry plane of the ring rolling mill and comprises two parts: linkage assembly and hydraulic ram. The guide roller arms rotate round ...
