Samples of refractory products based on metallurgical production wastes were obtained and studied at various ratios of components in a wide temperature range of 100–1650 °C. Their ultimate compressive strength (MPa), refractoriness, heat resistance, density (g / cm3) and shrinkage (%) were determined. A graphical representation of changes in the mechanical properties of fired refractories in the coordinates: ultimate strength in compression, MPa (σ) and firing temperature (T ° C) is presented.
