Development of self-flowing Al_2O_3-siC-C castable and its application to troughs of large blast furnaces

摘要

The developed self-flowing Al_2O_3-siC-Ccastable for troughs of blast furnace (BF) can self-flow under itsown gravity, leveling, degassing, compacting and setting withoutvibration by application of external energy. The self-flowingcastable with high strength, improved thermal shock resistance andgood resistance to molten slag and hot metal, has been used totroughs of large blast furnace, resulting in molten iron throughputof more than 100000 tons.
