Abstract:Copper and copper alloys horizontal continuous casting billets usually have defects such as pores, porosity, and cracks, which seriously affect the product quality and pass rate. Various defects of the casting billets were detected and displayed accurately by using the C-scan imaging technology and multi-channel scanning technology based on the principle of ultrasonic detection, and also, the testing equipment was designed and developed to perform online reciprocating detection, the online detecting results of the horizontal continuous casting copper billets were verified, and metallographic tests were conducted to detected abnormalities. In this way, we can confirm whether the abnormal part is a defect and verify the accuracy of the detection result of the equipment. Collect the yield data of subsequent copper strips, compare and analyze the two sets of test data, and give the relationship between the two. This device has the advantages of real-time feedback of detection data and high-precision detection, and also provide reference for actual production of enterprises.
