Method for recycling desulfurization slag

摘要

Problem to be solved: to realize a method for recycling desulfurizing slag which can be applied even in the batch or continuous desulfurization process.Melting process of molten iron from cupolaDesulfurization process to remove sulfur from hot metal by desulfurization equipmentIn a steel making method havingA method for recycling desulfurized slag produced in the desulfurization processGrinding process for smelting slag desulfurization slagThe desulfurization slag is crushed in the grinding processThe classification process S2 classified by the sieve of 1 mm or lessAmong particles remaining on the sieve in classification processA magnetic sorting process S3 for selecting magnetic particles having magnetism andIncludingMagnetic particles sorted in the magnetic sorting process S3 are granulated.When the granulated magnetic particles are put into the cupola, the recycling process is performedAndIn the desulfurization process in which the magnetic particles are introduced into the desulfurization apparatus together with the hot metal, the reuse stepFurther includes at least one of.Diagram
