The ultrasonic flaw detection method is online by the linear sensor array consisting of wireless transmission probe and receiving probe (frequency 25MHz) component. Send a probe to send to the plate by the ultrasonic radiation, receiving the probe to collect trees from the pot surface and internal defects of inclusions shows the reflected wave: At this point the width of receiving a certain range of the probe to show the defect. So that by the time to send and receive ultrasonic flaw detection method for continuous testing can strip line. Online ultrasonic testing of newly developed method to evaluate the effects. Be checked by the line 20-26ram pickling steel. Then off-line testing method testing. The results confirm that the new online testing method developed by more than 10dB S / N can check out the 60x3Oum (length × width) size of the defects of inclusion, that you can check out the 5 × 10m the following deficiencies are the new online testing method has been iron by the company Chiba pickling production line of steel in the pickling tank to set population side, using six rolls transferred to the sink in the strip - unadorned stains. Detection devices to send and receive probes corresponding to the probe was staggered configuration, continuous testing of the strip, the actual good effect, not the phenomenon of false detection of defects very good reproducibility, Kuang online check out the 5x1 m (diameter of about 5o, um ) inclusion defects,[link widoczny dla zalogowanych], can guarantee the internal steel quality. Zhang Zhaosheng Quoted \growing, with China's national economy, a 7% annual increase rate of l0%, China and the WTO plus all the 2008 Olympic Games will bring China's steel industry development opportunities. To strengthen the information industry, and advocacy through Amoy, recommended the advanced enterprise technology and products,[link widoczny dla zalogowanych], the Chinese Association of Mountain l Torr pan structure to be published \This book is the first steel structure in the field of enterprises directory, it will be the technical work in the steel enterprises large platform for the exchange of information,[link widoczny dla zalogowanych], all enterprises and institutions to the market structure of the bridge Liang Zhongguo Association will fully actinides to go to to promote the development of China's steel industry to play its due role. \Branch and invited the relevant enterprises and institutions to support it.
