Study of physico-chemical properties of refractory materials synthesized from metallurgical waste

The aim of the research was to investigate the utility of components of metallurgical wastes in the production of high temperature refractory bricks based on rich and poor chromium spinel powder (HSP) waste produced by self-propagating high-temperature synthesis method. The series of experiments on the obtaining of carbon containing refractories based on the waste of rich and poor chrome spinel powder were conducted in a muffle furnace. The effect of the adding of rich and poor chromium waste on refractories’ mechanical and thermal properties were detailly studied. Thermodynamic calculations and thermochemical modeling were performed between the components of metallurgical waste using the HSC Chemistry software. The diagram and graph were constructed that demonstrate the possibility of forming high quality refractory materials under experimental conditions using calculation modules. The compressive strength value of obtained sample was at competitive level in accordance with series of mechanical tests.
