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.

White Fused Alumina applications

Gunning materials
Mouldable and Ramming Refractory Mixes
Recycled refractory minerals
Refractory castables
Refractory mineral blends
Refractory mortars
Refractory raw materials
Toll processing

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: How can the silica in zircon sand be removed during the smelting of zirconium corundum?: Fused zirconia corundum brick is pure alumina and zirconia containing silica 65%, about 34% of the zircon sand in electric furnace melting after internalization into moulds cooling and the formation of the white solid, the petrographic structure by zirconium corundum and plagioclase eutectoid and glass phases, from the phase is eutectoid zirconium corundum and plagioclase phase, glass phase filling between their crystallization.

Q: What is brick power, half brick power and full brick power difference?: All brick power up to 500 watts up and down. The internal circuit is tight and heating, the device has good adhesion, the circuit is more advanced, and the efficiency is high, so it can achieve small size and high power.

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..

Q: What are the forming methods of refractory materials?: Basically there are three kinds: grouting molding, casting molding, machine forming, the three methods are applicable to different types of refractory materials, grouting molding for unshaped refractory

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: 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: Is the wall around the fire area using a firewall? What's the difference between a fireproof brick and a regular brick?: Fire bricks burn well!!In fact, the firewall does not necessarily have to use the so-called "fire brick", but to see the brick fire limit!240, the fire limit seems to be 4 hours, 370 I do not remember clearly, fire codes have, you see, do not think so naive!

Q: Outside wall tile (whole body smooth surface has small hole split brick) has cement pollution, with what product cleaning (cement, mortar, cleaning agent)?: Tile has a long period of cement pollution, a variety of weak acid cleaning can be removed, such as oxalic acid, acetic acid and so on, of course, the use of special cleaning agent is perfect. But the cost is higher.

Q: What material is good for refractory bricks?: According to the composition of refractory bricks, they can be divided into five major categories, namely, silicon aluminum refractory bricks, basic series refractory bricks, carbon containing refractory bricks, zirconium containing refractory bricks and insulating refractory bricks.

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..
