High Output 90m/min Tube Mill Machine ZY16 Φ8-18mm HF Welded Steel Pipe

Problem When a mill is pushed to high speed, the strip becomes unstable. Coil changes stop the line, tension surges pull the weld seam off-center, and forming rollers heat up and shift, causing scrap and downtime that erase the speed gain. Cause Speed amplifies every upstream variation. Without a buffer store, the line must slow for each coil change; without stable tension, the weld gap oscillates at speed; and without heat management, roller geometry drifts under friction
