REFRACTORY COMPOSITION FOR TAP HOLE IN MELTER-GASIFIER OF FINEX

摘要

A refractory composition for a tap hole in a melter-gasifier of finex is provided to show an excellent thermal shock resistance and an excellent wear resistance, and improve a lifespan of the tap hole in a melter-gasifier of finex. A refractory composition for a tap hole in a melter-gasifier of finex is used in a tap hole of a melter-gasifier during a finex process. The refractory composition includes Al2O3, carbon, and inevitable impurities. A content of the Al2O3 is 19-59wt%, a content of the carbon is 40-80wt%, and a content of the inevitable impurities is 1-10wt%. The inevitable impurities are selected from the group consisting of CaO, MgO, and combinations thereof.
