Abstract

The invention relates to a lance (1) for introducing treatment substances into a melt. According to the invention, the lance (1) consists of a spacing means (3) being provided between an outer jacket pipe (4) and an inner inlet pipe (2). The spacing means has the shape of a generally tubular member making only point contact with the jacket pipe in outer contact points (11), and being connected thereto in at least some of the outer contact points (11). The invention also relates to a method for producing such a lance and a use thereof.
