IOM3 Practical Roll Pass Design
In 2006 he was central to the Scunthorpe long rail rolling project with the development of the new Roll Pass Design for a seven stand continuous finishing mill. From 2009 to 2012 he was the Heavy Section Mill Process Director at Danieli and in 2012 became Manager Product & Process Development at Emirates Steel in Abu Dhabi.Roll Pass Design of TMT-32. Rolling of TMT-32 is same as rolling of plain round 32 mm, except higher metal is required to form lugs and ribs hi finishing pass. The area of finishing pass of TMT should be maintained same as that of plain round-32. Metal sizes of subsequent passes are required to be enhanced.Rolling Scheme of Round–32 mm, Roll Pass Design R-32 mm

Roll Pass Design and Simulation on Continuous Rolling of
Alloy steel round bar is designed to be rolled by the initial six passes of a continuous rolling process with alternatively arranged horizontal (H) mill and vertical (V) mill. The roll diameter for the first pass (H1) and second pass (V2) is 700mm and the other four passes (H3,V4,H5,V6) have the roll diameter of 610 mm.During the bar rolling, it undergoes sequential normal and transverse rolling known as per roll pass design. After the finishing, mill the bar is passed through the no-twist mill (NTM) having alternate arrangements of vertical and horizontal tungsten carbide roll stands followed by water boxes for controlled cooling for achieving the properties.Analysis of Chip Generation During Bar Rolling SpringerLink
