The history of the Sundwig 20high rolling mill begins in the first half of the last century when Sundwig developed a multiroll cold rolling mill in 1930 Just a few years later the first alligatortype 20high rolling mill was built followed in 1958 by the first 20high rolling mill in Sundwig Four Column SFC design Since then ANDRITZ Sundwig has continued to develop 20high rolling mill technology consistently and ranks among the leading manufacturers in this field.
Jul 28 2020nbsp018332In this tandem mill types of rolling mill It includes of a number of nonreversing twohigh rolling mills provide one after otherSo that the material can be passed through them all in order This is only suitable for mass production work as lower volumes require a quicker change of set up and they will consume a lot of labour and work.
The rolling mill stand houses all of the stateoftheart flatness adjustment elements like tilting bending and axial shifting The highimpact strip drying system ensures a safe rolling process up to the maximum rolling speed.
The fully automatic roll change by robot has substantially shortened rolling mill setup times and even more importantly permits contactfree roll changing within a very short time without damaging the rolls.
With more than 135 references for 20high cold rolling mills Sundwig is one of the most notable suppliers in this rolling mill technology segment.

The following six types of rolling mills are commonly used for rolling metals 1 TwoHigh Rolling Mills 2 ThreeHigh Rolling Mill 3 Four High Rolling Mill 4 Cluster Mill 5 MultiHigh Rolling Mill 6 Universal Rolling Mill.
The twohigh rolling mill consists of a twohigh stand with two horizontal rolls placed exactly one over the other In this type of mill one or both the rollers are adjustable In its operation the metal is passed between the two rollers rotating at the same speed but in opposite direction.
After each pass the direction is reversed The metal piece is turned through 90 which keeps the section uniform and with fine grains Nearly 2530 passes are required to convert an ingot into a bloom The arrangement of twohigh rolling mill is shown in Fig 29 a.
The threehigh rolling mill consists of a threehigh stand with three rollers placed in a single vertical plane The upper and bottom roller rotate in the same direction whereas the middle roller rotates in the opposite direction.
It is used for rolling of two continuous passes in a rolling sequence without reversing the drive It has higher output rate than twohigh mill It is less expensive to manufacture The arrangement of threehigh rolling mill is shown in Fig 29 b.
The fourhigh rolling mill consists of four rollers two of which are working rollers small diameter and the other two are backing up rollers larger diameter The all four rollers are arranged above one another in a vertical plane Also the backup rollers always have larger diameters than those of the working rollers.
This type of rolling mill is used in sheet rolling To reduce the rolling force F of the metal on the rolls and the power requirement it is suggested to design rolls as small as possible.
If such small diameter rolls are used alone they will bend and result in nonuniform thickness distribution along the width of the sheet For this reason another pair of two backup rolls are used to minimize bending and deflection of small working rolls The arrangement of fourhigh rolling mill is shown in Fig 29 c.
The cluster mill consists of two working rolls and four or more backing up rolls The number of backup or supporting rolls depends upon the amount of support required for the working small diameter rolls Cluster mill is generally used in coldrolling operation The arrangement of cluster mill is shown in Fig 29 d.
The whole bar rolling mill line adopts full continuous rolling and nontwist rolling and the roughing mill and intermediate mills adopt microtension rolling After the 12th rolling mill vertical loopers are set up between the stands to implement tensionfree rolling thus producing highprecision products.
