钢坯的质量对由钢坯轧出的轧制成品的表面状况有较大影响。但是,在很多情况下,这种检查仍然是靠人们的视觉。所以它的自动化程度是不够的。我们把“工业电视系统”应用到这种检查作业线上,以便用莹光磁粉检查的方法来识别缺陷图象。四个具有高灵敏度的电视机摄象管和一些电路能摄下钢坯四个面的莹光缺陷图象,判断他们有害或无害并驱动打印机系统。这些检查数据通过微型计算机进行处理,而检查过的钢坯按照检查的结果进行自动分数。用工业电视系统检查缺陷的效果比用一般的目测检查大约高14％。
The quality of the billet has a significant influence on the surface condition of the rolled product rolled out of the billet. However, in many cases, this inspection is still based on people’s vision. So its degree of automation is not enough. We applied “industrial television systems” to such inspection operations to identify defective images with fluorescent magnetic particle inspection. Four high-sensitivity television picture tubes and some circuits capture images of fluorescent defects on the four sides of the billet to determine whether they are harmful or harmless and drive the printer system. These inspection data are processed by a microcomputer, and the checked billet is automatically fractionated according to the inspection result. The effect of inspecting defects with an industrial television system is about 14% higher than with normal visual inspection.
