摘要： PURPOSE: To provide a composition for improving reduction degradation index in a blast furnace by water treating manufactured sintered ore, thereby closing pores existing in sintered ore and coating precipitates on the surface of sintered ore, a method for preparing the composition, and a water treating method of sintered ore by reduction degradation improvement of sintered ore using the composition. CONSTITUTION: The composition for preventing reduction degradation of sintered ore comprises 10 to 35 weight parts of calcium chloride and 0.05 to 3 weight part of lithium contained compound, wherein the composition further comprises 0.05 to 0.7 weight part of boron contained compound, and a compound comprising one or more components selected from the group consisting of magnesium, silicon, titanium and iron. The method for preparing the composition comprises a step of obtaining a reaction mixture by adding a lithium contained compound to the solution and reacting the lithium contained compound with the solution after dissolving calcium chloride into water; and a step of adjusting pH of the reaction mixture. The water treating method of sintered ore by reduction degradation improvement of sintered ore comprises a step of preparing an aqueous solution by dissolving the composition into water; a step of manufacturing sintered ore of which surface and pores are coated with the composition by spraying the aqueous solution onto sintered ore before charging sintered ore into a blast furnace; a step of removing moisture in grains of sintered ore by drying the composition coated sintered ore; and a step of charging the dried sintered ore into the blast furnace.
