Uzbekistan Steel Manufacturer Purchases 2 Sets of JIAKE High-Speed Cold Rolled 3-Ribbed Steel Bar Production Lines
Client Background & Steel Processing Capacity Expansion in Uzbekistan
The booming construction sector in Uzbekistan and Central Asia has driven an unprecedented demand for high-strength reinforced steel bars (rebar). Cold rolled ribbed steel bars, especially 3-ribbed deformed steel bars, are widely utilized in concrete mesh reinforcement, precast concrete structures, and residential building foundations due to their superior bonding strength with concrete and elevated yield strength.
A leading local steel manufacturer in Uzbekistan sought to significantly expand their daily yield of 5mm ribbed rebar. Their standard raw material consisted of 6.5mm low-carbon steel wire rods in coils. To achieve maximum production efficiency, the client required a continuous processing solution that could reduce wire diameter from 6.5mm to 5mm, cold-roll precise 3-ribbed profiles, straighten the bar without surface damage, and cut it into exact 2-meter fixed lengths at high speeds.
Recognizing the need for high output and minimal downtime, the client decided to invest in 2 complete production lines simultaneously. They turned to JIAKE Machinery for a fully integrated, automated engineering solution.
Technical Solution: JIAKE Integrated 3-Ribbed Steel Bar Processing Line
To fulfill the client’s strict requirements for dimensional accuracy, rib profile consistency, and cutting speed, JIAKE senior engineers designed a complete end-to-end Cold Rolled 3-Ribbed Rebar machine. Built with a modular structure, each line seamlessly integrates mechanical descaling, cold reduction, profile rolling, servo flying shearing, and automatic stacking.
| Production Unit | Uzbek Client Specification | JIAKE Custom Engineering Solution |
|---|---|---|
| Raw Material & Pay-off | 6.5mm Low Carbon Steel Wire Rod Coils | Heavy-duty passive pay-off stand ensuring continuous wire uncoiling without snagging. |
| Surface Pretreating | Mechanical Descaling & Lubrication | Multi-wheel mechanical descaler with dry powder lubrication box for smooth drawing. |
| Diameter Reduction Unit | 6.5mm down to 5.0mm smooth round wire | High-rigidity cold reduction cassette equipped with alloy tungsten carbide dies. |
| Rib Rolling Unit | Cold-rolled 3-ribbed (crescent/indented) profile | Precision 3-roll cold ribbing machine for uniform rib height and pitch distribution. |
| Straightening & Shearing | High-speed straightening to 2.0m fixed length | Multi-roller straightening unit paired with a high-precision servo flying shear system. |
| Control & Electricals | High precision, minimal length error (≤±1mm) | Siemens PLC, Schneider air switches/contactors, and Taiwan Delta speed reducers. |
Key Engineering Highlights of JIAKE 3-Ribbed Rebar Machine
1. Precision 3-Rib Rolling Technology
The cold ribbing unit utilizes three synchronized carbide rolling rollers positioned at 120-degree intervals. As the reduced 5mm steel wire passes through, the rollers form sharp, uniform 3-ribbed indented surface patterns. This cold deformation process increases the tensile and yield strength of the raw wire rod by over 20%, satisfying international structural steel standards.
2. High-Speed Servo Flying Shear & Zero-Stop Cutting
To cut the 5mm 3-ribbed rebar into exact 2-meter lengths without stopping the continuous rolling process, JIAKE integrated an advanced servo motor-driven flying shear system. Synchronized dynamically with the line speed via an encoder, the flying shear achieves rapid, burr-free cutting with a length tolerance within ±1mm, drastically boosting total line output.
3. World-Class Electrical Components & Smart Control
Reliability in continuous industrial operation depends on premium electrical architecture. JIAKE built the control system using top-tier international components:
- Siemens PLC & Touchscreen: Centralized control interface for real-time speed monitoring, length configuration, and diagnostic alarms.
- Schneider Electric Switches & Contactors: Superior circuit protection and electrical stability under heavy continuous loads.
- Taiwan Delta Reducers & Drives: High-torque transmission with high energy efficiency and low noise operation.
Factory Testing, Purchase Order & On-Site Delivery
During factory commissioning at JIAKE’s manufacturing facility, both production lines underwent rigorous 24-hour test runs. The 6.8mm/6.5mm raw wire rod was reduced to 5mm, cold-rolled into clean 3-ribbed profiles, and sheared precisely into 2-meter lengths at high line speeds.
Impressed by the line stability, precision cutting, robust mechanical assembly, and intuitive Siemens touch control, the delegation from Uzbekistan signed the final procurement agreement for 2 complete cold rolling ribbed bar production lines on the spot.
