Optimisation of the quality of continuously cast billets required for subsequent technological processing.

Optimisation technology of continuous steel casting,
ensuring billet quality for subsequent casting. Development
of original models and systems for the required assortment
and their verification in industrial operation at the ccm.

The project target is to optimise the continuous casting of steel technique that would ensure the required quality of ingots for subsequent processing. The original models and systems developed, specified and verified by experimental measurements on industrial continuous casting machines (CCM) for the commercial assortment, will be used to optimise the technology. The numerical program must solve a non-stationary 3D temperature field of the 'ingot-mould' system, or 'ingot-CCM ambience'. This requires the measurement of necessary values in the course of the continuous casting process and would enable us to obtain the data necessary for optimisation of the process of solidification and their projection into the calculating model. Data collected systematically from individual CCMs and technological data will be analysed by the developed methodology. In this way it would be possible to draw the solution most closely to the real conditions of the specific industrial operation and ensure the necessary inter-relationship between the chain 'real process-entry data acquisition-numerical analysis-optimisation-real process correction'. Samples would be simultaneously taken from cast slabs for subsequent analysis of heterogeneity of constitutive elements (Mn, Si, etc.) and impurities (P, S, etc.) in characteristic areas of the solidified slab. The results of the measurement with electron micro-probe would serve as basis for the determination of the distribution curves of dendritic segregation of investigated elements, as well as efficient element distribution coefficients between the liquid and solid phase. This approach would make it possible to evaluate in advance critical spots of slabs from the viewpoint of their increased susceptibility to crack and fissure formation. A system of quality prediction attested by the project proponents on the real CCM would be used for verification of the technological impact of the optimisation resulting from both models. Keywords: continuous casting, quality prediction, technological optimisation.
