First claim
Opening claim text (preview).
1 . A monolithic refractory, wherein, in terms of a proportion in 100 mass % of a refractory raw material haying a grain size of 8 mm or smaller, an amount of Ca X Sr 1−X Al 2 O 4 (where, 0≤X≤0.5) is 0.5 mass % or more and 10 mass % or less, and an amount of a polyvalent metal salt of oxycarboxylic acid is 0.05 mass % or more and 1.0 mass % or less. 2 . The monolithic refractory according to claim 1 , wherein an amount of the polyvalent metal salt of oxycarboxylic acid is 0.1 mass % or more and 1.0 mass % or less. 3 . The monolithic refractory according to claim 1 , wherein, in terms of a proportion in 100 mass % of a refractory raw material having a gain size of 8 mm or smaller, a total amount of Ca X Sr 1−X Al 2 O 4 (where, 0≤X≤0.5), Ca Y Sr 1−Y Al 4 O 7 (where, 0≤Y≤0.5) and 12(CaO) Z (SrO) 1−Z -7Al 2 O 3 (where, 0≤Z≤0.5) is 10 mass % or less. 4 . The monolithic refractory according to claim 1 , wherein, in terms of a proportion in 100 mass % of the refractory raw material, an amount of a magnesia raw material having a grain size of 0.1 mm or smaller is 3 mass % or more and 12 mass % or less. 5 . The monolithic refractory according to claim 1 , wherein, in terms of a proportion in 100 mass % of the refractory raw material, an amount of a spinel raw material having a grain size of 0.1 mm or smaller is 5 mass % or more and 25 mass % or less. 6 . The monolithic refractory according to claim 1 , wherein, in terms of a proportion in 100 mass % of the refractory raw material, a total amount of a spinel raw material or an alumina raw material, having a grain size of larger than 0.1 mm and 8 mm or smaller, or combination thereof is 55 mass % or more and 75 mass % or less.
