Document Type and Number:
WIPO Patent Application WO/2020/042924
Kind Code:
A1
Abstract:
Disclosed is a light reduction method for continuous casting of a bloom plain-barrelled roll-roller combination. The method comprises: firstly obtaining three-dimensional temperature field distribution, a two-phase region, solid-phase region thickness, and solid-phase fraction of a billet, determining positions of start and end rollers of the reduction, and setting a reduction amount of each tensioner roller according to the volume shrinkage of the billet; in an interval f s＝0.9-1.0 of the solid-phase fraction of the billet, performing a heavy reduction working mode; and in an interval f s = 0.25-0.80 of the solid-phase fraction of the billet, performing a light reduction working mode.
