METHOD AND APPARATUS FOR TRANSFERRING HEAT TO MOLTEN METAL |
| 摘要 |
<p>A method and an apparatus, wherein heat can be effectively transferred to molten metal contained in a reaction vessel. The pressure of the gaseous atmosphere within the vessel is maintained higher than atmospheric pressure. Oxygen gas is blown to a layer of molten slag contained in the vessel through tuyeres set in the reaction vessel, thereby to achieve post-combustion therein. The pressure in the vessel is controlled within the range of 2.0 to 5.0 kg/cm2 by a pressure regulator.</p> |
