日本日新钢铁公司自1984年开始,在周南厂开发研制了连续退火和酸洗线用的表面检测装置。1986年1月,该公司将已日趋完善的这套装置投入了使用,以确保进一步提高不锈钢产品质量。该检测装置使用三种传感器,以便检测出产品正、反两表面的孔洞和缺陷。来自传感器 Japan’s Nippon Steel and Steel Company since 1984, Zhou Nan plant developed a continuous annealing and pickling line with the surface inspection device. In January 1986, the company put the increasingly sophisticated unit in place to ensure further improvement of the stainless steel product quality. The test device uses three sensors in order to detect the positive and negative surfaces of the product holes and defects. From the sensor
