Abstract
A tuyere for torch guniting of a metallurgical plant lined with a refractory material comprises a cooled casing inside which pipelines (3, 4) for supplying oxygen and the gunite mass into the cavity of the plant. The tuyere further comprises at least one slot-shaped nozzle (5) intended for supplying the gunite mass to the lining area to be restored, connected to the pipeline (4) for supplying the gunite mass and located on the side wall of the tuyere, near its end-face, parallel to the axes of the pipelines (1, 2, 3, 4). The tuyere is also provided with nozzles (6) for supplying the oxygen to the lining area to be restored which are connected to the pipeline (3) for supplying the oxygen and are spaced evenly along the longer sides of each slot-shaped nozzle (5) for supplying the gunite mass.

Due to the large surface area of the shuya-parallels of the mixture of the mixture of oxygen and the particle, the absorption of the solution is ameliorated, which results in an increase in the dissipation of the room. The incidence of corpuscular particles is increased by a factor of 10 when the increase in consumption is slower, and there is an increase in With the help of such a site, the efficiency of applying a spread mass of up to 70 is achieved.

If the gap is too large. a wide, well-defined path of the mass at the site. The rates are much higher than at the beginning of the battle. If the gap is too large, then it’s most likely that the load will increase at the beginning of the burst if it rises from the load. In this case, there may be a place for clogging of the slit-like sorbent with the mass of the c. As a result, the aggregate of the unit will be washed out by the kyrielod stream and keep it lowered. -
