Q: What are the high aluminum bricks made of?: It's OK to use corundum bricks and alumina hollow ball bricks to build a furnace,

Q: What refractory material does cupola lining use?: It's made of high quality refractory material: 1770 ~ 2000 centigrade.

Q: What are the requirements for Rubble backfill height?: Backfill should be filled with large stones, big face, small face upward, the decoration is stable, and then use small stones leveling, the gap between the stones can be swept into the slag, gravel, so that the gap filled.

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?: Quality requirements for aluminium bricks of different grade. 2, high aluminum powder and high alumina aggregate and other materials of reasonable proportion, to reach the production requirements.

Q: What is the content of free silica in the refractory bricks of high alumina bricks?: In the meantime, the free silica content of silicon brick is as high as 90% above. Therefore, the most serious damage is silicon brick, followed by clay brick, high alumina brick, magnesia brick and so on.

Q: Which is faster for heat transfer between corundum bricks and high alumina bricks?: There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color.

Q: How much is one ton / ton of high alumina refractory brick?: The price of high alumina refractory bricks is not equal, according to the quality index of GB2988-2012

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: 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.
