Abstract Scope |
Harsh environments in the continuous casting of steel prevent most types of in-situ measurement and observation techniques. Slight local disruptions to the desired uniform thermal and mechanical conditions within the mold often lead to solidification defects. These defects are often only discovered in the process far down-stream from the origin point within the mold. A new methodology has been developed to elucidate the formation mechanism of these defects within the mold region using only the final shape of the defect on the cast slab. Using a thermal-mechanical finite element model conditions within the mold are simulated and loading conditions that mimic caster behavior are imposed. The general shape of the defect is found to vary with disruption severity and loading type, creating distinctly different types of longitudinal defects; additionally the presence of different sizes and types of cracks also dramatically affects the development of the defect. |
