During hot-rolling,the steel achieves high speed,for example,finishing speeds as high as 4,000 feet per minute in a bar mill and 10,000 feet per minute in a rod mill.The high speed at which the steel is hot-rolled is one of the reasons it has been deemed impractical,if not impossible,to treat the steel during hot-rolling.Metalworking Glossary - KLINGSPOR Abrasives,Inc.A solid semi-finished round or square product that has been hot worked by forging,rolling,or extrusion.An iron or steel billet has a minimum width or thickness of 1 1/2 in.and the cross-sectional area varies from 2 1/4 to 36 sq.in.
