P. P. ROLLING MILLS MFG. CO. PVT. LTD. TradeIndia. Roll pass design is a set of methods for determining the dimensions, shape, number, and type of arrangement of rolling mill passes. Roll pass design also includes the calculation of pressing forces and their distribution on the roll passes. Several passes are made for each section; a square or round billet or bloom acquires a specified form on each successive pass. The roll passes are designed, hot strip rolling line. Their main task is to coil the strip out of the finishing mill, and then transport to the next working procedure. The core part of coiling control system is the tension.

rolling mill is very difficult, especially for a hot rolling mill. To meet the need of practical production for the rolling process, simulating investigation for high temperature rolling process is a feasible method for roll wear study. a rolling mill to reduce its cross-section (Figure 4). A rolling mill consists of a series of stands, each of which consists of two cylindrical rolls into which grooves are cut to accommodate the material being rolled. The sizes of the grooves are progressively reduced through the mill, so that the cross-sectional area of the product is continuously reduced as it is rolled. Hot rolling is a
