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.

| Bulk density | ≥1.9g/cm3 |
| RUL | ≥1250℃ |
| Refractoriness | ≥1500℃ |
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.

Traction control thermal wet spray technology is a new technology.
He pours the material into the blender of the wet-sprayer and adds
water to mix it evenly. Then cooperate with the remote control
thermal injection manipulator to adjust the angle and direction of
rotation, push the mixing material and accelerator together towards
the top of the spray gun, and the pourable material will propagate
through the blast furnace coating surface and condensed
immediately.
