conventional four – high mills, however, remain. 6Hi Reversing Cold Reduction Mill. Gives the work rolls adequate support at strip edges through the action of the intermediate roll on the back up roll so that strip shape can be preselected. Improves roll force distribution over .
The diameter of the 6high work rolls amounts to approximately 1:4 in relation to the barrel length. In comparison to a 4high mill stand, the utilization range is wider. This type of rolling mill is mainly used in offline applications for cold rolling of soft and medium strip and for a wide range of strip widths.
Tags Rolling Mills; 4High Rolling Mills. Fourhigh 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.
roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip recoil temperatures and interstand strip temperature rarely exceeding 160 oC depending on product. Roll Bite temperatures in slower heavily drafted stands can peak in the region of 300oC, diminishing with the
