Paper Title:
Thermal-Mechanical Analysis for Surface Cracks on FTSC Slab
  Abstract

Calculation of steel solidification in H2 mould of FTSC with Two-dimensional thermal- mechanical coupled method, results show that steel in mould has a wide two-phase region which grows rapidly during solidification, so columnar crystal and coarse grain were well-developed. Stress calculation results show that internal tensile stress reach to 13-17MPa in two-phase region, and the closer to shell surface, the greater of SEQV. It has the condition for microcracks generation and growth in Mould. Control heat transfer in mould can uniform temperature distribution, thereby reduce stress and enhance the plastic property of shell.
