In general in tandem cold rolling mill / two-stand cold reversing mill the stands can be of 4- high type or 6-high type (i.e., stands with 6 rolls). The single stand cold reversing mill process can be achieved (in particular for stainless steel) with stands of 20-high type also known as cluster mill or Sendzimir mill. Strip shape measurement system
The purpose of the reversing mill is to reduce the thickness of the steel to the customer's specifications. The hot roll band passes back and forth between the rolls until it reaches the specified thickness. Benefits of reversing mills include: Flexible, low-cost rolling of a wide range of products. Tight strip thickness and shape tolerances.
With intermediate roll shifting and horizontal roll stabilization, it is designed for high production of wide and thin gauge strip with superior thickness and flatness tolerances. Available features include: Automatic Flatness …
The cold rolling mill is usually fitted with thickness gauges that check the steel as it comes out of the rollers. Reversing mills are designed so that the steel can be reversed and pushed back through the rollers which are brought closer together each time until the desired thickness is achieved. ... Due to the high compression forces and ...
Thus, this paper presents the effects of various work roll contours designed for (1) the 6th and 7th stand of a 4-high hot tandem rolling mill; (2) single stand 6-high reversing cold mill; (3) 1st to 3rd stands of a 6-high tandem cold mill.

4.INTRODUCTION When sheet is entered between a pair of rolls and any kind of force applied to that sheet, like that generated when making a reduction, the rolls, since they are supported at the roll ends, will bend around the sheet. This will tend to make the sheet relatively thick in the middle and thin on the edges. On thin sheet, this will be seen …
