Reduction Rolling Mills

High-efficiency Reduction Rolling Mills | Professional manufacturers provide high-quality reducing equipment

RM-J type Reduction Rolling Mills are specially designed for precision diameter reduction of metal pipes and bars. It is suitable for carbon steel, stainless steel, alloy steel and other materials. It is designed to achieve the purpose of reducing the diameter of materials through processing processes such as wire laying, heating, rolling forming, and coiling. During the processing, the rolling speed and roll gap can be adjusted independently according to the process requirements to meet the production requirements of different materials.

The equipment adopts advanced technology to ensure a high-precision, high-speed and high-reliability production process, solving the pain points of large dimensional fluctuations (±0.2mm), low efficiency and rough surface in traditional processing, and achieving an outer diameter accuracy of ±0.01mm.

Application areas:

Oil pipeline: API 5L pipeline steel reduced from Φ219mm to Φ168mm, ovality ≤0.5%

Auto parts: Drive shaft bar Φ50mm→Φ35mm (surface roughness Ra1.6μm)

Machinery manufacturing: Precision diameter reduction of hydraulic cylinder tube (straightness ≤0.1mm/m)

Construction materials: Batch processing of scaffolding tubes (daily production capacity ≥50 tons)

Core advantages:

1. Multi-pass continuous rolling

Flexible configuration of 1-14 passes, maximum outer diameter reduction rate of single processing 30%

Support online dimension detection closed-loop control (laser side diameter gauge ±0.01mm)

2. Intelligent temperature control system

Internal water cooling + external spray cooling of the roller, temperature fluctuation ≤±3℃

Avoid lattice distortion caused by overheating of the material

3. Modular quick-change design:

The roller module can be replaced within 30 minutes (traditional equipment requires 2 hours)

4. Energy-saving and efficient drive: permanent magnet synchronous motor + servo feedback system + current closed loop

5. Industrial 4.0 Internet of Things

Supports remote monitoring on mobile phone APP/PC, data docking MES/EPR

Fault self-diagnosis rate ≥95%

6. Super wear-resistant and corrosion-resistant structure

42CrMo alloy steel roller body to ensure the durability and processing accuracy of the roller

7. Precision guide device: suitable for round/elliptical or square/round diameter reduction
