ABSTRACT:
The process includes the delivery of molten metal for solidification in stepped flow and the blowing of a gas through the flow at a step located at the level of the surface of that portion of the flow which is directly fed for solidification, or at a level exceeding said level by as much as 300 mm.
The apparatus for realizing said process comprises a tundish with a stepped bottom. A means for blowing the gas through the flow of metal is provided within that portion of the tundish which is located level with the upper generatrix of the outlet from the tundish or preferably, at a level about 300 mm above said generatrix.
