Abstract— According to research tests, the rolling-and-drawing of metal in nondriven rollers reduces the rolling force by 30 to 32% as compared with the rolling in driven rollers. A new method of determining the friction coefficient for a modified process flow sheet is proposed. As shown by the calculations, continuous strip mills used in the …

Four-high-rolling-mill. Small diameter rolls (less strength and rigidity) supported by larger diameter backup rolls. It consists of four rollers. This process is used for both cold and hot rolling. Cluster rolling mill or sendzimir rolling mill: Each of the working rolls is supported by two backing rolls. Here rigidity is well maintained.

4-High Rolling Mills. Four-high rolling mills can be put in tandem, two to seven stands, instead of a reversing mill. They can be equipped with load cells to tell the separating force and hydraulic or mechanical screw downs, depending if it is hot or cold rolling. Sometimes mechanical screw downs are preferred when there is a risk of fire.

Temper rolling is used to eliminate flatness defects and improve the flatness of the strip, which is the last step for correcting strip flatness before consumer use. A hot-rolled temper mill is usually a single-stand four-high rolling mill, which has fewer flatness control methods.

Roll necks In most cases, inner rings of four-row cylindrical roller bearings in back-up and work roll applications are mounted on the roll neck with an interference fit. Recommended roll neck diameter tolerances are shown in table 1 . For a good fit, SKF recom-mends aiming for the upper limits of the tolerance range (maximum metal condition).
