METHOD AND APPARATUS FOR ADDING SOLID ALLOYING INGREDIENTS TO MOLTEN METAL STREAM |
摘要 |
<p>An elongated, vertical conduit has an upper end, communicating with the bottom opening in an upper container or ladle, and an open lower end disposed above the top surface of a bath of molten metal in a lower container or tundish. A descending stream of molten metal is directed from the conduit into the bath. A shroud encloses the conduit and the descending stream. The pressure within the shroud is lower than the outside pressure and is regulated. A mixture of transport gas and solid, particulate alloying ingredient prone to excessive fuming is injected into the descending stream within the shroud.</p> |
