High frequency steel tube mill is one of manufacturing machines, producing steel tubes and pipes throught roll profies. By changing the roll profies, steel pipes of different sizes can be produced. Tube mill roll profiles directly impacts the quality, shape, and dimensions of the tubes produced.

What is the Tube Mill Roll Profile?

The roll profiles are installed on steel tube mill machine to make steel tubes or pipes. These roll profiles are specifically designed to gradually form flat metal strips into round, square, or rectangular tubes through a series of precise stages. The tube mill roll profile with high precision, high durability and long serive life.

Production Process of Roll Profiles

Material for roll profiles - roughing process - drilling hole - CNC fine finshing - polishing - typing code - heat treatment - grinding inside hole - drilling keyslot - drilling hole for bearing - finished product inspecion

Material of Roll Profiles:

The type of material : Cr12Mov, SKD11, D2, SKD61.

Tube/Pipe Dimensions:

Round pipe: 4.8mm to 630mm; Square pipe: F10x10mm to 500x500mm; Rectangle pipe: F10x20mm to 300x600mm.

Design of Roll Profiles:

Customize the drawing according to the thickness. The design of thick and thin tubes is different.

Tolerances and Quality Standards:

Roundness: +/-0.05mm; Flatness:+/-0.04mm

Types of Roll Profiles:

Roll profiles in steel tube mills can be categorized based on their specific functions and stages in the tube-forming process:

Forming Rolls:

These are the initial rolls that begin forming the flat strip into a round shape. Breakdown rolls are crucial in setting the foundation for the subsequent forming stages.

Welding Rolls:

Positioned at the welding stage, these rolls apply pressure to ensure a solid and uniform weld seam. Proper design of welding rolls is vital for weld quality.

Sizing Rolls:

After welding, sizing rolls are used to achieve the final tube dimensions and to correct any distortions. They ensure that the tube meets the required specifications for diameter and roundness.

Reshaping Rolls:

For tubes requiring specific shapes (e.g., square or rectangular), reshaping rolls adjust the tube's form to the desired profile. These rolls are essential for producing non-cylindrical tubes.Functions of Roll Profiles

Conclusion

The tube mill roll profile is directly influencing the tube quality, dimensions, and overall success of the tube-forming process.
