Precautions for locking bricks in rotary kiln

Locking bricks refer to the bricks that are built last when building circular, semicircular or less than semicircular arches by means of arching, and are used to finally eliminate the gap between the bricks in the arch. The successful masonry of lock bricks will effectively prevent the loosening of refractory bricks and the lottery of bricks. Requirements are as follows:

1. When building the vault and the surrounding wall, when there are 5-6 bricks left in a circle, the refractory bricks should be dry-yarded repeatedly, and the combination of different specifications of bricks should be used to meet the requirements of wedge tightness. If it cannot meet the requirements, it is necessary to measure the size of the processed bricks carefully, and use the refractory bricks processed according to the size to dry-code again. The final space for masonry is exactly the space occupied by the three original bricks that have not been cut in thickness.

2. The brick surface of the processed brick shall not face the shell to prevent the refractory brick and the shell from being unable to be effectively attached.

3. The position of the lock brick should be 2 to 3 blocks away from the processed brick, and the lock brick operation cannot be carried out at the top of the arch. Locking bricks should be performed at equidistant positions on both sides of the vault.

4. The final use of the lock brick must be in the gap between the two original bricks that have not been cut in thickness, and the unprocessed original brick is used to perform the lock brick operation to ensure the strength of the lock brick and reduce the wedging of the lock brick. time friction.
