150 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 150 mesh

Q: Which industry does refractory belong to? Does it belong to construction industry?: It belongs to material, and after all, more than 60% refractories are used in metallurgical industry. If you insist on classifying it, it belongs to supporting industry of metallurgical industry. Refractory industry itself is independent.

Q: How is the grading of the level A new material fire insulation material?: The thermal insulation materials are generally divided into level A and level B according to the flame rating. Level A is the non-combustible material, and level B is the combustible materials. The level B material is to blame for the fire in Shenyang hotel in CCTV building a few years ago . At present, the level A materials are widely used, with some prices even cheaper than the level B material. A level is roughly divided into insulation mortar, phenolic board, rock wool board and foam cement board, ect.

Q: For refractory knowledge. What is the ratio of clay ramming?mass?: Soil aggregates, dispersing agent, water reducing agent, plasticizer, binding agent and powder! ~ Bone meal feed approximately 6, OK

Q: What antioxidant will be used in refractories?: Specifically speaking, it is an antioxidant used in carbon refractory products, which belongs to the fire resistant technology. A kind of refractory used antioxidants, formula proportion is as follows calculated by weight percentage: aluminium zinc alloy 1 ~ 100, conventional antioxidants in 0 ~ 100. Described in the aluminum zinc alloy element of aluminum content is 3% ~ 3%, the rest is zinc. Described aluminium zinc alloy is powder or fibrous long; The biggest size and long fiber powder makeup of maximum diameter is 0.2 mm. Preparation of the present invention contains aluminum zinc alloy antioxidants can prevent carbon oxidation temperature range is big, less side effects, and can adjust the thermal expansion of refractory. Hope I 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

Q: What is the type of heat resistance property of high temperature electric furnace ?: According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃

Q: What are the characteristics of clay refractory materials?: Clay refractory has excellent performance in anti fatigue. The fatigue strength of the general metal is 50% ~ 40 of the tensile strength, and some composite materials can be as high as 70 ~ 80%. The fatigue fracture of the composite is from the matrix, which is gradually extended to the interface between the fiber and the matrix. Therefore, the composite material has omen before destruction, and it can be checked and remedied. Fiber composite material also has good performance in anti vibration fatigue. The fatigue life of The helicopter rotor made of composite material is longer that made of metal. I hope my answer will help you!

Q: What are the fireproofing materials of the external wall included?: According to the external wall thermal insulation materials, the external insulation materials is in general divided into Class A and Class B. The A class is non-combustible material. The B class is combustible materials. The fire disasters of the CCTV building and Shenyang hotel are both caused by the B level materials. Generally, the A level material will be used, and some prices are even cheaper than the B-grade material. A level is roughly divided into thermal?mortar, phenolic foam Board, rock wool board, foam cement board, and so on. I hope my answer will help you!
