METHOD FOR MANUFACTURING GRANULAR SINTERED RAW MATERIAL

Proposed is a novel method for manufacturing a granular sintered raw material wherein steam is used during granulation to manufacture a heated granular sintered raw material, which is effective in improving permeability and enables improvement in the productivity of sintered ore in cases where this granular sintered raw material is introduced into a sintering machine. In the proposed method for manufacturing a granular sintered raw material, when a sintered blended raw material, in which a carbon material and/or an auxiliary material in addition to iron ore powder are blended, is granulated ina granulating machine, water vapor is blown into the granulating machine, thereby producing a granular sintered raw material having a temperature of at least 10 DEG C higher than the temperature of the sintered blended raw material prior to being loaded into the granulating machine. 本发明提出一种新的造粒烧结原料的制造方法，该方法通过制造在造粒时使用蒸气加热而成的造粒烧结原料，从而在将其装入烧结机时，能够有助于透气性的改善，并且提高烧结矿的生产性。该造粒烧结原料的制造方法包括：在利用造粒机对除铁矿石粉以外还配合炭材料、副原料而成的烧结配合原料进行造粒时，向该
