Device for measuring temperature of molten metal bath using optical fiber
A recently granted patent (Publication Number: US11959813B2) discloses a device designed for measuring the temperature of a molten metal bath. The device comprises an optical cored wire with an optical fiber partially surrounded by a metal tube, a second tube with specific dimensions, and gas-permeable separating elements between the optical cored wire and the second tube. These elements allow for the movement of gases and are filled with a gas or gas mixture. The optical fiber receives thermal radiation from the molten metal bath and conveys it to a detector for temperature measurement. The second tube is made of a material with high thermal conductivity, such as iron or alloyed steel, ensuring efficient heat transfer for accurate temperature readings.
Furthermore, the patent includes claims related to the arrangement of separating elements within the second tube, the materials used for these elements, and the density range of the device. The patent also describes a system incorporating this device and a method for measuring the temperature of a molten metal bath using the device. The feeding rate of the device into the molten metal bath is specified, along with the temperature measurement process. Overall, the patented device offers a precise and reliable solution for monitoring the temperature of molten metal baths in industrial settings, with specific design features aimed at enhancing performance and accuracy in temperature detection.
