- Q: What's the difference between high alumina refractory bricks and high alumina refractory bricks?
- The chemical pH value of high alumina refractory brick belongs to neutral and alkaline refractory brick, and clay refractory brick belongs to neutral and acid refractory 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: How to reduce porosity of high alumina brick
- High alumina brick used as refractory products in refractory material, has a great application in masonry kilns, insiders pointed out that the quality of high alumina brick general porosity and it has a great relationship! So, how to reduce the porosity of high alumina brick rate is very important!
- Q: What are the specifications for bricks?
- In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.
- Q: What are ordinary bricks, refractory bricks, hollow bricks?
- Referred to as refractory brick. Refractory wood made from refractory clay or other refractory material
- 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 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: What is the apparent porosity of high alumina brick?
- Total porosity is porosity refers to the total volume of sample porosity in the percentage of total volume of samples. Apparent porosity refers to the percentage of the total volume of openings, pores, and total specimens in the sample.
- Q: How are the grades of high alumina bricks differentiated?
- If the content of Al2O3 is higher than 90%, it is called corundum brick. Because of the different resources, the standards of different countries are not exactly the sameFor example, European countries limit the content of Al2O3 for high alumina refractory materials at 42%.
- Q: Which thermal shock stability of clay brick and high alumina brick is good?
- High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.
