CARBON-CONTAINING REFRACTORY

摘要

PURPOSE:To obtain carbon-contg. refractories having satisfactory spalling and corrosion resistances and effective as the material of each fireproof member of a continuous casting machine by making use of an alumina-silicon carbide composite material having a low coefft. of thermal expansion and excellent in corrosion resistance. CONSTITUTION:In carbon-contg. refractories contg. 5-40wt.% carbonaceous stock, 2-95wt.% alumina-silicon carbide composite material is contained as an essential component. The molar ratio between Al2O3 and SiC in the composite material is 50:1 to 1:5.
