In the competitive world of steel, having a reliable, high-performance production line isn’t just an asset—it’s a necessity.
I’m excited to showcase our flagship 1250 Hot Rolling Strip Mill Line, a comprehensive solution built to meet the exacting standards of the global market. From precision descaling to final product finishing, every component is optimized for maximum performance and minimal downtime. Here’s why this line is the preferred choice for steel mills worldwide.
🛠️ Core Equipment & Technical Excellence
Every component of our 1250 line is engineered to maximize performance and minimize operational costs:
1. Roughing & Finishing Descalers
- Purpose: Eliminate primary/secondary scale from slab surfaces, ensuring a clean, oxide-free finish critical for downstream processing (pickling, cold rolling, coating).
- Key Specs: 18 MPa high-pressure water jets, adjustable nozzle angles (13.2–15°), and precision spray width control (1100 mm) to remove scale without damaging the base material. The roller table uses solid forged steel rolls driven by individual AC variable-frequency motors, ensuring stable slab transport at 0–1.2 m/s (roughing) and 2.1 m/s (finishing).
- Business Impact: Reduces surface defects by 30%+ and cuts rework costs, directly improving your product yield and customer satisfaction. The modular design also allows for quick maintenance, minimizing downtime during descaling box overhauls.
2. R1 Two-High Reversing Mill
- Purpose: Transform reheated slabs into 30–45 mm intermediate slabs via 5–7 precision passes, laying the foundation for final product quality.
- Key Specs: 20,000 kN rolling force, hydraulic screw-down control (HGC), and 2.25x overload capacity to handle tough materials (carbon steel, low alloy steel). The closed-end frame structure ensures rigidity under heavy loads, while Babbitt alloy bearings with oil circulation lubrication extend service life.
- Business Impact: Delivers tight thickness tolerance (<±0.1 mm) and uniform mechanical properties, ensuring your intermediate slabs are ready for high-precision finishing. The manual return mechanism for the backward pull system adds operational flexibility, reducing downtime during pass adjustments.
3. Crop Shear
Purpose: Precisely trim the head/tail of intermediate slabs at 900°C+, eliminating defects and optimizing material utilization.
- Key Specs: 600 kN shearing force, pendulum design, and manual online gap adjustment to match mill entry speed (0.5–2 m/s). The blades are made of high-strength wear-resistant material and water-cooled to maintain cutting performance at high temperatures.
- Business Impact: Reduces material waste by up to 5% and ensures smooth entry into the finishing mill, avoiding production disruptions. The safety valve system (21 MPa) protects against overloads, enhancing operational safety for your team.
4. F1–F6 Finishing Mill Stands
- Purpose: Continuously reduce intermediate slabs to final strip thickness (down to 2.0 mm) while maintaining precise shape and flatness.
- Key Specs: Four-high configuration, hydraulic AGC (Automatic Gauge Control), work roll bending/shifting, and 50 m/s maximum rolling speed. Each stand is equipped with a thickness gauge and shape meter for real-time quality monitoring, ensuring consistent product performance across the entire coil length.
- Business Impact: Achieves industry-leading thickness tolerance (<±0.05 mm) and flatness control, making your final strips ideal for automotive, construction, and appliance manufacturing. The variable-speed drive system also optimizes energy consumption, cutting operational costs per ton of steel.
