Aogang Machinery Co., Ltd.
Tube Mill Rolls are the core forming tools in an ERW tube mill production line. Their performance directly affects tube forming accuracy, weld quality, surface finish, and overall production efficiency. High-quality rolls help improve product consistency, reduce downtime, and lower overall production costs.
Aogang Machinery specializes in the development and manufacturing of high-precision forged tube mill rolls. By utilizing premium tool steel, secondary forging technology, precision heat treatment, and CNC grinding processes, we provide durable, wear-resistant, and high-accuracy roll solutions for customers worldwide. Our rolls are widely used in ERW tube mills, square and rectangular tube production lines, and roll forming equipment, meeting the manufacturing requirements of round tubes, square tubes, rectangular tubes, and special-shaped profiles.
Aogang Tube Mill Rolls are manufactured from high-quality cold-work tool steels such as D2 (Cr12Mo1V1), D3 (Cr12), and Cr12MoV. These materials offer excellent wear resistance, compressive strength, and impact resistance. Customized alloy steel options are also available according to specific production requirements.
Compared with conventional cast rolls, Aogang rolls are produced from high-density forged blanks and undergo a secondary forging process. This process refines the grain structure, increases material density, eliminates internal defects, and significantly improves fatigue resistance and service life.
Advanced CNC turning and precision grinding equipment ensure excellent profile accuracy and dimensional consistency. The profile tolerance is controlled within 0.02 mm, while the surface roughness reaches Ra ≤ 0.4 μm, helping reduce tube surface scratches and improve product quality.
Through strictly controlled quenching and tempering processes, roll hardness is maintained at HRC 58–62. This provides an ideal balance between wear resistance and toughness, effectively preventing chipping, cracking, and abnormal wear.
Aogang rolls are designed with sufficient machining allowance and can typically be reground 3–5 times under normal operating conditions. After profile correction and regrinding, the rolls can restore excellent forming performance, significantly extending service life and reducing tooling costs.
In addition to roll manufacturing, Aogang provides complete pass design services. Customers only need to provide tube specifications and mill parameters, and our engineering team will develop optimized roll pass designs to solve forming instability, weld seam misalignment, and dimensional accuracy issues.
Aogang Tube Mill Rolls are widely used in structural steel tubes, furniture tubing, automotive components, mechanical tubing, oil and gas transmission pipes, cold-formed steel products, solar mounting systems, and various ERW tube mill production lines. They are suitable for producing round, square, rectangular, and special-shaped tubes.
With extensive experience in tube mill manufacturing, advanced forging technology, and professional pass design capabilities, Aogang delivers reliable and high-performance roll solutions for customers worldwide. Beyond supplying premium rolls, we provide comprehensive technical support, customized pass design, and engineering services to help customers improve tube quality, extend tooling life, reduce production costs, and increase overall productivity.
