Title:
METAL ORE REDUCTION METHOD AND APPARATUS
Document Type and Number:
Japanese Patent JPS57155309
Kind Code:
A
Abstract:
A method and apparatus is disclosed for reducing metal ore to sponge metal in a vertical shaft, moving bed, gaseous reduction reactor by controlling the amount of gas intermixing between the reduction and cooling zones of the reactor to result in increased productivity and improved carburization of sponge iron. In accordance with a preferred embodiment, process efficiency is maximized while capital cost is minimized through the use of an optimally designed reactor with a pre-determined equivalent height to equivalent diameter ratio.
