METHOD AND APPARATUS FOR PRODUCING SINTERED ORE

摘要

In production of sintered ore using an air suction type sintering process, a method and an apparatus for producing sintered ore by allowing sintering to progress under a state in which a magnetic levitation force is applied characterized in that the surface of a raw material layer is ignited, that after sintering has started at the upper layer portion of the raw material layer, a magnetic field is applied to the raw material by means of a magnetic levitation device that is not in contact with a sintered cake in which burning is completed so that a magnetic levitation force is applied thereto, and that while the magnetic levitation force is being applied, a magnetic levitation force acting in a widthwise direction which is normal to a sintered strand is distributed so that uniform sintering is achieved through uniform ventilation distribution. The method and apparatus are further characterized in that uniform sintering is achieved through continuous application of magnetic levitation force by means of a magnetic levitation device which can be moved while in contact with the sintered cake. The method and apparatus are still further characterized in that uniform sintering is achieved by applying magnetic levitation force mainly to portions of the sintered layer where ventilation is poor by means of a plurality of non-contact and movable magnetic levitation devices.
