Designing the physicochemical properties of consumables used in the steel industry must be adapted to the technical and technological parameters of production equipment. Proper design of the properties of the consumables used in the production line allows for high-quality final product.The article describes the use of a model for the design of the physicochemical properties of mould powders that meets the requirements of the local conditions of technological equipment CC based on the developed in recent years empirical rule. The model determines the physicochemical properties of the mould powder based on established procedures and consecutive logical steps, which include solving issues such as the proper classification of cast steel to a group of species, optimizing the parameters of the oscillation and lubrication conditions for the selected cross-section of the mould and to determine the optimal values of the three physical parameters of slag mould: basicity, viscosity, and crystallization temperature (breakthrough). The final composition of the backfill is fixed as a result of multiple calculations the aforementioned. Physical quantities, until the results of the most similar to the values assumed. Preliminary calculations indicate that the model correctly determines the chemical composition of the backfill for carbon steel and low-alloy cast at standard speeds in slabs.
