The invention discloses a method and device for measuring the surface temperature distribution of continuous casting slabs. The method comprises the following steps: acquiring an infrared image of the slab; correcting the infrared image; identifying the slab target in the corrected infrared image, and Obtain infrared temperature values corresponding to multiple temperature measurement points on the target surface of the slab; obtain the temperature distribution of the slab surface according to the multiple infrared temperature values. The invention is easy to implement, can conveniently realize the non-contact slab temperature measurement, can accurately measure the temperature distribution on the surface of the slab, and is beneficial to provide accurate and reliable information for various application scenarios such as continuous casting production on-line control and slab quality analysis. Data support and guidance, high universality and reliability.
Description
technical field [0001] The invention relates to the technical field of metallurgical continuous casting production, in particular to a method and device for measuring the surface temperature distribution of continuous casting slabs. Background technique [0002] In the process of iron and steel smelting and continuous casting, accurate and continuous measurement of the temperature of the slab is an important link in the quality control of the slab production. Since the slab crystallization process in continuous casting production, the material properties of the final product, and the energy consumption level of continuous casting smelting are closely related to the slab temperature, it is of great practical value to conduct a complete, continuous and accurate measurement of the slab temperature . [0003] There are two main ways to measure the temperature of slabs currently used in production: [0004] 1) Manual sampling method: use a point temperature measuring gun to ran...
