White Fused Alumina product uses

White Fused Alumina is widely used in the refractory industry as it is a very pure low iron alumina suitable for a range of applications. Specific refractory applications include high tech refractory castables, isostatic pressed refractories and pre-cast refractory shapes. The benefits of White Fused Alumina in these applications are that it has a very high alumina content, low impurities and stability at high temperatures.

FAQ

Q3: Can you offer Door-to-Door delivery?

A3: Yes, but only for some countries such as U.S., UAE, Saudi Arabia, Iran, and Russia, etc.

Q4: What is the minimum quantity?

A4: There is no minimum order quantity. Depending on the item and processing, there may be a minimum production required, however we can offer a quotation based only on the quantity you need.

Q5: Can you give me a brief introduction of the application of your products?

A5: CNBM (China National Building Material) core refractory business comprises the production, sale and installation of high-grade refractory products, the development and implementation of customized system solutions as well as rendering outstanding services for the key industries in Glass, Iron& Steel, Petrochemical, Cement, Ceramic and Nonferrous Metals.

Q:What is the face brick: According to the shape and size can be divided into ordinary brick, standard brick, etc. can be used as a specific type of building furnace and various thermal equipment of high temperature building materials and structural materials, and at high temperature can withstand all kinds of physical and chemical changes and mechanical action.

Q:Outside wall tile (whole body smooth surface has small hole split brick) has cement pollution, with what product cleaning (cement, mortar, cleaning agent)?: Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels. Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks.

Q:What are the forming methods of refractory materials?: Casting molding is suitable for casting brick, electric melting brick and so on. And the machine press forming is the most widely used. The common refractory brick, clay brick and other sintered brick are adopted this method.

Q:How can the silica in zircon sand be removed during the smelting of zirconium corundum?: From the point of view of data analysis, there is no radioactive substance in it, and it will not cause harm to the human body.It is in the production process, zirconium corundum bricks are likely to cause pollution.Fused zirconia corundum brick is also called AZS AZS English is abbreviated to AZS, is based on three chemical composition of Al2O3 - Zr02 - Sio2 phase diagram of three component system, according to the content of the order, Al2O3 A, Zr02 Z, Sio2 S, national standards for the use of this abbreviation, such as No. 33 cast brick, abbreviated as AZS, 33#, No. 36 fused zirconium corundum brick, abbreviated as AZS, 36#, No. 41 fused zirconium corundum brick, abbreviated as AZS - 41#.

Q:What's the use of refractory bricks?: Refractory brick fire resistance is greater than 1580 degrees, and the average brick three or four Baidu softened deformation. The refractory brick because of its high refractoriness, and high pressure molding, and after high temperature kiln, so the use of strength is particularly good, practicality is particularly strong in high temperature liquid, gas with high temperature, high temperature solid, chemical corrosion products etc..

Q:What are kiln bricks?: Refractory materials are generally divided into two kinds, namely unshaped refractory and shaped refractory. Unshaped refractory castable is also called, is composed of a variety of aggregate or aggregate and one or more adhesive powder particles, and must use one or more liquid with stirring, has strong liquidity. Refractory materials generally refers to the shape of a refractory brick, standard rules, can also according to need to be cut when the temporary processing.

Q:What is brick power, half brick power and full brick power difference?: Power module. Small size, high power. General use should order additional storage energy, heat dissipation, etc.. Dimensions such as brick, so called brick power supply. Half brick power supply is half the size of all brick power supply.

Q:Zirconium corundum 25 content and 40 content, how to distinguish in appearance?: Fused zirconia corundum brick is also called AZS AZS English is abbreviated to AZS, is based on three chemical composition of Al2O3 - Zr02 - Sio2 phase diagram of three component system, according to the content of the order, Al2O3 A, Zr02 Z, Sio2 S, national standards for the use of this abbreviation, such as No. 33 cast brick, abbreviated as AZS, 33#, No. 36 fused zirconium corundum brick, abbreviated as AZS, 36#, No. 41 fused zirconium corundum brick, abbreviated as AZS - 41#.

Q:Can the fire clay be reused?: According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, ordinary brick, specific rotation. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature.

Q:How are qualitative and qualitative refractories understood?: Unshaped refractory products, referred to as bulk loading, are made at the place of use for the required shapes and for heat treatment, such as castable, ramming, projection, spray, refractory clay, etc..
