Do you know the precautions for these fire bricks?

 
The flue is one of the important parts of the kiln. The flue refractory bricks need to be both heat-resistant and high-temperature resistant.

Therefore, this part is usually used in combination with refractory materials and thermal insulation materials. Among them, clay bricks or high-alumina bricks can be used as refractory materials. Clay bricks for flue refers to clay products made of aluminum silicate with an Al2O3 content of 30% to 40%. It is made of 50% soft clay and 50% hard clay clinker. A certain particle size requires batching. After molding and drying, it is fired at a high temperature of 1300 to 1400 ° C. It is a weakly acidic refractory product, which can resist the erosion of acidic slag and acid gases, and has a slightly lower resistance to alkaline substances. , With good thermal performance, resistance to rapid cold and heat.
 

Precautions for the use of flue refractory bricks
Matters to be paid attention to during masonry. First, the profiled clay refractory bricks, ordinary clay refractory bricks and cement expanded perlite bricks for flue should be inspected and accepted piece by piece, and shall be accompanied by a factory certificate and prescribed tests. single. Secondly, clay, cement and other powders used for masonry flues should be stored in covered warehouses and must not be immersed in rain. Clay refractory bricks can be stored in the open air, but should be covered with rain and waterproof measures.
 
Third, refractory bricks should be arranged in accordance with the construction order, and stacked on top of large, medium and small tolerances. A signboard should be set up, and the number, quantity and tolerance of the brick stack should be indicated on the label. Clay clinker and bonded clay should be connected with varieties and grades. Strict separation to prevent confusion. Therefore, pay attention to these matters when using refractory bricks in the flue to ensure the reasonable and proper use of refractory bricks.
