What is the purpose of Single Stand Multi-Groove Reducing Rolling Mill

1、 Basic definition of equipment

Single Stand Multi-Groove Reducing Rolling Mill: With only one main stand, multiple holes and slots with different diameters are made on the rolling mill rolls. One device can switch and roll various outer diameter specifications of bars and pipes. Different from multi stand series tension reducing mills, it has low investment, small footprint, and fast specification change, mainly for cold rolling/warm rolling small profiles.

2、 Bar round steel/steel bar processing (maximum application scenario)

Screw thread steel to smooth circle

Large specification threaded steel (Φ 25, Φ 28, Φ 32) is rolled and reduced into high-precision round solid bars, used for building embedded parts, mechanical pin shafts, foundation bolt blanks, and steel structure connectors; Prepare 2-5 finished product sizes in multiple slots at once, without the need for frequent roll changes.

Alloy steel, mold steel, high-speed steel bar material finishing

The size deviation of hot-rolled blanks is large, and the single stand multi groove gradually reduces the diameter, corrects roundness and outer diameter tolerances, and improves surface smoothness; Mass production of raw materials for shafts, gears, and fasteners.

Nonferrous metal round rod

Reducing and shaping copper rods, aluminum rods, brass rods, and copper conductive rods, suitable for busbars, metal stamping, and plumbing pipe fittings blanks; Soft metal rolling is not easy to crack, and the specifications can be flexibly switched between multiple slots.

3、 Seamless/welded pipe precision reduction and sizing

Small caliber fluid steel pipe, conduit, plumbing steel pipe

When the outer diameter of the waste pipe is too large, the single rack with multiple slots and small deformation can fine tune the outer diameter, uniformly round the pipe wall, and improve dimensional accuracy; Suitable for small-scale production of thin-walled decorative pipes, building wiring pipes, and guardrail pipes.

Pre formed heat dissipation tubes and heat exchange base tubes

The compressed air cooler tubes and radiator aluminum/steel tubes are roughly rolled and shaped, with multiple slots matching different heat exchange tube diameters. After rolling, they are precision machined and brazed for assembly.

Cable protection steel pipe

Reducing the diameter of insulated sheathed steel pipes, some models can simultaneously roll outer wall reinforcement bars to improve the compressive and torsional performance of steel pipes, used for pre embedded laying of engineering cables.

4、 Special purpose in the construction industry

Prefabrication of steel structure fittings blanks

The precision machining of reducing diameter for curtain wall bolts, bracket round steel, guardrail column round pipes, and steel structure braces can accommodate multiple accessory specifications in one device, and small processing plants do not require multiple rolling mills.

Processing of raw materials for prestressed components

Small prestressed round steel and tensioning anchor rod size correction to ensure consistency in tensile dimensions.

Scaffolding, pipe fittings

Reduce the diameter of the end of the scaffold circular tube, roll the connecting sleeve blank, and unify the assembly and fit clearance.

5、 Rolling of raw materials for hardware and mechanical components

Standard parts: bolts, nuts, rivets, pin bars, precision rolled and reduced diameter;

Construction machinery small shaft, liner, and small piston rod blank shaping;

Ironwork, railings, and decorative metal profiles with round rods for diameter adjustment.

6、 Core equipment advantages (multi slot design value)

One machine with multiple specifications: A single roller is equipped with 3-5 sets of holes and grooves, and changing the size only requires fine-tuning the front and rear guides and speed regulation, without the need to disassemble and replace the roller, greatly reducing the production time;

Low investment cost: Compared with multi stand continuous rolling mills, it occupies a small area and has fewer motor reducers, making it suitable for small and medium-sized processing plants and multi specification small batch orders;

Easy to operate and maintain: The single rack structure has strong rigidity and requires less lubrication, maintenance, and roller replacement work;

Micro deformation finishing is the main focus: the single pass diameter reduction is moderate, suitable for high-precision and low cracking requirements of non-ferrous metals and thin-walled pipes; The demand for large diameter reduction can be repeatedly rolled back and forth.
