Q:What is the main component of corundum?
Corundum is the main component of Al2O3, often containing trace impurities such as Cr, Ti, Fe, V and so on.
Q:Is liquid phosphoric acid two aluminum hydrogen flammable?
Two aluminum liquid hydrogen phosphate using spray paint, cement, refractory castable and binder for foundry industry, mainly used in refractory industry corundum, chromium corundum nozzle coal water slurry gasifier with chromium aluminum zirconium corundum brick production.
Q:How do corundum bricks bind?
Each refractory brick is provided with corresponding refractory mud, and corundum bricks are bonded with corundum mud.
Q:Which is good, glazed brick and whole cast glazed brick?
The main advantages of all glazed glazed tiles are that they can be very rich and beautiful in texture and pattern, and they are suitable for family decoration, and can choose patterns according to their own family decoration style. Compared to the glazed tile, it has better pollutant discharge performance, and many pollutants are difficult to penetrate into it.
Q:What are the refractory materials?
Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 93% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, low thermal shock resistance. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used.
Q:What problems should we pay attention to in the use of fused zirconia corundum brick (fused zirconia corundum brick) in glass furnace?
The expansion curves of fused cast AZS brick at 1000 DEG C near a crystal anomaly, its internal changes of ZrO2 crystal are reversible, with large volume change, therefore, products containing ZrO2, should not be used in the temperature of 1000 DEG C, often have sharp fluctuations in the position. When baking the kiln, the temperature can not be too large at 900~1150 degrees centigrade. Generally, the temperature can not exceed 15 degrees /h, and the temperature should be raised steadily. Some parts to prevent the cold, with other brick protection, to prevent explosion.
Q:How much is a refractory brick?
There are many kinds of refractory bricks, you have to look at what is material, the material is not the same, the price is not the same, clay brick is the cheapest, probably hundreds of dollars a ton, and corundum brick a ton of several money, silicon carbide, silicon nitride, and more expensive. And this thing is generally on t sell, the price is by a single block after conversion.
Q:Expansion ratio of lightweight corundum refractory bricks
Light corundum refractory brick, because of its production methods and the introduction of different additives, there are certain differences in the content of Al2O3, just burn add general light corundum refractory brick and foam and gasification method cannot be made, the content of Al2O3 is generally not more than 99%, with alumina hollow ball manufacturing transfer are corundum brick with high content of Al2O3.
Q:What equipment is used for producing diamond blanks? How much is the investment?
Plus all the cables fifty thousand. Steel 10000 yuan. Corundum bricks; insulating bricks; clay bricks, these three require more than ten thousand. The electrode is about one hundred thousand. It's just an investment in an electric furnace. Together with the rear section processing and raw materials need hundreds of thousands of.
Q:What is the difference between corundum and high alumina?
The main components of high alumina brick are high alumina bauxite, mullite and partial corundum sand.The difference between them lies in the content of alumina and the alumina refractory products with alumina content higher than 48%The content of Al2O3 is higher than 90%, which is called corundum brick.
