Method of producing reduced iron and production facilities therefor.

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for producing a reduced iron pellet by which the reduced iron pellet hardly being crushed in a blast furnace because of high density and suitable as iron raw material for charging into the blast furnace cna be produced. SOLUTION: In this method, before cooling the high-temp. reduced iron pellet P2 heat-treated at high temp., the high-temp. reduced iron pellet P2 is rollingly moved in the temp. range of 800-1,200 deg.C. Therefor, this apparatus is provided with a heat insulation rolling part 22a for receiving the high-temp. reduced iron pellet P2 and rollingly moving the pellet P2 while holding the temp. between a rotary hearth type reducing furnace 21 and a rotary cylindrical cooler 22.
