Abstract— According to research tests, the rolling-and-drawing of metal in nondriven rollers reduces the rolling force by 30 to 32% as compared with the rolling in driven rollers. A new method of determining the friction coefficient for a modified process flow sheet is proposed. As shown by the calculations, continuous strip mills used in the roll-and-draw mode …
