Description of the Invention: [Technical Field] The present invention relates to a method for measuring the configuration of a device, and a method for measuring the configuration of a rust removing device. [Prior Art] In the prior art, the problem of the scale is directly the main factor of the surface quality of the product. For example, in a hot/cold rolling process, dry skinning can cause surface defects in hot/cold products, and improvements in rolling defects are closely related to the de-recording device and its ability to remove. The main function of the de-recording device is to correctly guide the high-pressure de-recording water from the high-pressure pipeline to make it work smoothly and remove the high-temperature skin that is generated during the high-temperature heating operation on the surface of the hot-rolled steel strip, thereby avoiding being trapped due to residual skin. The post-rolling mill is rolled into the skin to cause defects in the filming. On the contrary, if the configuration of the de-recording device is not good or the relative position of the sputum in the de-recording device is offset, the surface of the steel strip will be formed with a de-recording situation such as a depletion zone or a weakened zone, thereby reducing the de-recording of the de-recording device. The ability to form a roll into the skin and lack of heart 'reduced the surface quality of the steel strip. In addition, in the conventional technical order, because the volume of the descaling device is too large and the hot rolling mill is limited to the space, it is extremely difficult to make the measurement reference and positioning settings, and 'there is a method for measuring the critical dimensions of the de-recording device. , the benefit method obtains the geometric dimensions such as the distance and angle after the installation of the de-recording device and the nozzle, so the nozzle welding is not easy to locate and f control. 1 The hot-rolled steel strip case has its own raw materials, such as coffee, 250 La, and 27 (). Different factories ^: The above-mentioned de-recording device and the geometry of each distance and angle after nozzle installation have a crucial impact on the subsequent de-recording, because there is no reliable 147062.doc 201229457 stem measurement method, so that the flat The influence of the thickness of the steel blank and the descaling device on the derusting ability and the change are also not evaluated, so even if the nozzle is offset, the actual offset cannot be obtained. Therefore, it is necessary to provide an innovative and progressive descaling device configuration measurement method to solve the above problems.
