The foundry refractory manufacturer will take you to understand some precautions for the spraying construction of refractory spray coatings

The foundry refractory manufacturer tells you to set Y-shaped and T-shaped metal anchors of two different specifications on the sprayed inner lining. Welding process for welding.

The spraying construction process is: pouring - stirring - sieving - air supply, water supply, material feeding - spraying material - trimming - cleaning. The construction of spray paint is generally relatively simple, no mold is required, only a spray gun is needed to spray paint.
The foundry refractory manufacturer tells you to place the batching station, spraying equipment such as air compressors, and spray guns near the spraying work before spraying, so as to better operate the working pressure of the spraying machinery and delivery pipes.
The requirements for spraying equipment are: air compressor 0.6Mpa, spray gun 0.4Mpa, spray gun spray pressure 0.1-0.2Mpa.
When spraying, the nozzle should be kept perpendicular to the sprayed surface and at a distance of about 0.8-1.2m, and move evenly from top to bottom in a spiral shape during spraying.
The foundry refractory manufacturer tells you to pay attention to the speed of the material flow at the nozzle when spraying, to avoid dry material and flow during the spraying process, and it is better to have a small amount of rebound, less dust, dense spraying, no interlayer, and a smooth surface.
The foundry refractory manufacturer tells you to check the spray thickness after spraying, if it is less than the design thickness, it should be re-sprayed in time. The quality of the sprayed lining is not only related to the material itself, but also the construction.
