Abstract
A tuyere for torch gunite comprises a water-cooled casing consisting of two pipes (1 and 2). Inside the water-cooled casing are mounted coaxially pipes (4) for supplying a powder like mixture of refractory material and a fuel and pipes (3) for supplying the oxigen. At the outlet ends of the said pipes (3 and 4) along their walls are mounted nozzles (5) for supplying the powder-like mixture of the refractory material and the fuel and nozzles (6) for supplying the oxygen, all combined in pairs and located coaxially in each pair. The face of each nozzle (5) for supplying the powder-like mixture of the refractory material and the fuel is placed below the face of each corresponding nozzle (6) for supplying the oxygen at a distance equal to 1 to 5 internal diameters of the nozzle (5) for supplying the powder-like mixture of the refractory material and the fuel. The walls of at least one nozzle (5 or 6) of each pair have, fully or partially, a form different from that of a cylinder.
