Rolling Scheme of Round–32 mm, Roll Pass Design R-32 …
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.

Pass Design of Blooming Mill, Defects in Bloom Rolling
The minimum width of barrel pass is determined by maximum width of ingot and slab. Suppose, ingot width is 785 mm, then the minimum width of barrel pass should be 100 mm more than the maximum width of ingot. The width of barrel pass also depends upon the maximum size of slabs to be rolled.

NUMERICAL SIMULATION IN ROLL PASS DESIGN FOR …
The 2.5 D technique was applied to the roll pass de-sign problem. The simulation results were used for ad-justing roll gaps to achieve the required bar shape and the uniform distribution of rolling force between the passes. Two roll pass designs were developed and analyzed: a classical oval-round roll pass design and a combination

Failure Analysis of Thermo-Mechanically Treated (TMT) …
During rolling pass overfilling is the most frequent cause of defect in rebars, when material is forced out into the roll gap metal folds over and is rolled into the rebar surface during subsequent passes in hot rolling stage which leads to crack during operation. In this present work failure analysis of failed rebar samples during bending ...
