The Main Differences of Refractory Bricks and Thermal Insulation Refractory Bricks

Thermal Insulation Refractory Bricks and refractory bricks are refractory materials. And the insulation refractory materials commonly used in furnaces and various high-temperature equipment. Although they are refractory bricks, their performance and use are completely different. Today RS refractory factory will introduce the main functions and differences between the two.

      The main function of thermal insulation refractory bricks are to maintain heat and reduce heat loss. Generally, thermal insulating fire bricks do not directly contact the flame, while refractory bricks generally directly contact the flame. Refractory bricks are mainly used to withstand flames. Generally divided into two types, namely, unshaped refractories and shaped refractories.

      Shaped refractory materials, generally made of refractory bricks, have standard rules for their shapes, and can also be temporarily processed when required for construction and cutting.

      The Main Differences of Refractory Bricks and Thermal Insulation Refractory Bricks:

      1.Insulation performance:
      The thermal conductivity of thermal insulation bricks is generally 0.2-0.4 (average temperature 350 ± 25 ° C) w / mk, while the thermal conductivity of refractory bricks is more than 1.0 (average temperature 350 ± 25 ° C) w / mk, which can be obtained The insulation performance is much better than that of refractory bricks.

      2.Fire resistance:
      The fire resistance of insulation brick is generally below 1400 degrees, while the fire resistance of refractory bricks is above 1400 degrees.

      3.Density:
      Insulation bricks are generally lightweight insulation materials, the density is generally 0.8-1.0g / cm3 and the density of refractory bricks is basically above 2.0g / cm3.

      In general, 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 conversion furnaces, conversion furnaces, hydrogenation converters, desulfurization tanks and methanation furnaces in 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 conversion equipment in the steel industry.

      Refractory bricks have the advantages of high density, high strength, wear resistance, good corrosion resistance, small thermal expansion coefficient, high grinding efficiency, low noise, long service life, and no contamination of materials. It is a high-quality grinding medium suitable for various grinding machines.

      Refractory bricks are very different from thermal insulation bricks, and their use environment, scope and role are different. Different materials will be used in different positions. When choosing refractory materials, we must decide which refractory material is suitable for our own use according to our actual situation.
