Non-Contact Temperature Measurement System of Molten Steel in LF Furnace and Its Application
Temperature control plays an important role in LF refining process, which is the key to control the quality of molten steel composition, continuous casting quality and stable process. A non-contact molten steel temperature monitoring system is developed. The system can obtain the real-time and high-clear heat image of molten steel in LF furnace through a dual optical path area array CCD detector, and then processes the image information by computer, so as to accurately identify the molten steel and calculate the real-time temperature data according to the temperature measurement model. The system can also be used as industrial TV, which is convenient for steelworkers to know the conditions in the LF furnace in time. Different from the previous contact temperature measurement methods, the new system can measure the molten steel temperature in LF furnace in real time without affecting the smelting progress. It is convinient and safe to operate, which isa technology worthy of promotion and also has a guiding role in other temperature measurement application fields.
