A suction roll is one of the most important process rolls and also one of the most costly rolls to maintain in a paper machine. By optimizing suction roll maintenance, a paper mill can reduce total maintenance costs, enhance roll reliability, lengthen service intervals and increase the total lifetime of the suction roll.
Abstract A new technique is developed to analyze the roll pass design of a section rolling mill. Metal forming nonuniformity and efficiency coefficients, which determine the degree of working of a metal microstructure in rolling of section bars, are used as performance criteria.

changes of roll pass design in Light Section Mill at Celsa Huta "Ostrowiec". This continuous mill consists of 25 stands arranged in 5 groups and is able for rolling in two strands. The schematic layout of rolling stands is presented in Fig. 8. Figure 1. Comparison of roll pass design for: a) conventional bar rolling, b) and c) rolling
Steel Mill Applications This section provides a number of steel mill applications for design and development engineers. We will gradually expand the range of applications from rolling to other metal forming processes, and eventually to the whole metallurgical/material engineering.
there are only few theoretical researches about the rail rolling by universal mills. Since the process ... So, present work is aimed at roll pass design of section rolling of rail section. 2. STANDARD RAIL SECTIONS AND ITS SPECIFICATIONS Rails are the members of the track laid in parallel lines to provide an unchanging, continuous, and
Roll Pass Design ispatguru. 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 .
