Read MoreThe following six types of rolling mills are commonly used for rolling metals 1. two-high rolling mills 2. three-high rolling mill 3. four high rolling mill 4. cluster mill 5. multi-high rolling mill 6. universal rolling mill.
Read MoreThe two-high rolling mill consists of a two-high 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.
Read MoreAfter each pass, the direction is reversed. the metal piece is turned through 90, which keeps the section uniform and with fine grains. nearly 25-30 passes are required to convert an ingot into a bloom. the arrangement of two-high rolling mill is shown in fig. 2.9 a.
Read MoreThe three-high rolling mill consists of a three-high 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.
Read MoreIt is used for rolling of two continuous passes in a rolling sequence without reversing the drive. it has higher output rate than two-high mill. it is less expensive to manufacture. the arrangement of three-high rolling mill is shown in fig. 2.9 b.
Read MoreThe four-high 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.
Read MoreThis 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.
Read MoreIf such small diameter rolls are used alone, they will bend and result in non-uniform 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 four-high rolling mill is shown in fig. 2.9 c.
Read MoreThe 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 cold-rolling operation. the arrangement of cluster mill is shown in fig. 2.9 d.
