Mathematical Optimization of Charge Compositions in the Production of Ceramic Bricks

The scheme of preliminary preparation, forecasting and experimental confirmation of the physicomechanical properties of ceramic products using the results of mathematical planning is developed. By the method of a full three-factor experiment, the influence of the main factors affecting the increase in the efficiency of studies on expanding the range of use of low-melting aluminosilicate loams in a composition with ash and slag waste (ASW) was established. The mathematical model of the experiment made it possible to establish the functional relationships between the recipe parameters (loam + ASW + silicate block) and the physicomechanical properties of ceramic bricks (density, compressive strength, water absorption). The regression equations are obtained, which allow to reveal the dependence of the response functions on the established factors. The response surfaces of the functions of the output parameters made it possible to visually assess the change in the properties of the full-body ceramic wall material using technogenic waste of the fuel and energy complex – ASW in the amount of 28% by weight in the composition with a silicate block of 10% at a firing temperature of 1050^оC and a pressing pressure of 20 MPa in the studied area of the factor space. The proposed experimental technique allows to ensure the stability of the production cycle when selecting raw materials and reducing the proportion of low-quality products and rejects.
