The entire feeding process of using a complete set of double groove molds for punching C-shaped steel manufacturers greatly improves the tapping effect, and the work efficiency of CNC cutting machine is also greatly improved. After cutting the punched C-shaped steel, the crack extends along the cutting edge of the steel towards the base, and the width of the crack is from the front end to the base. Gradually reduce to form thick, low plastic areas at the edges. The arrangement structure of cutting edges is similar to the structural changes in the affected zone of the heating zone, and punching C-shaped steel has varying degrees of compressive stress, which is the primary reason for delayed cracking.

在沖孔C型鋼生產過程中，很難避免冷卻過程構成的板材剩余應力。因而，鋼板切開變形嚴重影響客戶運用。因而，控制冷卻技能的優化和剩余應力場的猜測已成為煉鋼職業的熱點。

It is difficult to avoid the residual stress caused by the cooling process in the production of punched C-shaped steel. Therefore, the cutting deformation of the steel plate seriously affects the customer's use. Therefore, the optimization of control cooling skills and the speculation of residual stress fields have become hot topics in the steelmaking profession.

在現有工程項目的基礎上，一起對大型沖孔C型鋼切開過程中的軌道盯梢和軌道信息獲取進行了研討。首要討論了硬件挑選的類型和已完結的雙目視覺盯梢體系的結構，以及首要硬件挑選的細節，并解說了每個設備在體系中的作用，以完結規劃。可視化監控體系，為下一步的研討和試驗基地的引入供給合適的渠道。

On the basis of existing engineering projects, a discussion was conducted on the track tracking and track information acquisition during the cutting process of large punched C-shaped steel. The types of hardware selection and the structure of the completed binocular visual tracking system were primarily discussed, as well as the details of the primary hardware selection. The role of each device in the system was explained to complete the planning. The visual monitoring system provides suitable channels for the next step of research and the introduction of experimental bases.

在這項工作中，對不同軌道的軌道進行了提取和測試，并對軌道提取算法進行了驗證。在沖孔C型鋼的切鋼過程中，沿直線斜切，查看線和鋼筋。進行三維重建后，供給重建圖畫和軌道參數的作用，并在某些情況下，匯總軌道誤差，供給盯梢調整誤差算法，并經過串行通訊在下位機進行誤差調整。

In this work, different trajectories were extracted and tested, and the trajectory extraction algorithm was validated. During the steel cutting process of punching C-shaped steel, oblique cutting is carried out along a straight line to check the line and reinforcement. After Iterative reconstruction, provide the function of reconstruction picture and track parameters, and in some cases, summarize the track error, provide the tracking adjustment error algorithm, and adjust the error on the lower computer through serial communication.
