The Meaning of Low Creep and Spalling Resistance in Refractory Bricks

2024-01-30 13:55:12

Low creep and resistance to spalling are two important performance indicators of refractory bricks, and their meanings are as follows:

Low Creep: Creep refers to the continuous deformation of materials caused by stress under high temperatures for a long time. In a high-temperature environment, refractory bricks will be affected by thermal stress, and creep is the continuous deformation of the brick material under the action of this stress. Low creep means that refractory bricks can maintain small deformation when used at high temperatures for a long time, reducing adverse effects on the kiln structure.

Spall Resistance: Spall resistance refers to the ability of refractory bricks to resist peeling or chipping caused by thermal shock at high temperatures. Inside the kiln, due to high temperatures and thermal cycles, refractory bricks will withstand stress caused by thermal expansion and contraction and are prone to peeling or chipping. Refractory bricks with good spalling resistance can effectively resist such spalling and chipping, maintaining the integrity and stability of the lining.

Low creep and resistance to spalling are important performance indicators of refractory bricks when used for a long time in high-temperature environments. Good refractory bricks should have low creep and good spalling resistance to ensure the stability of the kiln lining, extend its service life, and reduce the frequency of repairs and replacements. These performance indicators are usually related to the material composition, structural design, sintering process, and other factors of refractory bricks. Choosing refractory bricks with low creep and spalling resistance can improve the reliability and efficiency of your kiln.
