Abstract

In this work, a curved surface convex roll (CSC-Roll) suitable for wide-thick slabs was designed. According to the field conditions and casting parameters, a 3D thermal-mechanical coupling model of CSC-Roll reduction was established, and the uneven solidification morphology of the slab was obtained. By analyzing the liquid core deformation rate, surface maximum stress and reduction force of the CSC-Roll with different shape parameters, the optimal shape parameters of the CSC-Roll were designed. By coupling the shrinkage void in the 3D thermal-mechanical coupling model, the coalescence degree of shrinkage voids under the flat reduction is calculated to be 8.78 pct, and that under CSC-Roll reduction is 9.68 pct, and the deformation degrees of the shrinkage voids in different directions were compared. The critical strain of slab surface crack propagation measured by high-temperature tensile test is 0.181. Based on the relationship between crack tip strain and initial crack length during reduction, the critical initial lengths of longitudinal and transverse crack propagation on slab surface were obtained to be 15.7 mm and 28.0 mm.
