This test record documents a 25 mm S355J0 hot-rolled coil processed through decoiling, leveling, and cut-to-length operations.
Test objective
The objective was to evaluate whether heavy-gauge material could be fed, leveled, cut, and stacked while maintaining usable finished-plate condition.
Evaluation points
- Coil loading and decoiling stability
- Material feeding through the leveling section
- Cut-to-length control and dimensional consistency
- Finished-plate flatness and diagonal accuracy
- Stacking condition after cutting
Practical takeaway
A published thickness range alone does not guarantee a successful result. Coil shape, hardness, residual stress, width, and weight must be reviewed together. RUIJI evaluates those factors before confirming a processing plan.
