Zircon Corundum Brick for Glass Furnace in China

Q:What refractory materials are used in industrial furnaces?: The working conditions of industrial furnaces should first be investigated thoroughly, and the primary and non essential factors affecting the construction of furnace materials shall be analyzed. Focus on thinking, the temperature change condition, temperature bump slag properties, furnace atmosphere, heat insulation, impact wear and other special requirements, to ensure the quality of the life and product.

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 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.

Q:Wave tile and throwing glaze, tile which good?: Vitreous tile is all ceramic tile, the material is hard, strong wear resistance, smooth finish is very good, in general, looks very bright. Microcrystalline brick, corundum brick Market said, they really mean bohuazhuan. Because of its low water absorption and high strength and hardness, glazed tile has been widely used. Many hotels, shopping malls and office space are widely used glass tile.

Q:What are the advantages of refractories?: Acid refractory material usually refers to refractories with SiO2 content greater than 93%. Its main characteristic is that it can resist acid slag corrosion at high temperature, but it is easy to react with alkaline slag.

Q:What is the main component of corundum?: Corundum is mainly used in advanced grinding materials, watches and precision mechanical bearing materials. A ruby based artificial crystal used as a laser emitting material. Ruby and sapphire are corundum minerals. Except for the starlight effect, only translucent transparent and vivid corundum can be used as gems. The red is called ruby, while the other tones of corundum are commercially referred to as sapphires.

Q:What is the difference between T3 refractory bricks and high alumina refractory bricks?: The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)

Q:What is the standard classification of high alumina bricks and high alumina bricks?: High alumina brick is a kind of refractory material in refractory brick products. It is made of refractory clay or other refractory material. It belongs to the product of Si Al System

Q:What kind of rock is corundum produced?: Aluminum oxide (Al2O3) mineral. Due to Mohs hardness of up to 9, mainly used as high-grade abrasives. The crystal belongs to the three party system, a dolioform six square column, some are needle or plate. Aggregates are massive or columnar. Usually white, gray, yellow and other colors. If a small amount of Cr3+ is red, a ruby is called;

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.
