<p>This invention provides a process for producing a sintered ore by feeding various gas fuels from the upper part of a charge layer of a sintering material deposited on a pallet in a sintering machine. In the process for producing a sintered ore, a gas fuel diluted to a lean flammability limit concentration or less is used as the gas fuel fed from the upper part of the charge layer on the pallet, and, in feeding the gas fuel for sintering, at least one of the feed position, charge layer highest attainable temperature, or holding time in a high temperature range is regulated to produce a sintered ore. There is also provided a sintering machine characterized by comprising a gas fuel feed apparatus.</p> |
