    • 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.
    • 目的:通过在炉渣中合并加入表面活性剂和亚硫酸盐,在高炉中加快缓慢冷却的炉渣老化。 构成:当将高炉中缓慢冷却的亚硫酸盐加入炉渣中时,炉渣中的CaS产生的游离S与SO3 <2->反应,因此不会产生多硫化物以防止产生黄色水。 当进一步加入表面活性剂时,通过表面活性剂的润湿和渗透作用,可以使用水溶胶。 contg。 溶解的亚硫酸盐渗透并快速渗透到炉渣中。 结果,由方程式表示的所述反应被有效地进行,少量的亚硫酸盐显示出显着的老化加速效果。 亚硫酸盐是亚硫酸钾,亚硫酸钠,亚硫酸铵等,并且阴离子,阳离子,两性和非离子表面活性剂中的任何一种可以用作表面活性剂。
