Cold crushing strength Cold crushing strength is the ultimate load per unit area of dense shaped refractory products can withstand without damage at room temperature. The cold crushing strength of pressure-resistant refractory products has a great impact for the production, transportation and use performance, so higher cold crushing strength is better. The high crushing strength indicates that the processed quality is good, structure is uniform, and well sintered. High temperature crushing strength High-temperature crushing strength is the refractory products under the specified high temperature conditions, the unit area can withstand without damage. The high temperature crushing strength of refractory products determines the use scope, which is an important basis for the use of refractory materials . High temperature crushing strength indexes are also meaningful to unshaped refractories, especially refractory castables and fire-resistant plast...

The unfired brick is a kind of refractory which is can directly used for constructiion use without adobe firing. Its production process is very simple. It is made by different refractory material after resonable gradation,then bonded with organic or inorganic cementing agent that has strong binding capacity. The main type of unfired brick (1) High alumina brick with the combination of aluminate cement  (2) Clay brick Combined with Portland cement (3) High alumina bricks with the combination of industrial phosphoric acid and aluminium phosphate (4) High alumina brick with sulfate binding (5) Ordinary brick with water glass combination (6) Magnesia brick with combination of magnesium chloride and Magnesium Sulfate. The advantage of unfired brick is good shock resistance. The defect is lower high temperature crushing strength than fired brick. So it can’t be used in the load-bearing part.

High alumina brick is a kind of refractory , whose main component is Al2O3. For example, Al2O3 is high than 90$, called as corundom brick. Because of different resources, different countries have different standards. For example, European countries regulate that the lowest limit of Al2O3 is 42%. And in China, high alumina brick is divided into three classes based on Al2O3 component. Ⅰclass──Al2O3 >75%；Ⅱclass──Al2O3 is about 60～75%；Ⅲ class──Al2O3 is about 48～60%. Mainly used for masonry blast furnace, hot stove, furnace top, blast furnace, reverberatory furnace, rotary kiln lining. In addition, high alumina brick is also widely used as open hearth regenerative checker bricks, gating system with plug head, outlet brick. But the price of high-alumina brick clay brick than high, so with clay brick to meet the requirements of the place do not have to use high-alumina brick.

Fused zirconia corundum fire brick , also known as AZS fused zirconia corundum brick abbreviation is AZS. It is based on the chemical composition of three Al2O3-Zr02-Sio2 ternary phase diagram. According to their order of content, Al2O3 takes A, Zr02 takes Z, Sio2 takes S. The national standards adopted this abbreviation, for example, number 33 casting zirconia corundum brick, abbreviated as AZS-33 #, 36 cast zirconia corundum brick, abbreviated as AZS-36 #, No. 41 cast AZS bricks, abbreviated AZS-41 #. Fused zirconia corundum brick is pure alumina powder containing 65% zirconium oxide, silicon dioxide about 34% of zircon sand, in the electric furnace to melt within the injection of cooling within the model and the formation of a white solid, rock phase structure consisting of corundum and zircon stone ramp and a glass of eutectoid phase, to learn from in terms of phase and zirconium corundum stone ramp eutectoid phase, the glass phase is filled between them crystals. ...

Magnesite is the main refractory raw material for magnesia carbon brick , normally there are two kinds, sintered magnesite and fused magnesite. Bu comparing this two kinds, fused magnesite has the advantages of lager periclase crystal, bigger bulk density, etc.it is the priority raw material for producing magnesia carbon bricks . When producing normal magnesia based refractory material, the requirements on megnesite are high temperature resistance and erosion resistance, thus the purity of magnesite, C/S ratio and B2O3 content are important. With the development of metallurgy industry, the smelting condition is becoming harder, the requirement of megnesite used for producing magnesia carbon brick used in smelting equipment(such as Converter, EAF, Ladle) is not only on the chemical composition, but also on structure like high density and large crystal. There have many kinds of refractory products in our factory. Such as fire brick for sale, refractory raw material,  ...

Brown fused alumina is based on bauxite, coke as the main raw material, then melting in the electric furnace with high temperature.The abrasive tools that made of brown fused alumina is suitable for grinding high tensile metal,like general steel,malleable cast iron, hard bronze, etc.,also can be used in making high grade refractory . Brown fused alumina is charactized with high purity,good crystallization,strong liquidity,lower linear expansion rate and erosion resistance. Application: 1.It is used to make high grade refractory ,castable, firebrick etc. 2.Sand blasting--moderate hardness, high packing density, no free silica, large density, good toughness, it is the ideal "environmental protection" type sandblasting materials. 3.Free grinding.It is general domestic high grade abrasive material that is used in the field of  image tube, optical glass, monocrystalline silicon, lens, glass, crystal glass, jade, etc., 4.Resin grinder 5.Coated abrasives--It is t...
