Abstract
The present invention relates to an apparatus for manufacturing molten irons and a method for manufacturing molten iron using the same. The method for manufacturing molten irons according to the preseThe present invention relates to an apparatus for manufacturing molten irons and a method for manufacturing molten iron using the same. The method for manufacturing molten irons according to the present invention includes reducing first iron ores by charging the first iron ores into a fluidized-bed reduction reactor; manufacturing compacted irons by compacting the reduced first iron ores; reducingnt invention includes reducing first iron ores by charging the first iron ores into a fluidized-bed reduction reactor; manufacturing compacted irons by compacting the reduced first iron ores; reducing second iron ores together with the compacted irons by charging the second iron ores and the compacted irons into a packed-bed reduction reactor, a size of the second iron ores is greater than a sizesecond iron ores together with the compacted irons by charging the second iron ores and the compacted irons into a packed-bed reduction reactor, a size of the second iron ores is greater than a sizeof the first iron ores; charging the reduced compacted irons and the second iron ores into a melter-gasifier connected to the packed-bed reduction reactor; preparing lumped carbonaceous materials as aof the first iron ores; charging the reduced compacted irons and the second iron ores into a melter-gasifier connected to the packed-bed reduction reactor; preparing lumped carbonaceous materials as aheating source for melting the reduced compacted irons and the second iron ores; charging the lumped carbonaceous materials into the melter- gasifier and then forming a coal packed-bed; and injecting heating source for melting the reduced compacted irons and the second iron ores; charging the lumped carbonaceous materials into the melter- gasifier and then forming a coal packed-bed; and injectingoxygen through a tuyere installed in the melter-gasifier and then manufacturing molten iron from the compacted irons and the second iron ores. oxygen through a tuyere installed in the melter-gasifier and then manufacturing molten iron from the compacted irons and the second iron ores.
Description
technical field [0001] The present invention relates to an apparatus for manufacturing molten iron and a method for manufacturing molten iron using the apparatus. More particularly, the present invention relates to an apparatus for manufacturing molten iron and a method for manufacturing molten iron using the apparatus to reduce fine iron ore having a wide range of particle sizes. Background technique [0002] The steel industry is a core industry that provides the basic materials needed in the construction industry as well as in the manufacture of automobiles, ships, household appliances and many other products we use. It is also one of the industries with the longest history accompanying human development. Iron foundries play an important role in the steel industry where steel is produced from molten iron after producing molten iron (which is pig iron in a molten state) by using iron ore and coal as raw materials and then supplied to consumption By. [0003] Currently, ...
