Power Supply System
Steel Pipe Online Temperature Compensation Equipment adopts dual rectifier 12-pulse or 24-pulse power supply. The power range is 500KW-10000KW, and the operating frequency is 1000-2500HZ. A single power supply can operate independently, and multiple power supplies can work in parallel synchronously.
Feeding System
1.Each conveying shaft is driven by an independent motor and reducer.
2.Each shaft is equipped with an independent frequency converter for separate speed regulation.
3.Differential speed output can be set flexibly, and the operating speed can be controlled in sections.
Guiding System
1.Guide wheels are made of 304 non-magnetic stainless steel.
2.High-precision digital encoders are installed on the system.
3.Encoders automatically identify and locate the height of workpieces with different specifications.
Automatic Temperature Control System
1.It adopts Yuantuo's exclusive feedforward plus feedback combined control mode.
2.Feedforward control: The system collects inlet temperature and position data of workpieces, and automatically matches the corresponding power output.
3.Feedback control: The system collects outlet temperature data and makes secondary calibration for power values.
4.Performance index: When the inlet temperature difference of workpieces reaches 300℃, the outlet temperature difference can be controlled within ±10℃.
Formula Management Function
1.The device is equipped with a complete standardized formula management program.
2.Operators input production parameters including steel grade, outer diameter and wall thickness.
3.The system automatically calls the full set of operating parameters for the specified workpiece.
4.Manual repeated recording, searching and parameter input for different workpieces are no longer required.
Product Advantages
Strong adaptability to power loads
Steel Pipe Online Temperature Compensation Equipment features dual rectifier 12-pulse / 24-pulse power supply. With 500KW-10000KW power and 1000-2500HZ frequency, it supports standalone and parallel operation, matching heat treatment production lines of different capacities.
Stable feeding accuracy
Each feeding shaft has independent motor reducer and frequency converter. Adjustable differential speed and sectional speed control ensure smooth conveyance without collision or displacement of steel pipes.
High guiding and positioning precision
304 non-magnetic stainless steel guide wheels and high-precision digital encoders realize automatic height positioning for steel pipes of various sizes, supporting flexible production switching.
Leading temperature control precision
The feedforward-feedback combined control ensures even heating of steel pipes and consistent heat treatment quality, with outlet temperature fluctuation limited to ±10℃ even under 300℃ inlet temperature difference.
High intelligent operation level
The built-in formula system loads full operating parameters after entering three basic indexes, eliminating manual repeated parameter entry and reducing human errors.
Good expandability and compatibility
Production capacity can be upgraded by adding extra units. Modular subsystems allow separate inspection and maintenance without halting the whole production line, cutting downtime loss.
Factory scene
Application Matching
Extra units can be deployed to expand overall output, suitable for continuous line processes such as quenching and tempering, tempering, secondary heating of continuous casting billets and thick-wall pipe heating. Modular separated control of all subsystems enables individual troubleshooting and maintenance to reduce line downtime. Full automatic regulation minimizes parameter deviation caused by manual operation and stabilizes heat treatment uniformity of finished steel pipes. High-power parallel power supply structure supports mass continuous production of large-diameter and thick-wall steel pipes with high throughput.
