Abstract
When casting castable refractories as lining refractories of a ladle for a molten metal, wherein the castable refractories are prepared by kneading monolithic refractories with an aqueous solution of a binder containing alumina cement, the castable refractories are preheated on the basis of the open air temperature and cured after casting while keeping the temperature thereof within a set temperature range of from about 20.degree. C. to 40.degree. C. The method stabilizes the hardening time of castable refractories and forms cast refractories excellent in strength and erosion resistance.
