EMA Extruded Pipe Ovality Out of Standard
문제 현상
EMA extruded pipe ovality >1.05, exceeding the 1.02 standard requirement
원인 분석
Pipe cooling uneven, single-side cooling; sizing sleeve design unreasonable; haul-off clamping force uneven, causing the pipe to deform under pressure
해결 방법
1) Adopt annular spray cooling to ensure uniform temperature reduction; 2) Optimize the sizing sleeve inner diameter and taper design; 3) Multi-caterpillar uniform clamping haul-off; 4) Increase the vacuum sizing section length to ensure full sizing
핵심 요약
Ovality is caused by uneven cooling and clamping; annular cooling and uniform haul-off are key
