Lightweight insulation bricks are generally used to keep warm and reduce heat loss, so they generally do not come into direct contact with flames, while refractory bricks can directly contact flames, and sometimes the temperature can reach more than 1,000 degrees, so the two have a great deal of difference. The big difference, today Xinhongji Refractory will give you a brief introduction to the difference between insulation bricks and refractory bricks.
1. Thermal insulation performance
The thermal conductivity of general insulation bricks is about 0.2-0.4 (average temperature 350±25°C) w/m.k, while the thermal conductivity of refractory bricks is above 1.0 (average temperature 350±25°C) w/m.k, so you can see The thermal insulation performance of the thermal insulation brick is much better than that of the refractory brick.
Generally speaking, the refractoriness of insulation bricks is much lower than that of refractory bricks. Usually, the refractoriness of insulation bricks is below 1400 degrees, while the refractoriness of refractory bricks can reach more than 1500 degrees.
The density of thermal insulation bricks is generally 0.8-1.0g/cm3, while the density of refractory bricks is basically above 2.0g/cm3, so refractory bricks under the same volume are heavier than thermal insulation bricks.
Insulation bricks are generally used for heat preservation, heat insulation, energy saving, and reduction of heat energy waste. It can reduce the weight of the kiln, reduce the wall of the kiln, change the structure of the kiln, increase the heating rate, reduce energy consumption, improve working conditions, and increase work efficiency. Refractory bricks have high mechanical strength, long service life, good chemical stability, no chemical reaction with materials, and good high-temperature resistance. The maximum heat resistance temperature can reach 1900 °C. It is especially suitable for high and low-temperature shift furnaces, reforming furnaces, hydrogenation converters, desulfurization tanks, and methanation furnaces in chemical fertilizer plants. It plays the role of dispersing gas and liquid and supporting, covering, and protecting catalysts. It can also be used in hot blast stoves and heating transformation equipment in the steel industry.
There is a big difference between thermal insulation bricks and refractory bricks, and the parts used are also different, so when we choose, we must choose according to the scene and location of use.
