Abstract:
1. A method for suppressing the generation of iron-containing vapor during filling or emptying of a container for an iron-containing metal melt with the aid of CO 2 snow, characterized in that a CO 2 snow jet is applied by means of a nozzle dispersing the CO 2 jet in a substantially planar manner onto a surface of an iron-containing stream which is poured into or out of the container, wherein: the nozzle has an outlet axis, a vertical axis, a transverse axis, an inlet and an outlet; the inlet and outlet are are spaced apart by a distance along the outlet axis; the outlet axis is perpendicular to the vertical axis and the transverse axis; and the nozzle tapers along the vertical axis toward the outlet to an outlet height and widens along the transverse axis toward the outlet to an outlet width.
