Problems solved by technology
[0003] At present, there is still no effective detection method for the temperature and spectrum online continuous detection in the ultra-high temperature environment (above 1600°C) steelmaking furnace, because there is no light-guiding medium that can withstand the high temperature in the furnace to transmit the spectral information in the furnace, and The temperature and spectral information obtained through the test of the observation port outside the steel furnace are often rich in the interference of factors such as water vapor, smoke and plasma flashes in the steelmaking process, and cannot accurately measure the temperature and spectral information of molten steel

Description
technical field [0001] The invention relates to the field of temperature measuring equipment, in particular to a device and method for continuously measuring temperature and spectrum in an industrial furnace. Background technique [0002] At present, the temperature of the molten steel in the steelmaking furnace is mainly measured intermittently by thermocouples, and the composition of the molten steel is analyzed by sampling and then off-line to detect the composition of the molten steel. The continuous on-line measurement of the molten steel temperature in the steelmaking furnace is of great significance for realizing the intelligent and automatic control of the steelmaking production process and improving the quality of steel. At the same time, real-time online monitoring of the molten steel spectrum in the steelmaking furnace is also of great significance for realizing intelligent control of steelmaking production and improving steel quality. Through the extraction and ...
