Out-of-Roundness of CMC Extruded Pipe Exceeding Standard
Fenómeno del problema
Out-of-roundness of CMC extruded pipe >1.05 exceeds the 1.02 standard requirement
Análisis de la causa
Pipe cooling is uneven, single-sided cooling; sizing sleeve design is unreasonable; uneven haul-off clamping force causes the pipe to deform under pressure
Solución
1)Adopt annular spray cooling to ensure uniform temperature reduction; 2)Optimize sizing sleeve inner diameter and taper design; 3)Multi-caterpillar uniform clamping haul-off; 4)Increase vacuum sizing section length to ensure full sizing
Conclusión clave
Out-of-roundness is caused by uneven cooling and clamping; annular cooling and uniform haul-off are the key
