    摘要： A method for sintering fine iron ore using a dual layer system is disclosed. Two layers of sintering charge are placed on a train of pallets and each of the layers is set on fire at given intervals of time to perform sintering of the charge. The upper layer of the charge is set on fire when the front flame point of the lower layer reaches grates of the pallet. The upper layer may contain, as a solid fuel, coal containing 10 wt% of higher of volatile matter.

    摘要： A method for manufacturing agglomerates of sintered pellets comprises the steps of mixing and pelletizing fine iron ore, flux, binder and return fines, coating pelletized materials, charging the green pellets into a sintering machine (13), drying charged green pellets in a drying furnace (14) and igniting the pellets in an ignition furnace (15), sintering the green pellets in the sintering machine, and measuring a noise level by the use of a noise sensor arranged on a sintering bed and controlling a sintering operation on the basis of the noise level.
    The noise level during igniting of the green pellets is measured by the use of a noise sensor (20) arranged on an ignition furnace and permeability of the green pellets are controlled on the basis of the noise level.
    The noise level is measured by the use of plurality of noise sensors (30a, 30b, 30c, 30d) arranged in the longitudinal direction of thesintering machine followed by the ignition furnace and the burn through point is controlled on the basis of the noise level.
    The noise level is measured by the use of plurality of noise sensors (40) arranged in the direction of a width of apallet following the ignitition furnace and densities of charged materials are controlled on the basis of the measured values.
