The high-temperature strength increase solidification material of the iron stone dust, use that the pellet, and its production mannered

摘要

Cold strength is above equality to the former solidification material, at the same time, the high-temperature strength increase solidification material of the ore powder which is superior in revelation characteristic of high-temperature strength, uses for the pelletizing of the ore powder, the pellet, and its production method of using that are offered. Either the cement or the lime kind or combining two kinds and the slug, and the silicic acid quality substance, it becomes, chemical composition, CaO and Al₂ O while totaling₃, and SiO₂, CaO 3 - 56%, Al₂ O₃ 3 - 40%, and SiO₂ is 30 - 86%, the high-temperature strength increase solidification material of the ore powder, either the cement or the lime kind or two kinds, combination ratio of the slug, and the silicic acid quality substance, either the cement or the lime kind or two kind 1 - 76 sections, the slug 2 - 95 sections, and silicic acidThe said solidification material which is the quality physical 2 - 95 sections, furthermore, containing the gypsum, the said solidification material which becomes, the ore powder, containing the said solidification material, and the water, the pellet and the said solidification material which become, are the said pellet which is 3 - 20 sections vis-a-vis the ore powder 100 section, the water/(the ore powder + said solidification material) ratio 0.03 - 0.3 constitutes the production method of the said pellet, and the said pellet which are.
