主要介绍了梅山热轧板厂使用的RM312 X射线测厚仪的立体测厚原理。对RM312C形架内部主要部件、带钢边缘位置的计算方法、横向测量点梯度和高度以及横断面厚度的计算方法进行了介绍,并对RM312的测厚性能作了分析。RM312 X射线测厚仪通过使用立体测厚技术可以对带钢横断面厚度进行快速准确的测量,而且还具有测量带钢宽度、平直度等功能。
The principle of thickness measurement of RM312 X-ray thickness gauge used by Meishan Hot Rolling Mill is introduced. The main components of RM312C frame, the calculation method of strip edge position, the method of calculating the gradient and height of transverse measuring points and the calculation of cross-section thickness are introduced. The thickness measuring performance of RM312 is also analyzed. RM312 X-Ray Thickness Gauge Thickness of the strip can be quickly and accurately measured by using the Thickness Gauge technology. It also measures the strip width, flatness and other functions.
