<p>An apparatus for reactor ironmaking has a furnace body (1A) to melt raw material, typically as scrap, a shaft (3) to heat the raw material, and a raw material supply bucket, (4) these three components being arranged vertically, with an exhaust gas combustion tower (5) positioned close to the shaft. …<??>Raw material is supplied to the shaft with this apparatus by the bucket, (4) and, after being heated by exhaust gas from the furnace body (1A), the raw material is charged into the furnace body (1A) by the opening/closing operation of a shaft damper (22) and a furnace body cover (21). Exhaust gas is introduced from the furnace body (1A) into the heating shaft (3), air is supplied in stages, the temperature of the gas is gradually raised through combustion of CO, and the gas is used to heat the raw material in the shaft.</p> |
