The relation between bulk density and price of third level high aluminum brick

High aluminum bricks belong to the neutral series of firebricks, because of different aluminum content, there are different levels, but at present, the severe situation of the market, such as third level high aluminum bricks, for different bulk density, the application and price have big difference.

Third level high aluminum bricks aluminum content in 55%, it will not compared to the internal quality of the bricks if only focus on the price when purchasing, because if the bulk density is different, the raw materials and processes are not same, the higher the bulk density, the internal quality of the brick will be better, also lower porosity and higher strength.

Different bulk density of third level high aluminum bricks prices are also different, each increase of 0.01 bulk density, the price will increase by more than a few hundred yuan, if the soft load is increased, the price will increase by several hundred yuan, or even thousands of yuan, because what heavy softening temperature and raw materials, sintering temperature, process ratio has a great relationship, the more demanding, the higher the cost of raw materials, the price will also increase.

At present, due to the price war, the three-level brick is only said to compare the aluminum content is more, other indicators are based on different lining and temperature and then volume density, load softening temperature, and then according to different requirements, calculate different prices. If only the aluminum content, the lowest price, and even the aluminum content of clay bricks can meet the requirements of third level high aluminum bricks, but if the demand for physical indicators is high, the price alone will lose the meaning of the quality requirements.

From the actual words of the three-level high aluminum brick manufacturers and market demand, only the use of aluminum content is still a relatively large proportion, and the quality requirements for the full index are rare. In any case, quality and price complement each other, low price is sure to have low intrinsic quality, and the volume density will be reduced.

Therefore, the three-level high aluminum brick can not only compare the price, we must look at the actual use requirements, at the same time, we must notice the main indicators of bulk density, porosity, load softening temperature, and then the comparing will be reasonable.
