At present, with the large-scale environmental protection transformation of the metallurgical industry, the use and development of refractory gunning materials in steel mills and production enterprises are also getting faster and faster. Traditional spraying methods are used in repairing furnaces such as smelting ladles, converters, and electric furnace blast furnaces. Although it is used in basic engineering, refractory gunite machine also has very high requirements in high-standard steelmaking technology projects.
The refractory gunite machine for maintenance of heater and boiler developed by our factory has been promoted and applied in domestic steelmaking enterprises, and has been unanimously recognized by the units that use it. At present, hundreds of domestic iron and steel enterprises have successfully put it into use.
Refractory gunite machine for maintenance of heater and boiler uses compressed air to transport refractory materials or similar loose materials through pipelines, control adding water and mixing them at the port, and then spray them on the sprayed surface at high speed to condense and harden, thereby forming a material protection layer with a certain strength.
For refractory spray guns, there is ABB frequency conversion for regulating the output. A small output will help avoid blocking in use when the machine starts working. The refractory gunite machine is equipped with a new pre-wet nozzle. Compared with ordinary nozzles, it has the following advantages:
1). Low rebound, low dust;
2). Reduce the amount of water added.
3). Improve the compactness and strength of refractory materials.
Put the refractory materials into the vibrating hopper, pass through the screen and enter the straight-through material cavity of the rotor, and rotate with the rotor to the discharge port, where the compressed air from the upper air path enters the cyclone, and then is introduced into another cyclone by the cyclone A stream of compressed air blows away, accelerates, rotates and floats the material in a multi-head spiral state, enters the delivery pipe, and mixes with water to spray the sprayed surface when it reaches the nozzle.
Refractory gunite machine is also suitable for indoor and outdoor wall spraying, cement mortar grouting, bridge grouting and waterproof surface spraying, fireproof spraying, thermal insulation material spraying, ceiling spraying, wall spraying, paint spraying, garden spraying, relief effect paint spraying, handicraft spraying, Rockery spraying, sound-absorbing material spraying, waterproof plugging, waterproof leak repair, light and convenient for construction under bridges, dams, hillsides, basements, tunnels, and housing plants.
