摘要
A method and a product is provided for reducing the reduction disintegration of iron ores and iron ore agglomerates. The raw iron ores or iron ore agglomerates are treated with materials containing halogen and preferably with halogenide solutions. The degree of the improvement of reducing disintegration in a reduction furnace such as a blast or low shaft furnace at temperatures from about 400 to 600 degrees centigrade depends on the concentration employed. The type of reagent has its particular effect, because the reagents contain stochiometrically different high proportions of halogens. It is found that reduction disintegration declines with the increased halogenide concentration in the pieces of ores or agglomerates employed. In order to minimize the amount of extraneous materials introduced, the lowest possible concentration is advantageously determined for each burden component.
