Type
Breakdown Rolls
Function: To initially bend the steel strip and complete the basic deformation of the sheet
Characteristics: High load, rapid wear, determining the stability of the forming process
Finishing Rolls
Function: To shape the tube billet into a shape close to the finished product
Characteristics: High precision requirements, ensuring the flatness of the welding joint
Sizing Rolls
Function: Precisely control the outer diameter, roundness, and straightness of the pipe
Characteristics: High dimensional accuracy, reducing forming errors
Straightening Rolls
Function: Correct the bending and ensure the straightness of the pipe
Characteristics: Mostly used for high-precision round pipes and square pipes
Grade
- GCr15 - Higher hardness, wear-resisting
- Cr12MoV - Higher hardness, wear-resisting, used for Sizing Rolls
- 9Cr2Mo - Stretched and impact-resistant, suitable for thick wall pipes
- H13 - Heat-resistant, used in high-temperature engineering
Application
- Working principle: Forging → Heat treatment → Quenching → Fine grinding → Polishing / Chrome plating
- Round pipes: Water pipes, gas pipes, fluid pipes, scaffolding pipes
- Square and rectangular pipes: Steel structures
- Galvanized pipes: Outdoor buildings, areas requiring anti-corrosion
- Special-shaped pipes: conical pipes
- Industrial pipes: Thin-walled precision pipes
