The kiln sometimes deforms the equipment during the firing process for the following reasons:

1, the surface temperature is high, the bottom temperature is low, the brick is easy to "concave" and tilt angle.

2, the surface temperature is low, the bottom temperature is high, the brick is easy to "arch" and corner hook.

3. The front temperature is insufficient (the temperature is too low, the area is short), and the brick is easy to arch or concave.

4. The medium temperature stage is too short, the temperature rises too fast, and the brick is easy to "wave-shaped" deformation.

5, medium temperature is too high, high temperature is too high, brick is easy to fire deformation.

6. The front temperature and medium temperature are insufficient, and the surface temperature of the high temperature section is too high, which is easy to cause the front angle to become warped and the back angle to be deformed.

7. For the last 1~3 groups of bottom guns at the end of the high temperature section, the bottom temperature is too high, and the brick is easy to deform under the corner hook.

8. The upper and lower burner nozzles are unbalanced, and the bricks are easy to deform, or concave or arch.

9. If the fire barrier wall is too high and the fire barrier plate is too low, it is easy to cause local high temperature and the brick is easy to warp and deform.

10. If the smoke exhaust fan is turned on too much, the kiln will have a large negative pressure and the bricks will arch easily. On the contrary, if the smoke exhaust fan is turned on too little, the kiln will have a large positive pressure and the bricks will tilt easily.

11. If the heat extraction fan is turned on too much, the surface temperature of the rear section of the firing belt is high, and the brick is easy to be concave or tilted. On the contrary, when the heat extraction fan is turned on, the surface temperature of the rear section of the firing zone is low, and the bricks are easy to arch or bend down at corners.

12. The quenching wind of the upper quenching pipe blows in the direction of the kiln head, and the bricks are easy to arch; Blowing in the direction of the kiln tail, the bricks are easy to dent.

13. The bottom wind of the sudden cold is too large, and the bricks are easy to dent. On the contrary, if the wind is too strong on the cold side, the bricks will arch easily.

14. The interval between bricks is too large, bricks are easy to dent, the interval is too dense, and bricks are easy to arch.

The above is an analysis of the causes of equipment deformation in kiln firing.
