Development of Self—flowing Al2O3—SiC—C Castable and Its Application to Troughs of Large Blast Furnaces

摘要

The developed self-flowing Al2O3-SiC-C castable for troughs of blast furnace(BF) can self-flow under its own gravity,leveling,degassing,compacting and setting without vibration by aplication of external energy,The self-flwoing castable with high strength,improved thermal shock resistance and good resistance to molten slag and hot metal,has been used to troughs of large blast furnace,resulting in molten iron throughput of more than 100000 tons.
