ALUMINA-SILICON CARBIDE-CARBONACEOUS BRICK
PROBLEM TO BE SOLVED: To provide a new alumina-silicon carbide-carbonaceous brick high in durability.SOLUTION: A binder is added to a refractory raw material blend comprising: graphite in which the content of intermediate grain alumina with a grain size of 0.075 to below 1 mm is 35 to 55 mass%; coase grain alumina with a grain size of 1 to below 5 mm by 0.25 to 1.00 in a mass ratio to the intermediate grain alumina;fine grain alumina with a grain size below 0.075 mm by 0.05 to 0.30 in a mass ratio to the intermediate grain alumina; graphite in which the ratio of the intermediate grains with a grain size of 0.075 to below 1.0 mm is 50 mass% or higher by 3 to 20 mass%; silicon carbide in which the ratio of fine grains with a grain size below 0.075 mm is 50 mass% or higher by 1 to 10 mass%; a metal in which the ratio of fine grains with a grain size below 0.075 mm is 70 mass% or higher by 0.1 to 5 mass%, and in which the total content of the alumina is 60 to 95 mass%, to perform kneading, molding and heat treatment.
【課題】これまでになかった耐用性の高いアルミナ−炭化珪素−炭素質れんがを提供すること。【解決手段】粒径０．０７５ｍｍ以上１ｍｍ未満の中間粒のアルミナを３５質量％以上５５質量％以下、粒径１ｍｍ以上５ｍｍ未満の粗粒のアルミナを前記中間粒のアルミナに対して質量比で０．２５以上１．００以下、粒径０．０７５ｍｍ未満の微粒のアルミナを前記中間粒のアルミナに対して質量比で０．０５以上０．３０以下、粒径０．０７５ｍｍ以上１．０ｍｍ未満の中間粒が５０質量％以上である黒鉛を３質量％以上２０質量％以下、粒径０．０７５ｍｍ未満の微粒が５０質量％以上である炭化珪素を１質量％以上１０質量％以下、粒径０．０７５ｍｍ未満の微粒が７０質量％以上である金属を０．１質量％以上５質量％以下含有し、かつ、アルミナの合量が６０質量％以上９５質量％以下である耐火原料配合物にバインダーを添加して混練、成形、熱処理する。【選択図】なし
