High Alumina Refractory Castable for blast furnace

Refractory castable,High alumina refractory castable,Alumina refractory castable

introduction :

Refractory castable is one of the unshaped refractory materials.It is made of refractory aggregate . refractory powder . binders and other additives. It is loose, No fixed shape,Has high liquidity, Casting and vibration molding,Can use directly or use after add appropriate water or other liquid. It is one of the new type refractory material of don't need calcination. In general the use of the site casting, vibration or tamping pouring molding method, a preform can also be made pre-formed components.

Features:

1. High refractoriness, High refractoriness under load.
2. High density, low porosity.
3. Good slag resistance and corrosion resistance.
4. High strength and wear resistance.

5. Good resistance to flake performance.

6. Good thermal shock stability.

7. Scouring resistance

Q: what's the seal of fireproofing material?: Organic fire-proof caulking is made by taking organic synthetic?resin as bond and compressing the components together after adding fireproofing agent, filler. The putty won't solidify after a long time usage and has good plasticity, can be sealed arbitrarily. This kind of putty is mainly applied in opening's fireproofing and sealing project of construction pipe and electric wire and cable, and it's used with ATD-AB and fire retardant bag together. ATD-AB is a kind of gray powder material, after mixed with water, it can be used for the opening sealing of electric wire and cable or fire resisting wall of wire tunnel. The fire proof blockage is non-toxic, and no smell, has good water resistance and oil resistance with simple construction methods. It's oxygen index is 100 and it belongs to incombustible?material. it's refractory time can reach 3 hours, or above or below. as for some projects for perpetual usage, WXY-II will save the project fee and make the project solid. A kind of fireproofing material that can automatically expand and foam and sealed by opening after injecting the foam into opening. Sealing strip is a product or flexibility coiled material mede by fireproofing material with certain geometry shape. Sealing gum is a kind of liquid fireproofing material that has a function of fireproofing and sealing. Fire retardant bag is soft and windable tape-shaped product made by fireproofing material, it is winded on the external surface of plastic pipe and fixed with steel belt or other proper methods, it's the expansion, squeezing and softening pipe after contacting with fire, opening left by burning or soften of seal plastic pipe. Fire retardant ring

Q: Can quantitative feeder be used in refractory plant? Thank you: Feeder experts, justice and analysis, quantitative feeder, of course, can be used in refractory plants

Q: Development trend of refractories: The foundation of China's refractories industry is still relatively weak, the utilization level of refractory material resources is low, the quality of refractory materials is not high, excess production capacity of ordinary products, the key products of some high-quality high technology content can be produced, but the quality is not stable, and the service life of refractory material consumption compared with foreign advanced level, there is a considerable gap. Therefore, the new trend of tracking foreign refractories science and technology development, carry out and supporting the development and application of advanced and basic theory research, to promote technological innovation of refractory materials, optimizing product structure, industrial structure adjustment, implementation of the strategy of sustainable development, it is very necessary.

Q: Who knows the model of fireproofing materials?: Inorganic binder: it mainly includes sodium silicate, gypsum, phosphate, cement,etc; refractory mineral filler: aluminium oxide, asbestos powder, calcium carbonate, perlite, cornstarch,etc; nonflammable organic resin: it mainly includes polyvinyl chloride, perchloro-ethylene, chlorinated rubber, neoprene latex, epoxy resin, phenol resin,etc. Nonflammable fireproof addictive: it mainly includes phosphorus, halogens, nitrogen organic compounds (chlorinated paraffins, TBP ( tributyl phosphate ), decabromodiphenyl ether), and borate series (boric acid, zinc borate, aluminium borate), antimony series, aluminium series, zirconium series and other inorganic compounds.

Q: How long is the duration of fire resistance that fireproof window of level B can endure?: Level B refers to the fire resistance rating and different hours in fireproofing of the fireproof window. Fireproof window of level A can endure fire for 1.5 hours while level B, 1.2 hours

Q: What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?: Blowpipe is also the construction of unshaped refractory materials. Refractory material for ladle cover is light weight heat insulation refractory material. What you said that the construction of bend out refractory materials in some steel mills called "knot".

Q: How to make use of waste refractory materials whose main elements are alumina and mullite?: Crushing and pressing refractory bricks, or refractory parts . Such as welding positioner tracks use disposable tools.

Q: What substitutes are available for high-end refractories in addition to zircon sand?: Natural ore, synthetic raw materials such as industrial synthetic mullite, etc..

Q: Who knows the roofing fireproofing and waterproof material?: If you should do home water proofing, I recommend the acrylate waterproof coating with high elasticity of Qinglong waterproof, because it has good aging resistance, extensibility, elasticity, binding property and film-forming property; waterproof layer is a closed system, the overall waterproof effects are very good, especially for the construction of heterotypic structure base and roofing, walls, toilet and bathroom, basement and other buildings waterproof and anti-seepage engineering in the conditions of non-permanent immersion;

Q: What are the main materials in concrete fireproofing material?: it can be roughly divided into: fire-resistant coating for steel structure, finishing fire retardant paint, tunnel fire coatings, concrete fire?retardant?coating, cable refractory coating. fire-resistant coating for steel structure is divided into: Indoor ultra-thin fireproof coatings for steel structure, indoor thin steel structure fireproofing coating, indoor thick steel structure fireproofing coating, outdoor ultra-thin fireproof coatings for steel structure, Outdoor thin steel structure fireproofing coating, outdoor thick steel fireproofing coating. I hope it can help you. Hope to adopt my opinion Thank you! )
