为提高冷轧带钢板形检测精度,研制出一种新型的冷轧带钢板形仪———整辊镶块智能型板形仪。该板形仪提出与国际上流行的分段式检测辊不同的结构形式,研制了整辊镶块式检测辊,以避免传统检测辊辊片之间由于热膨胀不同对带钢表面造成的划伤;提出与国际上流行的干式集流环不同的信号集流传输方式,研制了喷淋湿式集流环,以提高检测精度和使用寿命;提出与国际上流行的采集卡形式不同的信号处理方式,研制了嵌入式DSP板形信号处理硬件系统,以提高检测精度和抗干扰能力;研发了具有误差补偿、模式识别、目标板形制定和闭环控制计算功能的板形信号处理软件系统,以实现板形仪的智能化。该板形仪经在鞍钢1 250mm冷轧机上实际工业考验证明,测量信号稳定可靠,而且实现了板形闭环控制。
In order to improve the detection accuracy of cold-rolled strip shape, a new type of cold-rolled strip shape meter is developed, which is an intelligent strip shape meter with full roll inlay. The shape meter proposed with the internationally popular segmented detection roller different structural forms, developed a roll-in-block inspection roller, in order to avoid the traditional detection of roller due to thermal expansion of the strip on the surface of the scratch ; Put forward with the international prevalence of the dry flow collection ring different signal flow transmission methods developed spray wet slip ring to improve the detection accuracy and service life; proposed with the internationally popular capture card in the form of different signal processing The hardware system of embedded DSP plate signal processing was developed in order to improve the detection accuracy and anti-jamming capability. The plate signal processing software system with error compensation, pattern recognition, target shape and closed loop control was developed Realize the intelligent shape sensor. The plate-shaped instrument by Anshan Iron and Steel 250mm cold rolling mill in the actual industrial test proved that the measurement signal is stable and reliable, and the realization of the plate-shaped closed-loop control.
