MONOLITHIC REFRACTORY
PROBLEM TO BE SOLVED: To quickly develop the strength of a monolithic refractory without using alumina cement or by using an extremely low amount alumina cement and little CaO content and make same stronger.SOLUTION: There is provided a monolithic refractory having a content of CaSrAlO(0≤X≤0.5) of 0.5 mass% to 10 mass%, and content of polyvalent metal salt of oxycarbonic acid of 0.05 mass% to 1.0 mass% as a percentage based on 100 mass% of a refractory raw material having a particle diameter of 8 mm or less.SELECTED DRAWING: None
【課題】アルミナセメントを使用していない、あるいは、アルミナセメントの使用量が非常に少なく、ＣａＯ含有量が少ない不定形耐火物の強度発現を早くし、かつ、高強度にする。【解決手段】粒径８ｍｍ以下の耐火原料１００質量％に占める割合で、ＣａＸＳｒ１−ＸＡｌ２Ｏ４（但し、０≦Ｘ≦０．５）の含有量が０．５質量％以上１０質量％以下、オキシカルボン酸の多価金属塩の含有量が０．０５質量％以上１．０質量％以下である不定形耐火物。【選択図】なし
