Abstract
Heat-treated products discharged from a discharge port of a movable hearth type heat treatment furnace, for example a rotary hearth type reduction furnace are discharged to a sorting means, the heat-treated products that foreign substances have been removed, are discharged through a seal leg into which anti-reoxidation gas is blown from a gas blowing nozzle, to a receiving recess of a receiving pan provided within a case having a hopper attached thereto which is a feeding means, and then a scraper is swung to discharge the heat-treated products deposited on the top surface of the receiving recess from the longitudinal ends of the receiving pan and simultaneously to quantitatively feed it to a molten iron-manufacturing furnace which is a downstream side facility, from the bottom side discharge port of the casing having a hopper attached thereto, and in addition, dust removal/cooling means for produced gas of the molten iron-manufacturing furnace and means for regulating the amount of produced gas are provided.
