Abstract
A tuyere for torch guniting of a metallurgical plant comprises a water-cooled casing (1) inside which are mounted a pipeline (2) for feeding the gunite powder and a pipeline (3) for feeding oxygen into the cavity of the metallurgical plant with at least one guniting nozzle (4) mounted at the ends of said pipelines. The guniting nozzle (4) is provided with a channel (5) for feeding the gunite powder and a channel (6) for feeding the oxygen. The channel (6) for feeding the oxygen is located along the axis of the guniting nozzle (4), whereas the channel (5) for feeding the gunite powder encases the channel (6) for feeding the oxygen.
