Abstract
Disclosed is a light reduction method for continuous casting of a bloom plain-barrelled roll-roll combination. The method comprises: firstly obtaining three-dimensional temperature field profile, a two-phase region, solid-phase region thickness, and solid-phase fraction of a billet, determining positions of start and end rolls of the reduction, and setting a reduction amount of each tensioner roll according to the volume shrinkage of the billet; in an interval f=0.9-1.0 of the solid-phase fraction of the billet, performing a heavy reduction working mode; and in an interval f=0.25-0.80 of the solid-phase fraction of the billet, performing a light reduction working mode.
