1.前言以往,铜及铜合金无缝管的管壁厚度和管壁的均匀厚度测量,多数情况下是用千分尺在停止生产线作业时进行的,且只能对管子的端部进行测量。由于用这种方法无法保证整个管长的质量,效率十分低。从保证管子的质量及省力两方面考虑,人们期望进行自动化测量。作为自动测量的方式包括射线和超声波(旋转或多通道式)二种。这二种方式从价格和操作方面考虑都有一定的问题。为此,提出利用脉冲反射法的超声波三点测量的方法对管子的全长厚度进行测量。这种方法便宜且操作方便,由实验装置确认这种方法是有效的。本文摘要介绍了这种方法,并
1. Introduction In the past, copper and copper alloy seamless pipe wall thickness and wall thickness measurement, in most cases is to use a micrometer to stop the production line operation, and only the end of the pipe to measure. As this method can not guarantee the quality of the entire pipe length, the efficiency is very low. From the perspective of ensuring tube quality and labor saving, one expects to make automated measurements. As a means of automatic measurement of radiation and ultrasound (rotary or multi-channel type) two. Both of these methods have some problems in terms of price and operation. To this end, the use of pulse reflection method of ultrasonic three-point measurement of the total thickness of the pipe to measure. This method is cheap and easy to operate. It is validated by the experimental setup that this method is effective. This article summarizes this approach, and
