A SIC BASED ALUMINOUS DRY CASTABLE FOR LINING BLAST FURNACE THROUGH/ RUNNERS AND A PROCESS FOR PRODUCING THE SAME

摘要

A SiC based aluminous dry- castable composition for lining blast furnace troughs/runners, which castable possesses an extended performance life, is easily de-skullable and does not produce any fumes during its application to the troughs/runners of a blast furnace cast house, characterized in that the said castable is of the optimum composition by weight % : AI2O3-7I to 82, Fe2O3-0.6 to 1.0,SiO2-5to 10 SiC-11 to 15,Ca0-0.7to 1.2-andC-l to 2.
