breast roll, couch roll, suction boxes, wire rolls, and other parts. The fabric on which the sheet of fibre is formed is a finely woven synthetic fabric of strands made of specially fine drawn and filaments, woven into a screen. Various types of weave are used to obtain maximum fabric life and to reduce wire marking on the wet sheet.
High-carbon high-speed steel rolls (referred to as high-speed steel rolls) are the hottest roll materials with the shortest development time, the fastest development and the most promising applications. Since its inception in Japan in 1988, it has been widely used in hot rolling mills, hot strip mills, cold strip mills, steel tube mills, section mills and bar and wire mills.

how much faster the slab exits the roll bite compared to the roll surface speed. It is expressed as a percentage of the roll surface speed and it is easily measured on a mill. Two-dimensional FEA simulations, such as the one in Fig 3, can be used to calculate the forward slip. From the results, analytical expressions can be derived for
cold rolling mill is of the type where shifting of both first intermediate and inner second intermediate rolls are possible. The rolls are numbered and defined as: 1. Work roll, diameter between 50-75 mm. 2. First intermediate roll (tapered), diameter between 90-105 mm. 3. Inner second intermediate roll (CVC roll), diameter between 177-182 mm. 4.
