The mill contains 320 mm diameter working rolls, with 500 mm barrel length. Rolling was executed at 15 m/min. rolls velocity. A pass design was constructed for the finish hot rolling stage. The design consists of 5passes for thickness reduction from to mm.
Rolling is a wellestablished forming process employed in many industrial sectors. Although highly optimized, process disruptions can still lead to undesired final mechanical properties. This paper demonstrates advances in pass schedule design based on reinforcement learning and analytical rolling models to guarantee sound product quality. Integrating an established physical strengthening ...
As much as 1520% of GDP of industrialized nations comes from metal forming industry. Roll pass design It is a set of methods for determining the dimensions, shape, number and type of arrangement of rolling mill passes. It also includes the calculation of pressing forces and their distribution on the roll passes.

This book discusses as well the different types of rolls for various rolling mills, including blooming, plate, sheet, sheet bar, small section, heavy product, skin passing, and cold rolling mills. The final chapter explains the purpose of roll pass design to ensure the maximum output at minimum cost as well as to reduce the roll wear to a minimum.
Factbox 1 ABB and rolling mills Footnote 1) A pass is one deformation step consisting of the different phases threading, rolling at constant speed, deceleration and tailout of the strip through the mill. A pass schedule is a series of values for the pass, such as thickness, speeds and forces presets.
It is a combination of software and hardware design concept. Eight optimization steps pass schedule generation, work roll determination, backup roll diameter, mill type selection, mill window ...
WICON is a software that can be used in all levels of the company for this type of analyzes. With WICON software you can: Optimize setup of the rolling mill. Calculate process parameters. Automatically generate pass design. Create roll and groove drawings. Complete analyze of the rolling mill. The investment in the WICON will be paid off in a ...
The roll pass design proposal takes into consideration the lower plasticity of certain steels. Another special requirement was the shortest possible work length of the rolls. The standard odd number of passes was used because of the presumption that the roll pass design is a preparatory sequence of the laboratory rolling mill.

If the mill rolls 800,000 tons per year, it runs at an average production rate of tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x =, creating extra rolling hours. At tons/hour that is an additional 10,000 tons can be rolled.
Roll pass design (RPD) is a principal factor that determines process efficiency, product quality and resource consumption. Therefore, it is important to optimise RPD including the selection of...
