GUNITE BURNER FOR TORCH-GUNITING OF METALLURGICAL PLANTS

摘要

A gunite burner comprises a casing (1) and a bushing (2) mounted coaxially to the casing (1) and provided with a threaded ring (3) mounted on its internal surface ''D'' with the possibility of axial movement. The external surface ''B'' of the casing (1) and the internal surface ''C'' of the threaded ring (3) have a conical configuration with a coning angle of 15 to 60 DEG and form a nozzle (4) for feeding the oxygen. The casing (1) is provided with a central nozzle (6) for feeding the gunite mass and with peripheral nozzles (7) for feeding the fuel which are located along a circumference coaxial to the central nozzle (6).
