大直径热轧钢管测径仪的热标定与检测精度

    HOT-GAUGING AND MEASUREMENT ACCURACY OF CALLIPERS FOR LARGE DIAMETER HOT-ROLLED STEEL TUBE INSPECTION

    • 摘要: 介绍了大直径热轧钢管测径仪的热标定方法。实践证明,采用热静态测量加温度补偿的方法,较好地解决了测径仪的标定,满足了测量精度要求。

       

      Abstract: Described in the article is the hotgauging of callipers for inspection of large diameter hotrolled steel tubes. The site operation result shows that better gauging and satisfactory measurement accuracy of the said callipers can be achieved by means of thermal static measurement plus temperature compensation.
