Liquid Steel Temperature Measurement Based On Infrared Image Processing Technology

At present, Adopt the method which controls liquid steel temperature accurately is a new research hotspot in the field of metallurgy. The current application of molten steel temperature measuring methods can not be real-time and achieve the temperature of liquid steel rapidly. Looking for a new steel measuring method is imperative,based on the theory of infrared temperature measurement method, to set up a real-time infrared measuring temperature of molten steel temperature on-line monitoring system.Steel infrared temperature measurement system by thermal imager to accept of the infrared radiation energy of molten steel, on the computer infrared radiation energy is converted into the corresponding steel thermal infrared images, With a steel infrared measuring temperature of molten steel thermal infrared image processing software,steel hot like figure corresponds to the grey value and temperature can be obtained.In image denoising processing, the impact of the noise eliminate the main maximum and through the image quality assessment parameters, before and after image denoising effect is compared. Denoising method, through the wavelet threshold denoising of molten steel noise is reduced in the infrared thermal image, then according to the relationship of temperature and gray, the temperature can be obtained in Matlab.Software aspects, steel processing of infrared measuring temperature interface is designed with the feature of VB and Matlab. It includes thermal image noise denoising and molten steel temperatureLots of measurement verification of the experiment indicate that molten steel temperature error in infrared temperature measurement system is small and it can achieve the basic conditions of actual steelmaking production and scientific experiment...
