Section Rolls
What Are Section Rolls?
Section Rolls are specialized rolling mill rolls designed for producing structural steel profiles such as I-beams, H-beams, channels, angles, and other long products. These rolls play a crucial role in shaping and finishing steel sections with high dimensional accuracy and excellent surface quality.
Depending on the rolling stage, Section Rolls can be categorized into:
- Roughing Section Rolls – handle the initial breakdown of billets into section shapes.
- Intermediate Section Rolls – refine dimensions and form profiles more accurately.
- Finishing Section Rolls – provide the final shape, ensuring smooth surfaces and tight tolerances.
Material and Manufacturing
Section Rolls are commonly manufactured from forged steel, cast steel, alloy cast iron, or high chromium materials, depending on rolling requirements. Advanced heat treatment processes, such as quenching and tempering, ensure optimal hardness, wear resistance, and toughness.
Applications of Section Rolls
- Steel Structures: Beams, columns, channels for construction.
- Automotive Industry: Chassis, axles, and structural components.
- Railway Industry: Rails, sleepers, and supporting sections.
- Shipbuilding: Structural frames and hull reinforcements.
Section Rolls vs. Other Rolling Mill Rolls
While Section Rolls are designed for shaping structural steel profiles, other types of rolls serve different applications.
| Type of Rolls | Main Application | Typical Products | Key Features |
|---|---|---|---|
| Section Rolls | Rolling structural sections | I-beams, H-beams, channels, angles | High dimensional accuracy, handles large cross-sections |
| Strip Rolls | Rolling flat steel strips and coils | Hot-rolled strip, cold-rolled strip, sheet steel | Produces thin, wide products with smooth surfaces |
| Bar Rolls | Rolling bars and rods | Round bars, square bars, hexagonal bars | Precision shaping for construction and machinery use |
| Wire Rolls | Rolling wire rods | Wire rod coils for fasteners, springs, welding wire | High-speed rolling, fine diameter control |
| Pipe Rolls | Rolling hollow sections and tubes | Seamless pipes, welded pipes, hollow profiles | Specialized design for tubular shapes |
Key Insight:
- Section Rolls focus on structural integrity for construction and heavy industry.
- Strip Rolls & Bar Rolls focus on dimension and surface quality for general manufacturing.
- Wire Rolls emphasize high-speed production for small diameters.
- Pipe Rolls are engineered for hollow profiles in oil, gas, and fluid transport industries.
Key Advantages
- High wear resistance for long service life
- Excellent dimensional accuracy for structural profiles
- Customizable materials to suit different rolling mill conditions
- Cost-effective solutions for large-scale steel production
