High-Alumina Mixes Based on Molded Bauxite Suspensions

Resumo

Results of studying the rheotechnological properties of moldable refractory mixes based on bauxite suspensions plasticized with refractory clay are presented. Features of the effect of filler diameter and binder content in a mix on structural-mechanical and operating properties of specimens based upon it are established. Specimens from the developed mixes intended for molding at low pressure (up to 10 MPa) are characterized by high compressive strength (100 – 110 MPa) and relatively low porosity (up to 20 – 21%) after heat treatment at 1300°C.
