72 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.

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.

abrasive white fused alumina (WFA) for sand blasting 72 mesh

Q:What types does soft fire prevention materials have?: Species: Finishing fire retardant paint, component fire retardant coating, fire-resistant coating for steel structure and othe kinds of fire retardant coating. Flame retardant plastics and its products, textiles, building materials, flame retardant fabric and exterior wall thermal insulation system products, floor materials, such as various types of fire prevention materials;Fire prevention board, fire doors, fire resistant window frame.

Q:Does anyone know the refractory temperature of fire-resistant glass?: Ordinary glass will burst under sharp temperature difference of about 70-120 degrees and toughened glass of 200 degrees. It is not yet clear for the bursting temperature differences of the refractory glass. If the overall glass is heated evenly, it will have no significant change below 600 degrees, and it will deform with the increase of temperature until melting. The fire-resistant time of the glass you said is the time to heat the glass into the extreme temperature differences it can endure, which should not be more than 10 minutes

Q:What are the new refractories?: There are many of them. We can talk face to face. Sichuan Province Deyang City Xinxin Refractories Co. 0838-2228543

Q:what kind of refractories is used to make the industrial silicon furnace mouth long life?: Fused zirconia corundum brick, the smelter of the glassworks is used this kind of lining, and you can contact by private letter.

Q:What is the offer of fire proofing thermal insulation material?: The following prices are from the Internet and for your reference only. Hainan fire proofing thermal insulation material ceramic fiber paper aluminum silicate fiber blanket/aluminum oxide fiber insulation cotton insulation pipe 12 yuan Hainan multicrystal mullite/calcium silicate corundum ceramic fiber loose wool short fiber fire proofing thermal insulation material non-asbestos high temperature resistant aluminum silicate fiber insulation cotton fire-resistant material ceramic fiber blanket thermal insulation blanket 28 yuan non-asbestos high temperature resistant aluminum silicate fiber ceramic fiber blanket needled felts insulation blanket fire resistant material thermal insulation cotton blanket reference price: 59 yuan

Q:What are the fire resistances of grc partition panels?: A-level fireproofing which can last for 4 hours.

Q:Who know about the knowledge of acid refractory material? Please explain in detail.: Refers to the silicon dioxide

Q:How to determine the fire resistance rating of the aluminium-plastic?panel?: Class A incombustible and thermal insulation material: inorganic active wall thermal insulation material, cement foam insulation board, glass bead thermal mortar, rock wool board, glass wool board, foam ceramics, etc. With many characteristics of low density, low thermal conductivity, high pressure bearing capacity, convenience of construction, economy and durability, A class incombustible material is widely used as thermal insulation material for heat pipelines, thermal equipment, other industrial pipe-line equipment and industrial buildings, and thermal insualtion and sound absorption material for the building envelop of industrial and civil buildings. Because of good thermal stability, it is more often used as fire-proof and protective coating material of the steel structure.

Q:What kind of refractory bricks material is best?: 1, high alumina brick: The content of Al2O3 is more than 75. The refractoriness is higher than the clay brick. It has good resistance to acid, alkali and erosion and is suitable for cement kiln calcining zone and other places. It has long operation life, but the price is high. 2. dolomite?brick: Formation of coating has good performance, good corrosion resistance, but f-CaO is contained in bricks. It is hydratable and difficult to transport and keep, so it is less used in the production. 3. magnesia-chrome bricks: It has good formation of coating and is used for burning zone. The disadvantage is poor thermal shock resistant performance. Besides, positive Hexavalent Cr is highly toxic. Countries that produce and use magnesia-chrome bricks gradually decrease on the international. Now production units using this brick should find alternatives as soon as possible. 4. spinel brick: It is often used in transitional zone and has good seismic performance, good reduction resistance, but refractoriness is a little bit poor. 5. anti-stripping brick: This brick contains a small amount of ZrO. Martensite phase transformation happens to form thin crack during temperature-rise period. It has strong alkali?resistance, anti-stripping performance and good slag resistance. 6. phosphate brick: It has low refractoriness, but it has strong strength and good shock resistance. It is often used in grate?cooler, hot kiln hood, etc. 7. carborundum brick: It has high temperature resistance(1800 degree, softening temperature under a fixed load is 1620-1640), small coefficient of thermal expansion, high cold-resistance heat-resistance, abrasion resistance. It is suitable for cooling zone and kilneye. 8. silmo brick: It has good thermal shock resistance, high strength, good abrasion resistance, and is suitable for transitional belt.

Q:What are the main characteristics of the sic refractories?: The physical properties of SiC refractories include structural properties, thermal properties, mechanical properties, usability and job performance. The structural properties of refractory include porosity, bulk density, water absorption, air permeability, an the distribution of pore size. The thermal properties of refractory include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity, and thermal emission rate. The mechanical properties of refractories include withstand voltage strength, tensile strength, anti bending strength, torsional strength, shear strength, impact strength, abrasion resistance, creep resistance, adhesive strength, and elasticity modulus. The usability of refractories include refractoriness, load softening temperature, linear?change?on?reheating, thermal shock resistant performance, slag resistance, acid resistance, alkali resistance, hydration resistance, corrosion resistance to CO, conductivity, and inoxidizability.
