Study on Detecting Technology for Slight Signal on Crack Forecast in Continuous Casting
As we known, It is very important that the checking of crack in the production of continuous casting billet. Usually we use the method of checking the temperature of the crystallizer. But the temperature fluctuation of the crystallizer is hard to be checked when the crack appears, so an appropriate method to deal with this problem must be studied. This paper briefly discusses the picking-up method for those slight signals — —temperature from the thermocouples around the crystallizer that check the temperature fluctuation, because of those slight signals in the crack checking of the continuous casting billet might be submerged in noise entirely. It analyses the difference between the signal and the noise on the time and the statistics, and introduces a kind of effective detecting method, applying the correlation function to pick up the slight signal submerged in noise entirely.
