CASTING MONOLITHIC REFRACTORY
PROBLEM TO BE SOLVED: To provide a method for suppressing shrinkage cracks after curing and improving the strength after firing at 1000°C in casting monolithic refractories without addition of alumina cement by using aluminum lactate.SOLUTION: In the method for producing casting monolithic refractories, an organic fiber is added in an amount of 0.05 to 0.3 mass% in outer percentage as a curing inhibiting material to a formulation in which aluminum lactate is added in an amount of 0.1-2.0 mass% in outer percentage with respect to 100 mass% of refractory material. Further, ultrafine alumina powder having a specific surface area of 50 to 150 m2/g is added by 1.0-10.0 mass% in outer percentage to improve the strength after firing at 1000°C.SELECTED DRAWING: None
【課題】アルミナセメント無添加の流し込み不定形耐火物において、乳酸アルミニウムを用いて硬化させ、養生後の収縮亀裂抑制及び、１０００℃焼成後強度の向上を行なう方法の提供。【解決手段】耐火材料１００質量％に対し、乳酸アルミニウム０．１〜２．０質量％を外掛けで添加した配合に、養生亀裂抑制材として有機繊維を外掛けで０．０５〜０．３質量％添加し、１０００℃焼成後強度の向上のために、比表面積50〜150m2/gのアルミナ超微粉１．０〜１０．０質量％を外掛けで添加する流し込み不定形耐火物の製造方法。【選択図】なし
