What are the reasons for the cracks in the refractory bricks? I believe many people are more concerned about this problem. The following refractory brick manufacturers tell you why the refractory brick will be cracked:
1. Crystal transformation stress: The refractory brick will undergo crystal transformation during the heating process. If the crystal form changes too fast and the generated stress is too large, the brick will be cracked.
2. Mechanical stress: excessive mechanical load on the refractory brick causes the brick to undergo inelastic deformation and cause damage;
3. Temperature difference stress: When the kiln is baked, a certain temperature difference occurs inside the refractory brick, and stress is generated, resulting in cracking.
