Refractory bricks have the advantages of high strength, easy construction, and various laying methods, and their production costs are not high. The raw materials are basically clay and the like, which reduces the construction cost of the construction unit to a certain extent. We often use different parameters to measure the quality of bricks, and the compressive strength is one of them. So in order to improve the quality of bricks, is there any way to improve the compressive strength of bricks?
1. It is recommended to use low-temperature long-term burning.
2. Properly extend the holding time: the same raw material, the same brick machine, the same heating and cooling speed, the sintering temperature is 900 ℃, the holding time is different, the compressive strength of the sintered brick will be different, the appropriate holding time, It is beneficial to improve the compressive strength and quality of sintered bricks.
3. Properly increase the temperature of sintered refractory bricks: Tests have shown that the same raw materials and bricks produced by the same brick machine have different firing temperatures and different strengths. The test results show that the compressive strength of bricks increases with the increase of the firing temperature of the tunnel kiln.
4. The pressure of the brick machine is increased and the density is increased. Only by increasing the density of the bricks can high-strength sintered bricks be fired. For bricks with a molding pressure of 2.2-2.3MPa, the compressive strength of the fired brick is generally 13.9-15MPa, and for the bricks with a molding pressure of 3MPa, the compressive strength of the fired brick can easily reach 20MPa.
If you want to improve the compressive strength of refractory bricks, you may wish to try the above methods. Improving its compressive strength will reduce the possibility of cracks and allow it to be used in different pressure environments. Improve its environmental adaptability.
