VERFAHREN UND VORRICHTUNG ZUM EINLEITEN VON GASEN IN METALLSCHMELZEN |
摘要 |
Gases can be introduced in a finely divided form into molten metal using a jet-mixing facility which is designed on the Venturi principle and is made of a suitable refractory material. Melt flow rates of 2-100 m/s are measured in the cylindrical center piece of this mixer, and gas is sucked in at a reduced pressure of 0.05 to 0.9 bar. By means of this process an injector efficiency (ratio of throughput of propellant to throughput of purifying medium) of 3.75-4.0 is achieved. |
