Research on Mechanical Behavior of Casting Slab during Dynamic Soft Reduction

A three-dimensional dynamic solidification model incorporating the thermo-elastic-plastic coupling model has been proposed in this paper by ABAQUS considering the dynamic contact between the slab and rolls. The thermo-mechanical coupling model produces outputs such as temperature and mechanical behavior of the slab. And the stress-strain distribution of the high-temperature slab at the solidification end has been investigated in this paper. The influences of various reduction interval, reduction amount and reduction distribution on mechanical behavior of casting slab have been systematically discussed.
