薄板超声波检测方法及工艺试验研究

摘要

板材在坯料和轧制过程中容易产生裂纹、夹杂物、气孔等危害性缺陷,该板材因厚度薄,一般在4 mm以下,需通过对超声波检测方法、设备和器材、检测标准的研究提出超声波检测方案,达到对高温合金薄板品质进行有效控制.%Cracking,slag,gas holes on the plate are easily caused during blanket rolling. Because the plate's thickness is under 4 micrometers, it is necessary to research on method of ultrasonic testing, equipment, material and testing standards to assure effective control of the thin plate.
