PROCEDIMENTO E DISPOSITIVO PER IMPEDIRE IL CONTATTO DI OSSIGENO CON UNA MASSA METALLICA FUSA. |
摘要 |
<p>Method of preventing contact of oxygen with a metal melt during continuous casting, the metal melt flows into a casting chamber bounded by rolls and a hood and leaves this chamber as a stream. To completely prevent contact of oxygen with the metal melt and thus reoxidation, oxygen attempting to enter via any gaps between the walls and/or adhering to the walls is removed by suction applied at a succession of suction stages at the periphery of each roll before a gap between the hood and the roll at the top of the casting chamber. Inert gas may then flow to the rolls near the gap.</p> |
