CONSTITUTION:A transmitting end 1 and a receiving end 2 are incorporated into a unitary body, and water is supplied into a junction between said body and a steel plate 3 as an acoustic medium from a water nozzle 4. By using such a transmitter T and a receiver R, the pulse shaped elastic wave is transmitted in the direction of the thickness of the steel plate 3 from the transmitting end 1. The back echo from the bottom surface is received by the receiving end 2. The transmission speed and the elastic constant in the steel plate are measured from the transmission time. From these data, the average aggregation organization and the material characteristics based on said aggregation organization in the direction of the plate thickness is measured. Then the energy of the received elastic wave is measured. From the ratio between said value and the energy of the transmitted elastic wave, the average crystal grain size in the direction of the plate thickness of the object to be measured is obtained.

摘要： PURPOSE:To elevate the dimensional accuracy of a product and pipe making efficiency by making the number of rolling reduction times for diameter shrinkage within the specified range in the rolling stage equipping a thickness deviation correcting function as well to a piercing and extension function. CONSTITUTION:The number of rolling reduction times for diameter shrinkage is set within the range of 1-15 times in case of rolling a seamless pipe with placing a diameter shrinkage rolling reduction by the rear half part of a roll 11 on the stock 13 to be rolled by plural inclined rolls 11 and a plug 12. Since it is the case of the number of the diameter shrinkage rolling reduction times N being >=1 that the thickness deviation correcting effect is realized on the practical level by the diameter shrinkage rolling reduction work, the low limit value of the number of times N is taken as one. On the other hand the more the number of times N is increased the more the thickness deviation improvement rate is increased and for instance it is necessary to elongate the body length of the roll part III of the roll II so as to make the number of times N in twenty or more in order to secure the thickness deviation improvement rate of >=90%. Also since there is a fear of the reduction in the roll strength against the rolling load it is practical to set an upper limit value on the number of times N and the upper limit value is taken as fifteen based on the fact that the product of high accuracy of never been before can be offered.
摘要翻译：目的：通过将轧制阶段的直径收缩率在规定范围内的轧制次数与厚度偏差校正功能以及穿孔和延伸功能相结合，提高产品的尺寸精度和管道制作效率。构成：轧制无缝管的情况下，直径收缩的轧制次数设定在1-15倍的范围内，将辊11的后半部分的直径收缩轧制压下量放置在坯料13上为由多个倾斜辊11和塞子12卷绕而成。由于直径收缩轧制压下次数N大于等于1的情况，所以通过直径收缩压下轧制在实用水平上实现厚度偏差校正效果，将N的次数的下限值取为1。另一方面，增加次数N越多，厚度偏差改善率越高，例如有必要延长卷II的辊部III的主体长度，以便使次数 N为20以上，以确保厚度偏差改善率> = 90％。此外，由于担心轧制强度相对于轧制负荷的降低，实际上将上限值设定为N，将上限值设为15，这是基于高可以提供从未有过的准确性。
