- Q: Application characteristics of high alumina brick
- Reheating line change. If the firing temperature of high alumina brick products is enough and the firing time is enough, the volume is stable, the change of the reheating line is small; on the contrary, the residual shrinkage of clay brick products is caused by recrystallization.
- Q: What are the common thermal insulation materials for thermal conductivity?
- Aerogels are known to be the lightest solid materials in the world. It is made of nanometer silica aerogel as main material and is compounded by special process. The utility model has the advantages of high temperature resistance, low thermal conductivity, small density, high strength, green environment protection, waterproof and non inflammable performance. At the same time, with excellent sound insulation and shock absorption performance, it is now widely used in metallurgy, chemical, national defense, aerospace and other fields, is an indispensable high-performance insulation materials.
- Q: What is spalling resistant high alumina brick?
- Using bauxite as main raw materials, the introduction of a small amount of ZrO2 (ZrO2 is due to phase transition, between monoclinic and tetragonal type can improve the thermal stability of the products), adding a certain amount of binder and additives, the particle size distribution control mud, forming and sintering of refractory products produced, called anti stripping high alumina brick.
- Q: Are there any differences between insulating bricks and refractory bricks?
- Heat preservation brick is to emphasize its heat preservation performance generally, not paying much attention to its refractoriness, but refractory brick is exactly the opposite. Different locations will use different materials, I hope we can choose carefully.
- Q: How to distinguish the good or bad of the high aluminum brick?
- The general high alumina bricks used in the steel, steelmaking, hot blast furnace, electric furnace, blast furnace, reverberatory furnace, rotary kiln lining of industrial furnace in China, mainly composed of a bauxite; sillimanite minerals (including kyanite, andalusite, sillimanite etc.); synthetic material, such as alumina synthesis of mullite, corundum, etc.. High aluminum brick has good quality, high refractoriness, long life and other characteristics, is the main use of refractory brick kiln products, commonly used units can not distinguish the quality and grade of high aluminum brick right in the procurement time, caused by the high prices to buy low grade products, thereby reducing the furnace life therefore, Zhengzhou's Sindh yuan refractory material factory in here is simple to introduce how to identify the quality when purchasing brick high alumina brick.Color: in the purchase of high alumina brick, first of all to see the color, high quality aluminum brick surface smooth, yellow color white, four sides smooth, no broken angle, no cracksWeight: the weight of a block of bricks to be called, according to the standard weight level, high aluminum brick weight of 4.5 kg. Two grade high alumina brick weighs 4.2 kg, three high aluminum brick weighs 3.9 kg, the same level, the same parameters can reach this standard can be regarded as high-quality high aluminum bricks, the opposite is not up to the weight that the quality is good, if there is a crack, four angle uneven, off angle phenomenon, then substandard products, some of the above points to help to the purchaser
- Q: What does refractory consist of?
- Refractory materials can be divided into main raw materials and auxiliary raw materials according to their function in the production process of refractory materials.The main raw material is the main body of refractory. Auxiliary raw materials can be divided into binders and additives. The role of bonding agent is to make the refractory body in the production and use process has enough strength. There are commonly used lignin, phenolic resin, asphalt, cement, water glass, phosphoric acid and phosphate, sulfate, some main raw material itself has the effect of binder, such as clay; additive is to improve the production of refractory materials and construction technology, or strengthen the refractory material of some properties, such as stabilizer, water reducing agent, inhibitor, plasticizer, foaming agent, dispersing agent, bulking agent, antioxidant.
- Q: How to test the aluminium bricks of high alumina refractory bricks?
- Before making bricks, the raw materials are usually tested and tested to see if the aluminum content is up to standard
- Q: Does the chimney have high acid resistance?
- If it is an ordinary high alumina brick, it does not meet the requirements of acid resistance, and only the chimney lined with acid resistant bricks.
- Q: Use of high alumina refractory bricks?
- High alumina refractory brick in Al2O3 more, close to neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so alkaline slag ability than acid resistance slag ability less.It is widely used in building blast furnace, hot blast furnace, furnace top, blast furnace, reverberatory furnace and rotary kiln lining. In addition, high alumina bricks are widely used as furnace regenerative checker, pouring system for plug nozzle, etc..
- Q: What should be used as binder for making high alumina bricks?
- In addition, high alumina micro powder can be used as binding agent, or high alumina micro powder and clay powder are prepared according to a certain proportion, and synthetic mullite is used as bonding agent. With these binders, high alumina bricks without two expansion can be prepared.
