Zusammenfassung:PURPOSE: A sintering truck with a high air permeability is provided which improves productivity and recovery ratio by increasing air permeability of the lower part of a bed of the sintering truck during manufacturing of sintered ore in which fine iron ore used as a principal raw material is manufactured into sintered ore in a blast furnace. CONSTITUTION: In a sintering truck(100) having a grate bar(10) on which vents are formed so as to enable ventilation during sintering operation of blended materials charged and which is installed at the lower part of a bed, the sintering truck with a high air permeability comprises vents(30) a plurality of which are installed at the body(10a) of the grate bar(10) in a length direction, and at the center of the inner part of which vent holes(32) additionally enabling ventilation of the blended raw materials are formed, wherein the vents(30) further comprises screw parts(34) connected to screw grooves(10b) a plurality of which are formed in a length direction of the grate bar(10), and triangular pyramid shaped protrusion parts(36) which are integrally formed at the upper side of the screw parts(34), and wherein the vent holes(32) are integrally penetrated into the center of the inner parts of the protrusion parts(36) and the screw parts(34), and lower and upper parts of which have different diameters so that the vent holes(32) are formed in a cone shape. 본 발명은 통기성을 높인 소결대차에 관한 것으로 그 목적은, 소결대차의 하부에 적층되는 상부광의 사용량을 상당히 절감시키면서도 소결대차의 통기성은 향상시키도록 하는 한편, 균일한 동기작용이 이루어 져 소결광의 품질을 향상시킴으로서 이를 이용한 고로작업의 생산성을 향상시키는 도록 하는 데에 있다. 따라서, 상기와 같은 목적을 달성하기 위하여 본 발명은, 장입된 배합원료의 소결작업시 통기를 가능토록 협력하여 통기구를 형성키고 소결대차의 베드 하부에 설치되는 그레이트 바아(10)의 몸체(10a) 길이방향으로 다수개 설치되며, 내부 중앙에는 배합원료(10)의 통기를 추가적으로 가능토록 하는 통기공(32)이 형성되는 통기구(30)를 구비하는 통기성을 높이 소결대차를 제공한다.
