Abstract [en]

In order to study the central quality of continuously cast tool steel slabs, the mathematical model has been developed to simulate the quality criteria. The model calculates different quality criteria such as average macrosegregation level criterion "ASL", its average fluctuation level "FSV and its average segregation quality number "SQN" of different segregated elements. These criteria were calculated based on the previous measurements in central areas of lower and upper slab sides. These measurements of carbon and sulfur concentrations were performed by chemical analysis technique. The effect of mechanical soft reduction technique "MSR" on the central quality of slab was also examined and studied. The model predications illustrated that this technique affects the centerline quality significantly by different ways based on the casting speed. These predications pointed out also that the macro-segregation quality criteria and their distributions can be considered as the most simple and important tools of steel industries men to explain preventive techniques and formation mechanisms of different defects in slab central area.
