Refractory bricks are used as materials in many construction projects. Have you ever understood them? If you don't understand them, it doesn't matter, the Golden Triangle refractory manufacturers will answer you. The refractory bricks are divided into fixed and unshaped refractory bricks in the big classification. Classification.
Refractory bricks are widely used more than clay and high-aluminum insulation refractory bricks, and account for a small proportion of the total output of thermal insulation lining. In the production process of refractory bricks, the physical and chemical changes generally do not reach the equilibrium state at the firing temperature. There are also refractory bricks that are not sufficiently burnt. Therefore, in order to maintain the integrity and stability of the furnace wall during the action of the rotary kiln, in order to maintain the integrity and stability of the furnace wall, every 5 to 8 layers are used, where the height of the bricklaying layer is the same. The masonry method of pulling the inner and outer walls to each other, that is, inserting one half of the refractory brick into another brick layer or fixing it with a metal anchor.
The main advantages of refractory bricks are as follows:
First, the load softens the temperature. This feature is the most critical parameter of refractory bricks. It can be said that it directly determines the ability to withstand high temperatures and the strength.
Second, the chemical composition. This feature of refractory bricks is mainly used to determine the overall properties of the material and the associated quality.
Third, the ability to resist thermal shock, this feature is mainly to help the refractory bricks in the temperature rise and change sharply, without damage, damage and so on.
Fourth, the bulk density. For the bulk density of refractory bricks, the higher the density of the unit, the higher the compactness of the refractory brick and the better the strength. In addition, for the bulk density of refractory bricks, the relevant manufacturers must strictly require the venting of the product as a whole.
Fifth, the compressive and flexural strength. In the operation work, refractory bricks not only have to withstand normal temperature, but also need to face some shear pressure frequently. At this time, the strength of the flexural and compressive pressures needs to be very high.
