Operational Considerations for the Furiwo 76 Used High-Frequency Welding Pipe Mill in Production

Operating a used pipe mill effectively and safely requires strict adherence to specific protocols, especially given its prior service history and the high-power, mechanical nature of its processes. The following key considerations are essential for the Furiwo 76 model to ensure product quality, operational efficiency, and personnel safety.

1. Pre-Operational Inspection and Setup:
Before initiating any production run, a comprehensive inspection of this used pipe mill is mandatory. Verify that all maintenance and renovation records are reviewed. Check the integrity of critical components: ensure the manual double cone uncoiler brakes and cones function smoothly, confirm the horizontal loop carriage moves without obstruction, and inspect all forming and sizing rolls (Φ60) for significant wear, cracks, or surface damage that could affect pipe profile. Crucially, test all electrical systems, including the 200kW main drive motor, the 300kW high-frequency welder, and the 22kW/30kW cutting saw servo system, during a no-load startup sequence to ensure stability. Properly install and align the tooling sets specific to the target pipe size (e.g., round Φ20-76mm, square up to 60x60mm).

2. Operational Monitoring and Adjustment:
During production, continuous monitoring is vital. First, ensure the strip steel feeds from the right-hand side smoothly without snagging at the uncoiler or entry guides. Monitor the horizontal loop level to maintain consistent feed pressure and prevent strip breakage or buckling. Second, closely observe the forming process. The sequence of 7 horizontal and 8 vertical stands must progressively shape the strip correctly; any misalignment can lead to poor seam preparation. Third, the high-frequency welding process is critical. Monitor the welder's parameters (power, frequency, V-angle) constantly. A stable, consistent weld spark is indicative of proper operation. Irregularities can cause weak welds or pinholes. Finally, the sizing section (5 horizontal and 5 vertical stands) determines final dimensional accuracy. Regularly sample cut pipes to verify outside diameter, wall thickness (for ranges of 0.8-4.0mm), and squareness/rectangularity against specifications.

3. Safety and Maintenance Protocols:
Safety is paramount when operating heavy machinery like a used pipe mill. All operators must wear appropriate Personal Protective Equipment (PPE): safety glasses, hearing protection, heat-resistant gloves, and protective footwear. Ensure all safety guards, especially around the high-frequency welder, rotating shafts, and the cutting saw, are securely in place. The emergency stop system must be tested and functional. Lockout-Tagout (LOTO) procedures must be strictly followed during any mold changes, clearing of jams, or maintenance. Given that this is a used pipe mill, particular attention should be paid to the condition of hydraulic lines, gearboxes, and bearing housings for signs of leaks or unusual noise, which might indicate wear from prior use.

4. Post-Operation and Preventative Maintenance:
After completing a production run, conduct a thorough shutdown procedure. Power down systems in sequence, clear any scrap material from the line, and clean critical components like the rolls to prevent rust or material buildup. Establish a rigorous preventative maintenance schedule tailored for a refurbished used pipe mill. This includes regularly lubricating all bearings and gearboxes, checking and tightening bolts on roll stands, calibrating the servo cutting system for length accuracy, and periodically inspecting and cleaning the high-frequency welder's contacts, oscillator, and cooling system. Keeping detailed logs of operational hours, maintenance activities, and any recurring issues is crucial for managing the long-term reliability of the equipment.

In summary, successful operation of the Furiwo 76 used pipe mill hinges on diligent pre-checks, real-time process monitoring, unwavering commitment to safety standards, and a robust, proactive maintenance regimen. These practices maximize the productivity and lifespan of the equipment while ensuring a safe working environment and consistent output quality.
