A method, an installation and a nozzle (1) for suppressing the generation of iron-containing vapor during filling or emptying of a container (2) for an iron-containing metal melt with the aid of CO2 snow, a CO2 snow jet (22) being applied by means of the nozzle (1) dispersing in a substantially planar manner onto a surface of an iron-containing stream (23) which is poured into or out of the container (2). The invention consequently at least partially solves the technical problems outlined in connection with the prior art. In particular, a device is proposed which allows cost-effective and space-saving suppression of the generation of iron-containing vapor during the filling or emptying of a container 2 with the aid of a reduced CO2 snow quantity.
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 CO2 snow, characterized in that a CO2 snow jet is applied by means of a nozzle dispersing the CO2 jet in a substantially planar manner onto a surface of an iron-containing stream which is poured into or out of the container, wherein:
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 CO2 snow characterized in that a CO2 snow jet is applied by means of a nozzle dispersing 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 is positioned at a distance to the container of at least 1 meter with a moveable, mechanical guide arm.
Installation for carrying out a method of 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 CO2 snow in which a CO2 snow jet is applied by means of a nozzle dispersing the CO2 jet in a substantially planar manner onto a surface of an iron-containing stream which is poured into or out of the container, said method comprising a container for an iron-containing metal melt, a control unit, a moveable, mechanical guide arm, and a nozzle mounted to the arm and spaced apart from the container for producing a substantially planar CO2 snow jet or suppressing the generation of iron-containing vapor during the filling or emptying of a container for an iron-containing metal melt, wherein:
