ALUMINA-SILICA-BASED BRICK
PROBLEM TO BE SOLVED: To provide an alumina-silica-based brick having sufficient heat impact resistance as a lining refractory for an annular tube of a blast furnace or a hot blast main tube of a hot blast stove, especially a lining refractory for an aperture of the hot blast main tube of the hot blast stove, and excellent in creep resistance.SOLUTION: There is provided the alumina-silica-based brick which contains, as a sillimanite mineral in a mineral composition constituting a brick, 90 mass% or more in total of 20 mass% to 62 mass% of one or two or more kind of andalusite, kyanite and sillimanite, 20 mass% to 50 mass% of mullite, 3 mass% to 15 mass% of cristobalite and 29 mass% or less (including 0) of corundum and which has a gap between the sillimanite mineral and a matrix part.SELECTED DRAWING: Figure 1
【課題】高炉の環状管や熱風炉の熱風本管の内張り耐火物として、特に熱風炉の熱風本管開口部の内張り耐火物として十分な耐熱衝撃性を備え、しかも耐クリープ性にも優れたアルミナ−シリカ系れんがを提供する。【解決手段】れんがを構成する鉱物組成において、シリマナイト族鉱物としてアンダルサイト、カイアナイト、及びシリマナイトのうち１種又は２種以上を２０質量％以上６２質量％以下、ムライトを２０質量％以上５０質量％以下、クリストバライトを３質量％以上１５質量以下、並びにコランダムを２９質量％以下（０を含む）を合量で９０質量％以上含有し、シリマナイト族鉱物とマトリックス部との間に隙間を有しているアルミナ−シリカ系れんが。【選択図】図１
