Abstract:
In a method for the early recognition of ruptures in continuous casting of steel with an oscillating mold composed of copper plates, by carrying out continuous and comparative first and second measurements of a temperature distribution with respect to location in the copper plates and a temperature distribution with respect to time in the copper plates, and by analyzing the obtained measurement data, wherein, for increasing the probability of a precisely targeted evaluation of indications of an acute rupture tendency, coupling the first and second measurement data to be compared to each other as well as to measuring data of at least a third row of measurements, and analyzing the coupled measurement data, the improvement comprising measuring by means of the at least one third measuring row a partial frictional engagement between the mold and a cast strand in accordance with an efficiency of lubrication by carrying out a comparative measurement of a mold oscillation and a strand oscillation underneath the mold, and coupling the measurement data together with the measurement data from the temperature distribution and a distance/time behavior of the mold and analyzing the result by computation.
