The main function of the industrial chimney is to remove the waste smoke from the kiln, and at the same time, it also prevents the flame from burning in the furnace. When the temperature of the waste gas entering the chimney is high, the inner wall is generally built with a working layer. If the flue gas is acidic, acid refractory bricks are built, and lightweight refractory castables are also used. The chimney is an indispensable facility in industrial production. It undertakes the important task of discharging waste gas. It not only ensures the normal operation of the industry, but also affects the safety of production operations. Therefore, the construction of the chimney is very important. In addition to being able to It can withstand high temperatures and resist flue gas erosion in harsh working environments. In order to meet such a working environment, it is very important to build chimney refractory fire bricks for chimneys.
Since chimney refractory bricks are very important for the construction of chimneys, we must pay attention to some things when purchasing. First of all, when purchasing, we must choose according to the environment used. We must look at the physical and chemical indicators of chimney refractory fire bricks, acid resistance A series of physical and chemical indicators such as chemical resistance, alkali resistance and refractory temperature. In fact, when purchasing, we must examine the manufacturer's scale, production technology, product standards, after-sales service and other factors, so that we can purchase good quality chimney refractory brick.
The composition of chimney refractory bricks is mainly made of alumina, silica and other materials with high melting points. These materials are combined with binders, die-cast with high-pressure machinery, and finally fired in a high-temperature environment. It can make the chimney have high fire resistance. At the same time, the chimney refractory fire bricks will be calcined at high temperature during the production process to make it denser and have good thermal insulation effect, thereby protecting the internal structure of the chimney from high temperatures. Heat damage.
Fire brick is a kind of brick that can withstand high temperatures. It not only needs to resist the high temperature of smoke, but also needs to maintain stable physical and chemical properties at extremely high temperatures. It is not easy to be burned, corroded, or cracked. These advantages are This makes it outstanding in chimney construction, but ordinary bricks are difficult to meet such working conditions. Such high temperatures cannot be tolerated by traditional bricks. Thermal expansion and contraction will cause the bricks to crack and even cause the chimney to collapse.
The quality of chimney brickwork and safety construction requirements are the key to ensuring the safety and service life of the chimney. During the bricklaying process, the relevant requirements should be strictly followed to ensure the quality of the bricklaying and improve the safety performance of the chimney. In addition, construction workers must have relevant skills and experience, and safety education and training should be strengthened to enhance the safety awareness and skills of construction workers.
Therefore, when using refractory bricks in chimneys, special attention should be paid to the high temperature resistance, corrosion resistance, and thermal conductivity of the refractory fire bricks. To ensure the safety and durability of the chimney.
