High Alumina Gunning 1.65g/cm3 Steel Making Refractories
 
High Alumina Gunning Refractory Materia is an amorphous refractory material made by mechanical spraying method using pneumatic tools.
High Alumina Gunning Refractory Materia consists of refractory agglomerates, powders and binders (or additives).
 
Due to the repetitive continuous effect of cement and aggregates and other material components during the spraying process to promote condensation of the sprayed materials, the sprayed layer has better density and mechanical strength.
 

 
High Alumina Gunning Refractory Material are classified into light spray coating, medium and heavy spray coating and heavy spray coating depending on the bulk density of the material.
 
The High Alumina Gunning Refractory Material is used as thermal insulation and thermal insulation coating, medium and heavy spray paint can be used as thermal insulation coating, while the heavy spray paint is mainly used as thermal insulation coating. work.
 
High Alumina Gunning Refractory Material has become one of the most important amorphous refractories used in many industrial furnace linings.
 
The High Alumina Gunning Refractory Material can be used to make and repair the furnace lining and the lining in a protective layer in the cold state, and is also suitable for the repair of the furnace lining in the hot state.
 
Construction method:
 
Cement refractory structures combine transport, injection or compression processes. There is no mounting or only one side, the process is simple, efficient and widely applicable.
 
Depending on the order of addition of water (or solution) and the amount of water, gel refractories can be divided into three types: wet, semi-dry and dry.
 
The wet method involves mixing the spray material into the suspension prior to spraying.
 
The semi-dry method involves first wetting the spray material, pressing the nozzle, then adding the remaining water (or solution), and includes all water consumption (or solution) of the drying method. The most common of them is the semi-dry method.
 
Process Characteristics Fire resistant spray material is sprayed.
 
The material mixing ratio, spraying operation, rebound rate, and processing characteristics are as follows.
 
The mixing ratio of the spray coating must meet the following conditions: Achieve the required strength, reduce backlash, reduce spray dust, good adhesion and do not cause pipeline clogging.
 
When using a cement binder for dry or semi-dry spray, the amount of cement is about a quarter of all materials.
 
Too much cement increases the amount of dust during spraying and increases the shrinkage of the spray layer after hardening.
 
Spraying plays an important role in ensuring the quality and recoil of the spray paint.
 
Controls the distance from the nozzle to the spraying surface.
 
In general, the nozzle should be perpendicular to the spray surface, move along a spiral path and regulate the air pressure of the spray.
 
The thickness of the spray should not allow the spray to slip or fall off, but the coating thickness of each auxiliary spray should not be too thin to avoid increasing the rate of repulsion.
