- Q: What is fireproof concrete?
- Silicate fireproof heat-resistant concrete using temperature can reach 700 DEG ~800 DEG, the main mechanism of its heat is dehydrated calcium hydroxide silicate hydrates series of cement clinker under high temperature, the calcium oxide and slag and mixing activated silica material in the three and two aluminum oxide and the reaction of anhydrous calcium silicate and anhydrous aluminum acid calcium has strong heat resistance, the fire resistance of concrete is a certain. Such as the use of high alumina bauxite and broken bricks, magnesia brick and magnesia for fireproof heat-resistant concrete materials with the highest using temperature can reach 1100 DEG C.
- Q: What are the reasons for the spalling of refractory bricks in the production of lime kiln?
- Therefore, the choice and masonry of refractory bricks are of vital importance. If there is a brick kiln kiln off block process of reproduction, is now because of the use of refractory brick kiln material mostly three grade high alumina bricks. The content of AL2O3 is about 55%, of which the content of Fe2O3 is about 2%, which is weak, and the alkali corrosion resistance is a little worse. In a containing three grade high alumina bricks in the composition of AL2O3, Si2O3, and other elements also contain K, Na trace, were the most, thus causing the system of the low melting point is very low, even at 1400 DEG C has been liquid phase, and generate CaAL12O19 limestone and calcium feldspar etc.. Form corrosion loss. Therefore, a long time will cause the loss of block. On the one hand, it may be caused by construction.
- 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 are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?
- All the raw materials adding order, mixing time, material and material moisture trapped. 4, the pressure and the volume density of Pei brick and brick Pei size etc..
- Q: Aluminum content 38, silicon content 55 What refractory bricks?
- Hello Only on behalf of the Zhengzhou colt as refractory product index your answer to this question is not entirely separate from the chemical index of aluminum content, silicon content and judgment, personally think that three types of refractory bricks may respectively is: Two: semisilica brick high alumina brick
- Q: What are the characteristics of high alumina bricks?
- A neutral refractory with an alumina content of more than 48%. Made from alumina or other raw materials of high alumina content; formed and calcined.
- Q: What are the requirements for refractory materials in heat treatment furnace?
- Fire resistance is an important performance index of refractory materials, but it does not represent the highest temperature in actual use of refractory materials. In actual use, refractories also bear certain pressure, therefore, must consider the high strength at high temperature refractory material, which is in high temperature under certain pressure without deformation, such as the NZ-40 refractory refractory degree up to 1730 DEG C, but the maximum temperature is only 1350 degrees celsius.
- Q: How high can aluminum bricks expand at 80O degrees of heat?
- The expansion of high alumina brick is not only related to temperature, but also related to its material composition. The refractory temperature of high alumina brick is above 1770 centigrade. The temperature of 800 DEG C has little influence on the expansion of high alumina brick.
- Q: How does the physicochemical index change when the high alumina brick is used at high temperature?
- If the range of softening temperature exceeds the load, the constants of other physical and chemical indexes will also increase or decrease.
- 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.
