REFORMING METHOD OF SLAG AND MANUFACTURING METHOD OF ROADBED MATERIAL
PROBLEM TO BE SOLVED: To provide a reforming method of slag which can suppress hydration expansion without steam aging treatment and oxygen blowing into molten slag.SOLUTION: The reforming method of slag includes dissolving an iron-containing raw material, a dry battery, and a slag containing CaO in an electric furnace and forming molten slag having the concentration of manganese oxide higher than 10 mass% on a surface of molten steel obtained by the dissolving process.SELECTED DRAWING: Figure 2
【課題】水蒸気エージング処理および溶融スラグへの酸素の吹き込みを行うことなく水和膨張を抑制できるスラグの改質方法を提供する。【解決手段】スラグの改質方法であって、鉄含有原料と、乾電池と、ＣａＯを含有する造滓剤とを電気炉で溶解し、溶解して得られた溶鋼の表面に形成される溶融スラグの酸化マンガン濃度を１０質量％より高くする。【選択図】図２
