Studies on the Work Roll Life and its Materials of Hot Strip Mill Roughing Stands

Abstract

This paper presented some experiences of work roll life and roll materials of hot strip mill roughing stands in the Chiba Works of Kawasaki Steel Co. First we tried the similar roll materials as slabbing mill for the two high roughing stand. After tried several typcs of roll such as alloy cast steel and ductile cast steel rolls, we find the work roll conditions are much more severe than the slabbing mill. Either double poured cast steel rolls or light forged adamit cast steel rolls has been used now, and having relatively long work roll life.
Similar trials were done for the work rolls of four high roughing stands, and high hardness adamite cast steel work rolls has been used.
