High Strength 60 Al2O3 1.9g Density Gunning Refractory Material
Gunning Refractory Material is an unformed refractory material made by mechanical spraying with pneumatic tools.
Gunning Refractory Material consists of refractory fillers, powders and binders (or additives).
Due to the repeated continuous exposure of cement and aggregates and other components of the materials during the spraying process to promote densification of the Gunning Refractory Material, the sprayed layer has better density and mechanical strength.
| Item | Chemical Composition |
| Bulk density | ≥1.9g/cm3 |
| RUL | ≥1250℃ |
| Refractoriness | ≥1500℃ |
Gunning Refractory Material are classified into light spray coatings, medium and heavy spray coatings, and heavy duty spray coatings according to the bulk density of the material.
Light refractory Gunning Refractory Material is used as heat-protecting and heat-insulating substrate, medium and heavy-duty spray paint can be used as heat-insulating substrate, while heavy-duty spray paint is mainly used as working substrate.
Gunning Refractory Material has become one of the major unformed refractory materials used in many industrial furnace linings.
Gunning Refractory Material can be used to build up and repair the furnace lining and coating in a cold condition and repair it in a protective layer, and it is suitable for repairing the lining of the furnace in a hot condition
Processing procedure for blast furnace lining:
1 Prepare the machine
2 Control temperature control (<110 ℃) and gas (<50 ppm)
3 Clean the oven wall and the cooling rod
4 Mixing material
5 Adjust the machine to the thickness and height of the spray
Spray the manipulator
package:
Ton bag packaging is suitable for sea transportation
Basic Info.
Supply Capacity
Clear Control of Hot Wet Spray Technology - this is a new technology that pours the material into the wet spray blender and adds water to mix them evenly. Then, in coordination with the remote control of the hot spray manipulator, adjusting the angle of rotation and direction, the mixed material is pushed to the nozzle with the accelerator, the casting spreads over the coating surface of the blast furnace and immediately solidifies.
