FIELD: power engineering.SUBSTANCE: invention relates to the method for production of oxide-fuel briquettes, which includes preparation of a mixture for briquetting with the following composition, wt %: coal breeze - 45-64, blast furnace dust, iron scale - 25-50, lime - 5-6, a derivative of sulphonic acid or mollasses - 5-6, compaction of the mixture in vibromoulds and drying of briquettes, differs by the fact that at the stage of mixture preparation for briquetting, the following components are added to it, wt %: table salt - 20-30, and after drying of the produced briquettes they are placed into water for dissolving salt, and the drying process is repeated.EFFECT: method makes it possible to increase strength, heat resistance and porosity of briquettes, increasing their reactivity and efficiency of iron oxides recovery, and may be used in metallurgical and machine-building industries.1 cl |
