Product Description:

White Fused Alumina

 

Our WFA grains are produced from high purity calcined or feedstock alumina in electric arc-furnaces. The molten material undergoes cooling, crushing, grinding, sieving, classifying and, of course, various quality checking procedure before it is packed for delivery. 

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.

Q:What are kiln bricks?
Kiln brick masonry brick kiln used brick, brick is a brick kiln.
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 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:Just what is in the furnace material?
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. For example, refractory clay brick, high alumina brick, brick, brick etc..
Q:What is the face brick
You should be talking about refractory bricksThe refractory brick brick. Referred to as refractory material has a certain shape and size. According to the preparation process can be divided into bricks, brick, electric melting brick, refractory insulating bricks (Rong Zhuzhuan);
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 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?
Shaped refractory products, such as fired brick, fused brick (Rong Zhuzhuan), refractory insulation bricks, as well as experimental and industrial crucibles, utensils and other special products.
