Heavy Alkali Resistant Castable Definition
 
The heavy alkali resistant castables are made of refractory aggregates and powders, such as magnesium aluminate spinel and bauxite clinker, and doped with Al2O3 powder, the light alkali resistant refractory castables are made of low alumina clay lightweight aggregates, such as Shale ceramsite and so on. The binder of the two castables is CA-70 cement and CA-50 cement, together with alkali-resistant agent and ultrafine powder.
 
Heavy Alkali Resistant Castable Features
 
1.Castable refractory alkali resistant have high acid resistance
 
2.Castable refractory alkali resistant have corrosion resistance
 
3.Castable refractory alkali resistant have abrasion resistance
 
4.Castable refractory alkali resistant have peeling resistance
 
5.Castable refractory alkali resistant have thermal shock resistance
 
6.The formation of a crust anti erosion protective layer on the surface at high temperature can effectively prevent the alkaline gas flow in the cement kiln material at high temperature and the erosion and penetration of the material into the heavy alkali resistant proof castable body.
 
7.Heavy alkali resistant castables have the advantages of high strength and low castable refractory alkali resistant density.
 
Heavy Alkali Resistant Castable Specification
 

 
Heavy Alkali Resistant Castable Application
 
1. Alkaline resistant castable used in cement rotary kiln kiln and kiln decomposition cyclone lining, roasting alumina rotary kiln lining lining. As well as steel, non ferrous, glass, paper and other industries, industrial furnaces with alkali vapor corrosion and their flue and smoke Window lining.
 
2. Alkaline resistant castable used in large and medium sized dry process cement kiln coal injection nozzles and kiln mouths, preheaters and pipelines.
 
3. Alkaline resistant castable is used in the alkali recovery furnace of the paper industry to obtain better results.
 
4. Castable refractory alkali resistant mainly used as lining and sealing material for industrial furnace thermal equipment.
 
5. Alkaline resistant castable applicable to small blast furnace hearth in cement kiln, power frequency induction electric furnace melting tank, soaking furnace desulfurization hood, blast furnace air duct rotary kiln and various flue, acid, trough and other parts.
 
Heavy Alkali Resistant Castable Pouring method
 
1.The alkali resistant castable has good fluidity, the casting method of the alkali resistant castable can be castable by plastic molding, so Castable refractory alkali resistant is most suitable for this method.
 
2.The plastic molding method is a method of forming a plastic alkali resistant castable having a water content of 18% or more into an embryo body. The prefabricated blank is put into a slimming device, extruded into a mud strip, cut into a block by a cutting device, and the blank is made according to the required size, the blank is pressed to make the blank have a prescribed size and shape.
 
3.Heavy Alkaline Resistant Castable Precautions
 
The moldable pouring alkali resistant castable body has large moisture, low brick strength, inaccurate shape and complicated drying process, the proportion of shrinkage is too large to reach more than 10%. Therefore, in the production of alkali resistant castable products, except for some products In addition, less plastic molding method.
 
Heavy Alkali Resistant Castable Advantage
 
1.The formation of a crust anti erosion protective layer on the surface at high temperature can effectively prevent the alkaline gas flow in the cement kiln material at high temperature and the erosion and penetration of the material into the alkaline resistant castable body.
 
1. The alkali resistant refractory castable adopts materials such as fused corundum, zirconium corundum, magnesia, magnesium aluminate spinel, chrome ore and zircon as refractory aggregates and powders, alumina casting cement and admixture are used to prepare castables. It is used in the alkali recovery furnace of the paper industry to obtain better results.
 
Heavy Alkali Resistant Castable Selection
 
The density of the alkali resistant castable is directly related to the rheology. If the rheology is not good, the density of the alkali resistant castable is greatly reduced, the rheology is inseparable from the particles. Less, the density of the alkali-resistant castable is also conceivable, so the particle content must be sufficient, so that the alkali-resistant castable is more compact. The density of the alkali resistant castables is also related to the bubbles because the bubbles can not take up the place, which occupies a large area. The density of the alkali resistant castables cannot be compact, the reason why the bubbles cannot be eliminated is the moisture. Insufficient, if the water is enough, then the problem of bubbles will be solved, so the alkali resistant castables will definitely be more compact because there is no bubble. Therefore, moisture is also an extremely important factor. The last reason, that is, the particles, the density of the particles is large, it is compact, and the density of the alkali-resistant castables is much smaller, so we must choose when choosing particles. In the case of large particles with sufficient components, the density of the alkali-resistant castables will be more compact.
