Insulation Fire Brick Details
Product Details
The operating temperature range of Insulation Fire Brick is 900℃ to 1600℃. The product is made of high-quality and ultra-pure raw materials and is strictly filled according to grade. It is mainly used for thermal insulation of thermal equipment and industrial kilns. It can be used in areas where there is no strong high-temperature molten material erosion and erosion. The product can reduce the basic cost, and has good machinability and easy construction. Using this product in construction can reduce the weight of the building and greatly reduce the overall cost of the building.
Advantages
1. Economic: Insulation Fire Brick can reduce the foundation cost, reduce the cross-section of the frame, save reinforced concrete, and can greatly save the overall cost of the building. Compared with solid clay bricks, the design and use of light bricks can reduce the total cost by more than 5%.
2. Practicability: The use of lightweight bricks can increase the area of use. At the same time, due to the thermal insulation of the aerated concrete, the thermal insulation effect is good. In hot summer days, the indoor temperature is 2-3°C lower than solid clay bricks. energy consumption.
3. Constructability: Lightweight bricks have good machinability, and construction is convenient and simple. Due to its large size and light weight, it can reduce labor intensity, improve construction efficiency, and shorten the construction period.
Features
Lower thermal conductivity
Lower bulk density
Light weight character
Lower creep rate in high temp
Good thermal shock resistance performance
Higher temperate resistant with good refractoriness
Applications
Insulation Fire Brick can be applied to the refractory lining of hot surfaces or the back insulation of other refractory materials; it can also be used as the refractory lining or insulation materials of petroleum or chemical industry furnaces, such as ethylene pyrolysis furnaces, tube furnaces, and synthetic ammonia Furnace, gas generator and high temperature shuttle kiln etc.
Specifications
Alumina contents range from 40% to 80%
Widely used throughout metallurgical industry

Semi-silica brick refers to an aluminum-silicon refractory product with a SiO2 content of greater than 65% and an Al2O3 content of 15% to 30%. They generally use clay containing quartz impurities or native kaolin refractory clay or tailings and pyroph...
The Al2O3 content of anchor bricks is above 55%, and some users require that the alumina content reach 75%, and the load softening temperature of 75% bricks reaches 1550C. However, in actual use, anchor bricks with high aluminum content cannot be enough. The key is Flexibility is the most important t...
