Filed: 1991-12-10
Abstract: PURPOSE:To obtain a castable refractory having improved slag infiltration resistance and thermal shock resistance to prolong the durable life by compounding a specific spinel raw material with magnesia, alumina and a binder. CONSTITUTION:The objective castable refractory is composed of 10-40wt.% of a spinel raw material, 5-20wt.% of magnesia and the remaining part of alumina and a binder. In the spinel raw material, electromelted spinel is used as the fraction having particle diameter of 0.05-2mm and the amount of the electromelted spinel is 5-25wt.% based on the total spinel raw material. The electromelted spinel particle has dense texture and low crystal grain boundary content and contains low-melting minerals such as SiO2 and CaO in the crystal grain boundary in isolated state and, accordingly, there is no instrusion of slag into the crystal grain boundary. When the particle size of magnesia exceeds 5mm, large cracks are generated at the circumference of the magnesia particle. The binder is alumina cement, etc.
