The cause of porcelain pipe fracture

What are the causes of porcelain tube fracture? Below are several reasons for small make up, I hope to help daily maintenance of porcelain tube.

(1) the quality of porcelain tube is not in conformity with the requirements of firing speed and temperature.

(2) aging of porcelain tubes.

(3) porcelain tubes are not at the same horizontal plane, and individual porcelain tubes are overloaded.

(4) kiln plates and products are overweight.

(5) there are foreign matters such as stuck to kiln column between porcelain tubes.

(6) the speed is too fast and the torque is too large.

(7) the forward direction is subject to resistance, such as the front speed is slower than the rear speed, resulting in excessive resistance and torque.

(8) the porcelain tube is separated from the clamp for a long time, without rotation and deformation under pressure.

(9) when the kiln is stopped, the transmission motor closes too early, and the kiln plate is not removed, causing the porcelain pipe to stop rotating under high temperature and bend under pressure.

(10) the porcelain pipe was shot by the nozzle for a long time, and the local high temperature deformation.

(11) long-term contact wear of porcelain pipe and kiln brick, etc.
