The purpose sought by installation of this line is to reduce the thickness of the sheet in the ambient temperature. After opening, the sheet passes though 5 four-rolled vertically positioned stands and reduces minimum 50 percent and maximum 85 percent of the sheet thickness and the sheet finally is coiled in the coiler unit. The product is the sheets 0.3 to 3 millimeters in thickness.

Temper Rolling. (also called skin pass rolling, or dressing), in engineering, a finishing operation in the production of thin strips of steel and nonferrous metals. It consists of cold rolling with very low reduction of area (not more than 3 percent). As a rule, the metal is subjected to temper rolling after heat treatment.
Temper Code Industry-standard code that indicates the hardness of the steel. Temper Mill A relatively light cold rolling operation that may be used on hot rolled, cold rolled and some coated steel such as galvanized. Temper rolling hot rolled sheet helps to improve flatness, minimize coil breaks and fluting and alter mechanical properties.
