Embodiment Construction
[0038] exist figure 1 In , 1 represents a part of the molten metal pool, such as the molten aluminum alloy pool. The immersion pipe system shown in this example with a jacket 3 extends into the bath. The air supply pipe 4 is concentric with the casing inside the casing. The bushing 3 and the gas supply pipe 4 are connected to each other by an O-ring 5 which also provides a seal against gas leakage.
[0039] As a result of the submersion of a part of the casing 3 into the molten pool 1, a convex meniscus is formed inside the casing. Preferably at least a portion of the inner wall of the sleeve is made of a non-wetting material. A laser beam 15 generated by a laser source (not shown) meets the meniscus at the location of the meeting surface 7 above the focal point of the laser beam to prevent positioning problems and to prevent the gas above the meniscus from forming a plasma.
[0040] The channel 8 of the air supply pipe 4 has a central narrowing 9 .
[0041] The direction...
