Title:
PREDICTION METHOD FOR BEHAVIOR OF BLOOM CONTINUOUS CASTING REDUCTION SEGREGATION USING CONVEX ROLLER
Document Type and Number:
WIPO Patent Application WO/2020/181575
Kind Code:
A1
Abstract:
A prediction method for the behavior of bloom continuous casting reduction segregation using a convex roller, involving: first, accurately describing the bloom shell morphology of a bloom continuous casting process; then, accurately describing the bloom shell surface speed of the bloom continuous casting process; and finally, carrying out a multiphase solidification model coupling calculation. The prediction method is high-speed, high-efficiency and high-precision, and achieves a quantitative calculation for bloom internal macro-segregation behavior under various casting and reduction process conditions in the process of implementing continuous casting solidification end convex roller heavy reduction; and clarifies a mechanism for improving bloom solidification and segregation using reduction deformation in a convex roller heavy reduction process; and provides reliable theoretical support for the stable production of high-homogeneity casting billets.
