Cause of refractory brick appear crack

Refractory brick is refractory material with certain shape and size, according to the material is usually divided into high aluminum brick and clay brick, lightweight refractory brick.Refractory brickis mainly used for lining, stoves and other parts of the chimney. Standard refractory brick is also known as the T-3 refractory brick is a brick, the most widely used, then the brick may appear crack phenomenon in the use process, crack damage occurred mainly in the baking stage. Baking time, have a variety of stresses, if the stress exceeds the limit strength of refractory allowed, will appear crack.

Yilong refractory company for your detailed account of the factors that lead to the crack which appeared firebrick:

(1) Temperature differential stress:

When baking kiln, firebrick inside in a certain temperature difference, resulting in stress.

(2) Crystal transition stress:

Refractory bricks in the heating process can occur crystal transition, changes in crystalline form if excessive, stress is too large, and cracking will produce the refractory bricks;

(3) Mechanical stress:

The role of non-elastic deformation produced in the mechanical load on the Ambassador firebrick caused damage.
