A case, in which an inner bottom surface is formed, and a chuck tool in which a lower surface is formed are provided. The inner bottom surface is a concave surface. The lower surface is a concave surface. An elongated member chucking apparatus changes an orientation of an elongated member inside the case to a predetermined orientation with respect to the chuck tool by sandwiching the elongated member between the inner bottom surface and the lower surface. The elongated member is held by the chuck tool in the predetermined orientation.

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.

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.
