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.
The 2Hi Cold Rolling Mill are used for rolling of sheets, plates and coils of softer metals like Aluminum, Copper, Brass, Lead etc. to higher thickness (normally above 1 mm). We have manufactured more than 200 such rolling mills ranging from 50 mm width to 2000 mm width running successfully all over India and abroad.
Skin pass mill can be 2-Hi or 4-Hi structure, to improve the steel strip by S tensioning rollers and rolling mill. The flatness of cold rolled steel strip is not so good after annealing, skin pass line can largely diminish yield platform and improve the mechanical properties of annealed steel strips.

As the name suggests the 4 Hi mill employs 4 rolls, two these are the work rolls and the other two are the backup rolls. The rolls between which the cold rolling actually takes lace is called the work roll. The OD of the work rolls is between 208 to 225 mm or 145 to 155 mm, while the backup roll may be 575 to 610 mm.
Rolling mill consisting of four rolls or known as a 4 High rolling mill is used for reducing material to extremely small thicknesses. Through the use of larger backup rolls, the issues of roll deflection can be avoided and smaller work rolls can be used. This reduction in work roll diameter: Reduces overall separating force required for reductions
