Effect of alphabond300 additions on properties of Al^sub 2^O3-SiC-C castables

The use of refractory castables as a material for lining of runners of blast furnaces is considered. Ultra low cement and non cement castables are developed in conformance with modern technological requirements and environmental standards. The influence of alphabond300 additions on the performance of an ULC tab-corundum castables in the Al^sub 2^O3-SiC-C system was studied. The behaviors of various alphabond300 and CA270 cement additions in tab-corundum castables was evaluated in terms of flow value, apparent porosity, bulk density, mechanical properties, linear change rate, thermal shock resistance and oxidation resistance. Our study shows that the best performance in the Al^sub 2^O3-SiC-C systems is obtained using alphabond300 and the optimum content is considered to be 2 wt.%.[PUBLICATION ABSTRACT]
