PURPOSE: A sintered ore structure and a sintered ore manufacturing method are provided to improve the combustion speed and efficiency of sintered ore because cokes and anthracite coal of large grain size are arranged in outer side of the sintered ore structure. CONSTITUTION: A sintered ore manufacturing method is as follows. Cokes and anthracite coal are sorted, according to grain size, into small grains and large grains(S1). The sorted small grains of cokes and anthracite coal are put into a mixer together with iron ore and supplementary raw material(S2). Moisture is supplied to the inside of the mixer(S3). The large grains of cokes and anthracite coal are put into the mixer and mixed to be coarse particulates(S4). |
