    Abstract: PROBLEM TO BE SOLVED: To provide an anticaking agent for iron and steel slag represented by granulated blast furnace slag, and capable of expressing excellent anticaking effect for a long period of time. SOLUTION: The anticaking agent for iron and steel slag includes (A) at least one member selected from the group consisting of phosphonic acid derivatives and salts thereof and (B) at least one member selected from the group consisting of aliphatic hydroxycarboxylic acid derivatives and salts thereof. In the anticaking agent, a mixing ratio (A)/(B) in mass ratio is expressed by (A)/(B)=95/5-5/95, wherein (A) and (B) are described above. High synergistic effect on anticaking ability may be expressed by comprising (C) a sugar alcohol in addition. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract: PURPOSE:To accelerate the aging of slag cooled slowly in a blast furnace by combinedly adding a surfactant and sulfite to the slag. CONSTITUTION:When sulfite is added to slag cooled slowly in a blast furnace, free S produced from CaS in the slag reacts with SO3 in accordance with the equation, so no polysulfide is produced to prevent the production of yellow water. When a surfactant is further added, by the wetting and penetrating actions of the surfactant, an aqueous soln. contg. dissolved sulfite penetrates and disperses rapidly into the slag all over. As a result, said reaction represented by the equation is efficiently carried out, and a little sulfite shows a significant aging accelerating effect. The sulfite is potassium sulfite, sodium sulfite, ammonium sulfite or the like, and any of anionic, cationic, amphoteric and nonionic surfactants may be used as the surfactant.
