Flat Steel Longitudinal Shear Blade

The Flat Steel Longitudinal Shear Blade is a precision circular cutting tool installed on longitudinal slitting machine shafts for continuous slitting of metal coils into flat steel strips. Also known as rotary shear blade or slitting circular knife, it is a critical component in modern metal processing lines where cutting precision, burr control, and blade durability directly affect production efficiency.

As a professional precision blade manufacturer, Xinzhe Blades designs and produces Flat Steel Longitudinal Shear Blade solutions using advanced CNC machining, integrated heat treatment, and precision grinding technology. Our products are widely selected by steel processing plants, coil service centers, and OEM machinery manufacturers requiring stable cutting performance.

Product Structure

The complete Flat Steel Longitudinal Shear Blade assembly includes:

Blade Disc

The primary cutting element with precision-ground edges for smooth longitudinal slitting.

Separator Discs

Control strip spacing and prevent strip surface collision.

Spacer Sleeves

Maintain blade alignment and ensure consistent cutting clearance.

These components work together in matched upper and lower rotating pairs to achieve continuous, high-speed cutting.

Technical Specifications

Material Selection

Different processing conditions require different material grades. Xinzhe Blades offers:

Performance Advantages

High Cutting Precision

Precision CNC grinding ensures smooth cutting edges with minimal burr formation.

Extended Service Life

Forged alloy steel combined with quenching, tempering, and cryogenic treatment improves wear resistance and prevents edge chipping.

Stable High-Speed Operation

Static balancing eliminates eccentric rotation, reducing vibration during continuous slitting.

Strong Compatibility

Suitable for carbon steel, stainless steel, alloy steel, and galvanized steel coil processing.

Reduced Maintenance Cost

Longer sharpening intervals significantly reduce production downtime.

Typical Applications

The Flat Steel Longitudinal Shear Blade is widely used in:

Steel structure manufacturing

Welded tube blank processing

Elevator guide rail production

Bridge component fabrication

Photovoltaic grounding flat steel production

Industrial support bracket manufacturing

Frequently Asked Questions

Q1: How do I choose the right Flat Steel Longitudinal Shear Blade material?

For standard carbon steel, 6CrW2Si is cost-effective. For stainless steel and abrasive materials, Cr12MoV or SKD-11 provides better wear resistance.

Q2: What affects blade service life?

Blade life depends on cutting material hardness, clearance adjustment, lubrication conditions, and maintenance frequency.

Q3: Can Xinzhe Blades provide custom dimensions?

Yes. We manufacture according to customer drawings, machine specifications, and slitting requirements.
