What are the different ways of gunning material


1 Wet gunning is a method in which refractory aggregates, binders, additives water are mixed to form a slurry with a certain consistency, then the slurry is sprayed onto the gunning surface with compressed air through a gunning machine. Ladle magnesia carbon bricks are characterized by simple operation, high adhesion rate rapid sintering. However, due to the high water content finer grain size, the shrinkage is also greater. At the same time, because the gunning layer is thinner, the durability is very good.


2 Semi-dry gunning is a method in which refractory aggregates, binders, additives, etc. are mixed with water through the water ring holes on the spray gun sprayed onto the gunning surface by compressed air. The dosage can be adjusted at any time according to the spraying situation, generally fluctuates between 10-20%, which is much lower than the wet spraying water consumption. Therefore, the gunning layer has a large volume density, less shrinkage, a thicker gunning layer can be obtained. It has better durability, but the rebound amount is slightly higher than that of the wet method. This gunning method is more common. Unshaped refractories used for gunning construction with jetting machines. It is composed of refractory aggregates powders with a certain particle size, binders additives. According to the material, there are alkaline, aluminum silicate, zirconium-containing silicon carbide-containing.
