The temperature measurement and sampling system uses industrial robots as the platform, combined with robot application technology, detection technology, and robot visual recognition technology to complete the robot’s automatic installation of probes. The automatic measuring gun with the probe extends into the high-temperature molten steel for temperature measurement or sampling, and the probe is automatically removed Function, and flexible automatic action, strong adaptability to environment and working conditions, strong safety, stable measurement results, easy maintenance, easy to learn and easy to use. After this system is online, it can improve the accuracy of molten steel temperature control and reduce human interference, which is of great significance for improving the control ability of molten steel heat, improving molten steel quality, and reducing labor intensity of workers.
