摘要
A process for the direct reduction of iron ore uses a shaft furnaces through which the ore passes downwards by gravity. The furnace is charged continuously in its upper part with a mixture of solid fuel and iron ore, and finely distributed oxygen is blown into its central part at low velocity. Gases released at the upper part are recirculated to the lower part.
