Abstract
A method and a particle absorber for separating off entrained particles from a stream of molten metal are proposed. The particle absorber has a multiplicity of surfaces within the metal stream produced by means of mechanical separation. This separation leads to a change in the velocity of the flowing metal and to a change in the surface tension. The entrained non-metallic particles are pushed out of the metal stream into the surface regions and blocked there on the separation surfaces. The proposed method and the particle absorber show a good separation effect and, furthermore, are an inexpensive alternative to conventional systems.
