【摘要】 .板带钢作为钢铁制造业的主要产品之一,在汽车工业、船舶、航空、机械制造和建筑工业等方面获得了普遍的应用。板带钢的外形及表面质量是冷、热轧板材的一项重要质量指标,随着金属加工业生产的发展,对薄板带钢的板形质量要求越来越高。本文在深入研究现有板形检测方法的基础上,结合应用激光板形及表面缺陷检测的技术,研究和开发出适用于板材集多种板形检测方法和表面缺陷检测于一体的实验检测装置,并详细介绍了该检测装置的设计原理和特点,并在该装置上进行板形和表面缺陷检测的模拟实验研究,其结果表明：该板形检测装置采用机、电、液一体化控制具有一定的智能化,可完全满足于接触式或非接触式测量的位置,而且空间尺寸可进行调整。本检测装置调试和维修比较方便,可采用手动和自动两种操作方式进行操作,使用方便。本板形检测装置采用590调速系统可实现无级调速,满足调速范围为1-20m/s,而且依据断面尺寸与材料的屈服强度还能实现张力范围的调整。采用本检测装置运用激光方法检测板形,实际检测结果与剖条实验结果对比,可以完全满足于板材板形在线实时检测的精度要求,并且可以作为在线进行实测结果的反馈信息。该板材板形检测装置易于移植到实际生产现场进行在线板形和表面缺陷检测。更多还原

【Abstract】 As one of the major products of iron and steel manufacture, sheet plate is widely used in the automobile industry, shipbuilding, aviation, construction industry and so on. For the cold or hot rolled sheet plates, the shape and surface quality is an important quality index (QI), and the QI has increasingly raised due to the development of the metal-processing industry. In this paper, a new detecting device of multi-shape and surface defect was invented and developed, based on the principle of the current shape detecting method and the application of laser and surface defect detecting techniques. The design principle and features of the detecting device were described in detail. Employing this device, a simulation research of the shape and surface defect detection of sheet plates was made. The experimental results showed that:This plate shape detecting device integrating mechanical, electrical and hydraulic monitoring was an artificial intelligence instrument which can fully satisfied with the requirement of the contact or non-contact measuring location and the adjustment of the measuring space size. The debugging and maintenance of the detecting device is convenient, and the operation of the device is viable both by manual and automatic style. This plate shape detecting device can perform grade-free speed control by using the 590 speed controlling system on the speed range of 1-20m/s. Adjustment of tension ranges can be achieved according to the cross-section dimensions and yield strength of the detected materials. Compared with the traditional cutting test results, the detecting results using this detecting device by laser method can satisfied with the accuracy requirement of the shape detecting online and feed back the information online. This plate shape detecting device can be easily transplanted to the actual production field to detect the plate shape and surface defect online.更多还原
