Pretreatment and Annealing management
for steel wire
|Process||Pickling ( HCL and H2SO4 )
→ Heat treatment ( 800℃ x 10hours )
・Product ID management
・Eliminate identification errors and lost coils
・Reduce of Labor cost.
Previous management method
Normal PET tag was used.
Point of Problem
- PET tag doesn't have enough heat resistance, so it has to
be detached before heating process.
- Mixed steel events and incorrect identification occur when PET tag is
reattached after heat treatment.
Solution by HEATPROOF
- Provide a barcode tag which can survive all processes.
- Eliminate identification errors caused by attaching the wrong tag to wire coils
