SPRAY REFRACTORY COMPOSITION AND PRODUCTION METHOD THEREOF
To provide a spray refractory composition which has high adhesiveness, little rebound loss, reduced sorting time and cost, and comprising a used product which readily available.SOLUTION: A spray refractory composition mainly comprises magnesia spinel brick waste and a magnesia raw material as refractory raw materials. The content of the magnesia spinel brick waste is 10 mass% or more based on 100 mass% of the refractory raw materials, and the content of the magnesia raw material is 0 mass% or more and 90 mass% or less based on 100 mass% of the refractory raw materials.SELECTED DRAWING: None
【課題】 接着性が高く、リバウンドロスが少なく、さらに、選別時間とコストが低減され、調達が容易な使用後品を配合した吹付耐火組成物を提供すること。【解決手段】 吹付耐火組成物は、耐火原料として主にマグネシア・スピネルれんが屑と、マグネシア原料を含み、マグネシア・スピネルれんが屑の含有量が耐火原料１００質量％に対し１０質量％以上であり、マグネシア原料の含有量が耐火原料１００質量％に対し０質量％以上９０質量％以下である。【選択図】 なし
