Abstract：The internal stress field in the coil is changed after coiling and coil discharge due to change of drum diameter，especially at the head of coil where more defects are observed.Based on measurement on site and tightness coefficient test, and by mechanical and thermal stress field calculation with differential method, the rule of stress distribution was obtained after coiling and coil discharge, so the effective countermeasures with theoretical consideration is given to eliminate defects,improve strip quality and qualification rate.
