Edge Trimmer for 1.2-3.0 mm HiB Silicon Steel in Pickling Lines
HiB silicon steel is a high value grain oriented product where an edge crack ruins the coil and can break the strip downstream. This edge trimmer removes the defective edge on a pickling line running 1.2-3.0 mm material, keeping the width constant along the coil.
- Strip thickness 1.2-3.0 mm
- Built for HiB grain oriented silicon steel
- Double head cantilever rotary hybrid power shear
- Servo cylinder controlled width adjustment
Key Benefits
What trimming protects on a high value grade.
Strip Breaks Avoided
Edge cracks left in place cause the strip to break in follow up processes, which on silicon steel means losing a high value coil.
Width Held Constant
Trimming keeps the strip at the same width along its length, which downstream slitting and coating depend on.
Repeatable Width Settings
Servo cylinder control adjusts shearing width precisely, so the setting is repeatable between coils.
Where It Is Used
Line position.
- Pickling lines processing silicon steel
- Grain oriented electrical steel production
- Continuous production lines in metallurgical plants
- Preparation before cold rolling or coating
Who It Is For
- Electrical steel producers
- Pickling line operators
- Plants with edge crack losses on high value grades
- Project teams specifying trimming equipment
Problems It Solves
- Edge cracks causing downstream strip breaks
- Width variation along the coil
- Imprecise manual width setting
- Blade wear on hard silicon steel
Technical Features
How it cuts.
Two Blade Shearing
Two displacement and vertical circular blades are set to a defined gap and overlap, deforming the strip at contact until it fractures cleanly.
Double Head Cantilever Structure
A double head cantilever rotary hybrid power shear carries both trimming heads.
Blade Maintenance Features
Blades are double edged with end face grinding and hydraulic nut locking for quick change.
Specifications
Blade specification is matched to the grade being trimmed.

Manufacturing Process
Grade And Gauge Review
Material grade, thickness and trimmed width range define blade and drive specification.
Head And Frame Manufacture
Cantilever heads and frame are machined for blade alignment.
Blade Production
Circular blades are hardened and end face ground for the grade.
Assembly And Setting
Gap and overlap are set and the servo width control tested.
Quality Control
- Head alignment inspection
- Blade hardness and grinding record
- Gap and overlap setting verification
- Servo positioning accuracy test
Customization Options
- Trimmed width range for your coil programme
- Blade material and geometry for silicon steel
- Drive package to line speed
- Integration with scrap chopper and chute
Use Guide
- Set gap and overlap for the exact gauge
- Regrind blades on the end face before edge quality drops
- Verify hydraulic nut locking after blade changes
- Match trimmed width settings to downstream slitting plans
How It Compares
Against other trimming approaches.
| Trimming after cold rolling | Removing edge defects at the pickling line prevents breaks in the processes that follow. |
|---|---|
| Manual width adjustment | Servo cylinder control repeats the width setting exactly between coils. |
| General purpose trimmers | Blade specification is matched to hard HiB silicon steel rather than general carbon strip. |

Edge Trimmer for HiB Silicon Steel Pickling Lines FAQ
What thickness range does it cut?
1.2-3.0 mm HiB silicon steel on a continuous pickling line.
Why trim silicon steel at the pickling line?
Edge cracks from rolling will cause the strip to break in follow up processes. Trimming early protects a high value coil.
How is width adjusted?
Two oil cylinders drive the width adjustment with servo cylinder control for precision and repeatability.
How are the blades maintained?
Blades are double edged with end face grinding and hydraulic nut locking, so they can be turned and reground rather than replaced each time.
Can it handle other grades?
Yes, with blade specification matched to the material. Tell us the grades and gauges you run.
What do you need to quote?
Material grade, thickness and width range, trimmed width range, line speed and existing layout.
