steel is having 20 Hi and 4 Hi rolling mills, chiefly the mill is being decided along with the thickness of the strip, the thinner (2 to 3 microns) sheets can be produced by 20 Hi rolling mill whereas the more thick sheets can be produced by 4 Hi or 6 Hi rolling mill (4 to 10 microns).
The 2 Hi Cold Rolling Mill is used for making strip/sheets and helps in improving the strength and forming higher tolerance. This machine provides accurate size and output desired by clients and advanced methods of production which directly reflect in higher productivity and reduce the operational cost significantly.

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.
Rolling processes 51 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (51). Fig. (51) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.
2Hi Mills Hot, Cold Temper Mills. Designed for hot or cold rolling of ferrous and nonferrous metals, these 2Hi mills are ideal for breakdown, run down, tempering and skin pass operations. All mills are built to customer specifications, with rolls of forged steel, cast .
