The difference between dense high aluminum bricks and ordinary aluminum bricks is low pores, more dense, longer use cycle, and stronger erosion resistance.
1. The difference between production technology
The production process of dense high aluminum bricks is different from the production process of ordinary high aluminum bricks. In the production process of ordinary high aluminum bricks and dense aluminum bricks, the production processes of selection, crushing, stirring, molding, and drying are the same, but There are differences in the process ratio, and the dense high aluminum bricks should add a certain percentage of coke gemstone or blue crystal than ordinary refractory bricks.
The blue spry has a high expansion coefficient. In the process ratio of high aluminum bricks, the size of the particles is very important. The particle expansion coefficient greater than 3mm is not controlled. Generally, the particles must be controlled when the amount is controlled. When adding Coke gemstones, it is also controlling the impurities of coke gemstones. Otherwise, the surface of fire -resistant bricks is rough or difficult to control.
2. The difference between dense bricks and ordinary aluminum bricks and surfaces
There are also differences between dense bricks and ordinary aluminum bricks and surfaces. The general high aluminum bricks are yellow and white, and the color of the dense high aluminum brick is reddish. The pore rate is low. The color of high aluminum bricks looks good, but the pore rate will be relatively high.
3. The difference between the price of dense bricks and high aluminum bricks
The prices of dense bricks and high aluminum bricks are also different. The price of ordinary bricks is hundreds of hundreds or thousands of yuan lower than the price of dense bricks, because the additional substrate and sintering temperature are different, resulting in increasing costs. Generally, high aluminum bricks are burned into less swelling. When controlling tiles, the firing temperature will be relatively high.
High aluminum brick in the corrosion resistance, not as dense high aluminum brick, dense brick because of low porosity, acid erosion resistance than ordinary high aluminum brick will be one to two times higher, the service life will be one to two times higher than ordinary high aluminum brick.
Therefore, there is a difference between dense high-aluminum bricks and ordinary high-aluminum bricks, which are produced on demand according to different situations of kiln lining. In the use of high-aluminum bricks will be more than dense bricks, dense bricks belong to high-aluminum series of high-grade materials, and high-aluminum bricks are divided into different grades according to aluminum content and volume density, dense bricks are divided into different grades according to the porosity level.
