- Abstract:
- The rotary kiln is one of the key equipment of the cement production system, and its service status directly affects the output and quality of cement. Aiming at the problem of cracking of the cylinder weld of a cement rotary kiln along the cylinder axis, the mechanical analysis of the wheel belt and the cylinder shows that the stress causing the cracking of the cylinder weld at the cushion plate mainly includes bending stress, temperature stress, residual stress, etc. Combined with fracture mechanics and elastoplastic mechanics, the mechanical model of cylinder weld crack was constructed, the fracture criterion of cylinder weld was established according to the stress strength factor, and the safety assessment of the crack was carried out, and the accuracy of the model and assessment was confirmed by on-site crack statistics, and the critical size of the crack was 141 mm.
