Abstract (en)

[origin: EP0947587A1] The invention relates to a method for cooling a lance provided for converting a medium into a molten mass and/or for measuring the properties of the molten mass. A gas/liquid mixture is fed as a cooling medium into a cooling circuit which is closed up to the lance end (2) situated on the melting side. The invention provides that the gas/liquid mixture or the components thereof is/are fed and permitted to expand under pressure up to the area of the lance end (2) situated on the melting side. The invention also relates to a lance which has a mixing chamber (5, 6) connected to the cooling circuit. The mixing chamber has the connections (3, 7) for a gas and liquid supply which is designed to produce the gas/liquid mixture, whereby the mixing chamber (5, 6) is connected via a pressure line (10) to at least one two-component nozzle (11) arranged in the area of the lance end (2) which is situated on the melting side.
