Spraying technology of refractory spray coating

The refractory spray coating uses clay clinker as raw material, mixed with a variety of fine powder additives, cement as a bulk material made of binder, as a protective layer on the inner surface of the shell of the blast furnace, hot blast furnace, and the blast furnace head, gas outlet pipe, The working lining of the dust collector, but how much do you know about its spraying technology? Let me explain it to everyone.
The main principle of the spraying technology of refractory spray coating is to put the material on the square steel plate with anchor nails by hand according to different formulas before the construction of the kiln, and simply judge the bonding result, and determine the additives based on the results of the experiment. The proportion in the mix. At the same time, in the actual construction process, each squadron is gradually pushed forward and sprayed forward by a method of winding around the spring. The use range of this method is about 0.5 meters. Until the spray coating reaches the standard thickness, the distance between the spray gun and the surface of the workpiece to be sprayed must not be interrupted at the same time. Generally, the thickness of the spray coating must be accurately controlled at about 1 meter to improve the spray coating. Compactness and adhesion can also reduce its rebound rate and reduce material loss caused by modification.
Everyone has learned about the above-mentioned spraying technology of refractory spray coatings. I believe that everyone has learned something. I hope that everyone will apply it to the application. Then everyone can refer to the above content when spraying in the future, which can greatly improve work efficiency.
