APPARATUS FOR DIRECTLY MAKING LIQUID PIG-IRON FROM COARSE IRON ORE |
摘要 |
<p>A process and a device are described for directly making liquid pig-iron from coarse iron ore. Hot sponge-iron particles are directly conveyed by a worm conveyor (17) through a communicating passage (19) from a direct-reduction blast-furnace shaft (2) into a smelter-gasifier (1), and a stream (24) of gas flows, after cooling to below 950 DEG C., in counter-current to the sponge-iron particles, from the smelter-gasifier (1) to the blast-furnace shaft (2), this gas stream having a volumetric flow-rate not more than 30 percent of the total reduction-gas flow reaching the blast-furnace shaft (FIG. 1).</p> |
