Evaluation of C(t)-integral for inner cracks of steel slab during reheating process Lee, Kang-Yong; Kim, Jong-Sung; Lee, Hyo-Jin; Park, Sung-Ho;
The crack problem of continuous casting slab due to the thermal stresses during the reheating process is analyzed using FEM. In this study, the C(t)-integral is calculated. As a result, the values of the C(t)-integral decrease by increasing the initial temperature of the slab and decreasing total heat flux. And those decrease by decreasing the heat flux of pre-heating zone and increasing the heat flux of heating zone.
