The Basic Features of High Alumina Refractory Materials

High alumina refractory materials feature high Al2O3 content, so its high temperature properties are better than fire clay refractory materials. As can be seen from the phase diagram of Al2O3-SiO2 system, when the content of Al2O3 is less than 72%, the only stable high temperature solid phase at 1850℃ is mullite. Some SiO2 is composed of mullite and the remaining SiO2 forms a liquid phase at high temperatures. When the composition of high alumina refractory materials is close to the composition of mullite (71.8% Al2O3, 28.2% SiO2), the amount of liquid phase decreases and the refractory property is enhanced. Therefore, for high alumina bricks with an Al2O3 content of less than 72%, with increase of Al2O3, mullite increases and refractory property increases correspondingly; for high al... Read more

In our life, the application of ceramic fiber blanket is very wide, so in order to let everyone use it better, we need to understand it in particular, we bring some quality standards knowledge to everyone.
1. The lining thickness of ceramic fiber blanket must meet the requirements.
2. The Al2O3 content is not less than 45%.
3. Ceramic fiber blanket should be carried out before the test row, the layer should be sticky solid, gap staggered.
4. After the completion of the product masonry, a surface finishing, uneven, to be flat with the pressure plate, the gap should be cut to cut the larger ceramic fiber tile trim, so that the surface flat tight.
5. Each time the protective layer must be carried out in two rounds to ensure that the ceramic fiber blanket protective layer thickness and thickness uniformity.
6. Should meet the GB3003 ~ 3008-82 standard requirements.
