                       60 mesh abrasive white fused alumina (WFA) for sand blasting

White Fused Alumina/ WFA

White Fused Alumina, a kind of high-grade refractories, was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.

Advantages

Flexible price policy

Equipped full line of test method.

As refractoriness

White Fused Alumina is the main starting material to produce high-grade unshaped and shaped refractoriness and is widely used in the field of iron-steel industry,ceramics,petrochemical industry etc. It is the ideal material to produce the unshaped refractoriness such as large ladle castables,medium and high grade BF trough castables,gunning material,pre-cast shapes and is the main material to produce alumina products such as corundum bricks, corundum and mullite-corundum sagger,refined porous plug bricks, monolithic lance composite nozzle, lining material for high temperature industrial furnaces,etc.

As abrasives

White Fused Alumina can be used as consolidation & coating abrasives, wet or dry sprayed grit, suitable for ultra-precise grinding and polishing in the crystal and electronic industry and can be used to produce high-grade refractoriness. It is suitable to machine high stiffness &high tensile strength materials such as chilled steel, alloyed steel, high-speed steel, high carbon steel, etc. In addition, it can be used as catalyst, insulator, precise foundry sand, etc.

Q:Manganese steel belongs to refractories
NO!
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:As for fireproofing material rock wool and glass wool, which one is better?
Rock wool board and glass wool board are a kind of new construction thermal insulation material, it's widely applied in construction and has replaced traditional thermal insulation material to some degree. With the gradually deepening study of rock wool board, glass wool board, we can find that these insulation materials have advantages in many aspects but there are also many deficiencies, particularly there exists a lot of controversy about the impact on the human body. The production process of rock wool board and glass wool board usually includes: after melting in high temperature of rock or glass, inorganic fiber is produced by high-speed centrifugation equipment, and at the same time add binder,dust laying oil,silicone oil at certain proportion, then produce sheet material according to different requirements. It has good thermal insulation properties, mechanical property, sound absorption characteristics, belong to incombustible material and is cheap. In general, insulation, security and economy should not be contradictory, three aspects should be taken into account, balanced chosen and developed. Rock wool board and glass wool board and other such materials should be properly selected and applied to the appropriate structure, so that the choice of material will play their strengths and avoid their weaknesses.
Q:Fefractory of aluminium oxide.
Do you mean the alumina hollow ball brick? We can exchange private messages in specific.
Q:The structure of refractory material
Q:Which are fire proofing thermal insulation materials?
Which are fire proofing thermal insulation materials? Which fire proofing thermal insulation materials are commonly seen?
Q:How many levels are there in the classification of PP fireproof materials?
The level of fireproof materials: A-level: Non-combustible building materials have rare chance to burn. A1-level: Non-combustible materials, no open fire A2-level: Non-combustible materials, smoke should be tested and qualified. B1-level: Fire-retardant building materials: Fire-retardant materials are good at resisting flame. It is difficult for them to burst into fire when coming across open fire in the air or at high temperature. It will not quickly get wilder and when the fire source removes, it will be extinguished immediately. B2-level: Combustible building materials: Combustible building materials can play a certain role in preventing combustion. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden pillars, roof frames and beams as well as stairs. B3-level: Inflammable building materials are highly flammable with no flame retardant ability, fire risk is high.
Q:What's the fire endurance of hollow brick?
Light weight, high strength, thermal insulation, sound insulation and noise reduction. environmental protection, no pollution, the ideal filling material of frame structure building, Disadvantages:: poor seismic performance, fire reistance being less than 1000 ℃.
Q:Does anyone know about the A-level fireproof materials?
A1-level fireproof materials include: 1. inorganic materials: glass wool, rock wool, foam glass,etc. 2. organic materials: phenolic foam insulation composite board. I hope my answer can help you.
Q:what is the common materials for home fireproofing material?
1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof panel, 7.gypsum board Hope to adopt my opinion
