I. Project Background: The "Efficiency Revolution" in High-Speed Bar Technology
Since the emergence of high-speed steel entry system technology in 1971, high-speed bar production lines have become a benchmark for efficient production in the steel industry, thanks to their core advantages of "high precision, high output, and high yield." Among these, the double high-speed bar process, exemplified by Danieli's "High-Speed Twin Channel (HTC) Conveyor System" (which integrates "splitting technology with high-speed production"), has elevated the efficiency and flexibility of bar production to new heights.
In the double high-speed bar production line, the twin-channel four-turret entry equipment serves as a critical hub: it is responsible for temporarily storing the rolled product during the braking process and accurately transferring it to the cooling bed after the product comes to a stop. Given that the speed of the rolled product in high-speed bar mills far exceeds that of conventional lines, the "turret drive" of the entry equipment imposes nearly stringent demands on the synchronization and control precision of the power system.
II. Customer Needs: Power Transmission Challenges Under "High Speed + Precision"
In a specific Danieli double high-speed bar production line project, the turret drive of the entry equipment faced three core challenges:
Synchronization Requirement: Each turret requires coordinated drive by "head and tail dual servo motors." These two motors must achieve millisecond-level synchronous response to ensure smooth turret operation and prevent conveying deviation or jamming of the rolled product.
Control Precision Requirement: The "precise stopping" of the high-speed rolled product relies on the motor's high-precision control of speed and position. The error must be kept within an extremely small range to match the receiving rhythm of the cooling bed.
Balancing Economy and Reliability: It is essential to meet the performance requirements of the high-end process while also considering long-term operational costs and stability, ensuring efficient production throughout the entire lifecycle of the production line.
III. Solution: The "Precision Breakthrough" of Oemer QL100P Servo Motors
As the authorized domestic agent for Italian Oemer servo motors, Beijing Handelsen Mechanical Technology Co., Ltd. provided the Oemer QL100P series servo motors for the project, offering a "customized power solution" to address the technical challenges of high-speed entry.
(A) Core Product Advantages:
Extreme Synchronization Performance: The QL100P series incorporates advanced magnetic circuit design and vector control technology. When dual motors operate cooperatively, the synchronization error can be controlled within a smaller response range, perfectly meeting the stringent demands of the turret's "head-tail synchronous drive."
High-Precision Control Capability: The motor features a built-in high-precision encoder, enabling precise control of speed and position. This ensures the rolled product is accurately conveyed to the designated position on the cooling bed after high-speed braking.
High Reliability and Economy: The motors are manufactured using industrial-grade materials resistant to wear and impact, allowing them to adapt to harsh environments such as "high temperature and dust" in steel production lines. Simultaneously, the balanced design of "high performance + low cost" significantly reduces equipment procurement and operation/maintenance costs.
IV. Application Results: From "Technical Challenge" to "Efficient Production"
The application of Oemer QL100P servo motors in the Danieli double high-speed bar entry equipment achieved multiple breakthroughs:
Production Efficiency Improvement: The synchronization and precision of the turret drive enabled perfect matching between the conveying rhythm of the rolled product and the receiving efficiency of the cooling bed, increasing the overall production line efficiency compared to traditional solutions.
Yield Optimization: Issues such as "deviation and collision" during the conveying of the rolled product were reduced.
Reduced Operation and Maintenance Costs: The high reliability of the motors lowered the equipment failure rate, decreasing downtime for maintenance and spare part replacement costs.
V. Case Summary: High-End Motors Empower Intelligent Manufacturing
The successful application of the Italian Oemer QL100P series servo motors in the Danieli double high-speed bar production line not only verifies their reliable performance under "high-speed, precise, and harsh environmental" conditions but also demonstrates Beijing Handelsen's capability in "resource integration + technical service" within the field of industrial high-end motors.
In the future, as the steel industry's demand for "efficient and intelligent production" continues to grow, this type of "precision power" servo motor will play a key role in more high-end production lines, injecting stronger momentum into intelligent manufacturing.
