HEAT-INSULATING CASTABLE REFRACTORY
To provide a heat-insulating castable refractory that is less susceptible to cracking due to warpage cracking.SOLUTION: An heat-insulating castable refractory comprises, as refractory raw materials: CA6 aggregate having a grain size of 1 mm or more and consisting mainly of CaO_6Al2O3; silica fine powder having a grain size of less than 75 μm; and chamotte. In 100 mass% of the refractory raw materials, a content of the CA6 aggregate is 10 mass% or more and 60 mass% or less, a content of the silica fine powder is 5 mass% or more and 15 mass% or less, and a content of the chamotte is 10 mass% or more.SELECTED DRAWING: None
【課題】せり割れによる亀裂が発生しにくい断熱キャスタブル耐火物を提供する。【解決手段】耐火原料として、ＣａＯ・６Ａｌ２Ｏ３を主成分とする粒径１ｍｍ以上のＣＡ６骨材と、粒径７５μｍ未満のシリカ微粉と、シャモットと、を含む断熱キャスタブル耐火物であって、前記耐火原料１００質量％中に占める割合において、前記ＣＡ６骨材の含有率が１０質量％以上６０質量％以下、前記シリカ微粉の含有率が５質量％以上１５質量％以下、前記シャモットの含有率が１０質量％以上である、断熱キャスタブル耐火物。【選択図】なし
