摘要： An apparatus for producing reduced iron, and a compact drying method for application to the apparatus are disclosed. The apparatus comprises a pelletizer or a briquetter for mixing and agglomerating coal as a reducing agent and iron ore as iron oxide to form compacts, a dryer for drying the compacts, a circular rotary hearth type reducing furnace for reducing the dried compacts in a high temperature atmosphere, a first heat exchanger for performing heat exchange between a hot off-gas discharged from the reducing furnace and combustion air to be supplied to the reducing furnace, and coolers for cooling the hot off-gas. A second heat exchanger for heating drying air is disposed on an exit side of the first heat exchanger. The drying air heated by the second heat exchanger is supplied to the dryer to dry the compacts with the drying air which is scant in moisture. Consequently, highly efficient, stable drying in the dryer can be performed, and high quality reduced iron can be produced stably.

摘要： A pretreatment apparatus for raw materials for production of reduced iron pretreats the raw materials, comprising an iron material, such as iron ore, and other raw materials, such as coal and flux, by a dryer, classifiers, a roll press, and a vertical mill, and feeds the pretreated raw materials to a pelletizer via a feed bin. At least two fluidized mixers for mixing the classified raw materials, one of the fluidized mixers for storage and the other fluidized mixer for supply, are provided for batch treatment. The pretreatment apparatus can uniformize the crushed particle sizes of iron ore, coal, etc. different in hardness, stably supply homogeneously mixed raw materials, and simplify pelletization-side facilities.

摘要： A reduced iron discharger in a rotary hearth reducing furnace scoops up reduced iron on a rotary hearth from a front side with the use of an impeller enough long to cover the entire width of the rotary hearth, drops the reduced iron onto a vibrating conveyor mounted in the impeller, and discharges it from an outlet to the outside of the reducing furnace. The reduced iron discharger involves minimal structural waste, and gives a satisfactory yield.

摘要： An evaporation source having a nozzle structure that makes the distribution of film thickness uniform in the width direction of a substrate and a vacuum evaporator using the same are provided. A vapor produced by evaporation or sublimation by heating to evaporation material is discharged from a long nozzle opening like a band. A deposited substrate is transferred in a direction perpendicular to the longitudinal direction of the nozzle opening while facing the nozzle opening. A discharge flow rate of vapor per unit area in the longitudinal direction of the nozzle opening is made to be maximum in a portion at a nozzle width direction position corresponding to a substrate edge position rather than a central part of the nozzle opening and a plurality of partition plates providing directivity to the flow of vapor are arranged inside the nozzle opening.
