Abstract
Investigations were carded out with differeut types of bauxitesj and chromites to prep;are chrome-alumina refractories. Raw ma~erials mixed in suitable proportions to give 10-12 percent Cr20 3 in the product were calcined at 1600° and then graded. Bricks formed under pressur.e and fired to 1600° indicate promising results but high porosity. Lime addition (2-3%) in ~he mixes appreciably reduces porosity but slightly affects the refractoriness. Chrome orej containing about 5 percent silica is suitable for the purpose. Chrome-alumina refractories thus made possess desirable properties and their use in steel pourzing ladles and regenerators of open hearth furnaces may be considered.
