- Tandem Warm Rolling for Grain-Oriented Steel Inter-Pass Aging
Extending the pass line in tandem warm rolling increases inter-pass aging time, improving recrystallization texture and magnetic properties.
- Warm Tandem Rolling for Grain-Oriented Steel Texture Control
Extended pass lines in warm tandem rolling give carbon and nitrogen more inter-pass aging time, improving grain-oriented steel texture and iron loss.
- Cold-Rolled Silicon Steel Strip Joints Heated to Prevent Fracture
Heating the welded strip joint to 50°C or higher before cold rolling suppresses fracture and keeps silicon steel strip production stable.
- Heated Strip Joint Rolling for Fracture-Resistant Silicon Steel
Preheating the welded strip joint before cold rolling suppresses fractures in high-silicon steel and keeps the rolling line stable.
- Tandem Warm Rolling Pass-Line Extension for Grain-Oriented Steel
Extending the tandem mill pass line at 150-280°C increases inter-pass aging time, improving grain-oriented steel texture and iron loss.
- Coil Box Roller Wear Balancing Through Independent Drive Control
Independent roller drives and wear sensing rebalance speed, torque, and position to even coil box roller wear and cut downtime.
- Negative Pressure Roll Loop Take-Up for Damage-Free Slitter Lines
A negative pressure roll with a non-woven outer layer absorbs long slitter-line loops while limiting metal strip surface damage.
- Retractable Transfer Table Looping for Steel Entry
Merging looping and transfer functions into a single retractable unit eliminates separate equipment, cutting cycle time by five seconds per coil.
