Conclusions We studied the effect of the additives (silicon carbide, boron nitride, and chromite) on the physical and mechanical properties of a high-alumina ramming body, It was established that chromite additions significantly improve the properties of the body. The optimum composition of the high-alumina body based on the ÉB-50 electrocorundum (73%) and the ShMK-77,5 mullite-corundum chamotte (27.0%) containing 10% chromite additive was developed using orthophosphoric acid as a binder. The body has the following properties: apparent density 2.4 g/cm3; open porosity 23.8%; and the ultimate compressive strength 135.5 N/mm2. The developed body composition is recommended for preparing rammed lining of the ladles used for the vacuum treatment of steels.
