Corundum bricks are high alumina refractory fire bricks
made for extreme demands. The alumina content in corundum brick is from
synthetic corundum of high purity, such as white fused alumina or
tabular alumina. Additional ingredients are special refractory clays, reactive alumina, and very pure modifications of silica. Corundum bricks are fired at high temperatures to form a matrix with mullite, mullite-corundum or corundum that has excellent volume stability.
The service temperature for corundum brick
goes up to 1800°C. Corundum bricks can be used in nearly all fields of
industrial application where extreme high temperature and increased
resistance against aggressive slags and atmospheres are necessary. Such
properties or features of corundum bricks are necessary especially in
the chemical industry and for the production of carbon black. The
addition of chromium oxide, zirconium oxide, and phosphates gives the refractory
bricks excellent structural flexibility, which is required for ash
melting furnaces and gas reactors in incinerators. Wanhao Refractory
distributes Corundum Bricks of the best quality at the most competitive
prices with our fast, responsive customer service and reliable delivery
service.

Our main products include: Graphite electrodes for aluminum smelting Graphite electrodes for the steel and iron industry UHP Graphite Electrodes HP Graphite Electrode RP Graphite Electrode Wanhao is a manufacturer who is specialized in designing various kinds of...
Graphite electrodes are widely used in Industrial arc furnace, Steel mills, Foundries, or other metallic and nonmetallic materials, etc. HP Graphite electrodes are used in EAF and LF for steel making, as well as in electric smelting furnace for producing industrial silicon, phosphorus, etc. The regular power, high-power graphite electrode and ultra-high-power graphite electrodes are of low resistivity, resistance to oxidization and corrosion, high mechanical strength, good resistance to shake, good heat enduring, low ash content. HP Graphite electrodes is widely used in smelting alloy steel or other metal and refractory materials in metallurgy industry. Our company also manages graphite pieces, coke, tar and many other products. Wanhao refractory can process graphite crucibles, graphite electrodes, sticks, rings, pipes, and graphite boat. Graphite electrodes market finally starts to pick up this spring after nearly two sluggish years. Prices of UHP graphite elec...
The properties of magnesia are classified into chemical and physical properties.The chemical properties of magnesia sand is mainly refer to the periclase. Mgo is the main component in the periclase. Periclase is one of the most common minerals in cement clinker. It can coexist with four kinds of main mineral C3S, C2S, C3A, C4AF in the cement clinker. So periclase has good erosion resistance against cement clinker. （1）Periclase has very high melting point so that the magnesia refractories are charactorized with good high-temperature resistance. （2）Periclase has good thermal conductivity. When using high mgo content refractory , and the kiln skin can not be hung, the surface temperature of kiln body will raise. At that time, not only it will cause a great loss of heat dissipation, but also easy to burn the cylinder. （3）Periclase has high thermal conductivity. So that the thermal shock resistance for magnesia refractories are not enough. In the process of using, t...
