Abstract (en)
[origin: WO2014023372A1] The invention relates to a hot-blast lance for use in metallurgical processes, such as for example steel production, with which hot air can be blown in above a molten bath of a steel converter, which consists of an outer shell and at least one inner shell, and at least one intermediate space or cooling channel through which coolant flows is arranged between the outer shell and an inner shell. In order to achieve the effect here that a hot-blast lance can be further developed to the extent that hot air can be introduced into a reaction vessel, for example a steel converter, particularly effectively, that is to say with least possible thermal losses, and the lance is adapted better to this operating environment, it is proposed according to the invention that the inner shell (2) or the innermost shell (4) at least partially consists of a thermally insulating further shell (4), or a thermally insulating shell, or is provided with such a shell, or is coated with a thermally insulating layer.
