Claim 1
Independent Claim
163 words
DEVICE FOR THE CONTINUOUS MEASUREMENT OF THE OXIDE SATURATION TEMPERATURE OF A LIQUID METAL, SAID DEVICE COMPRISING A CONDUIT FOR THE CIRCULATION OF LIQUID METAL WHICH IS PARTIALLY OBTURATED AT ONE POINT BY A PERFORATED PLATE, CHARACTERIZED IN THAT SAID CONDUIT COMPRISES AN ECONOMIZER CONSISTING OF TWO COAXIAL TUBES WHEREIN ONE TUBE IS AN OUTER TUBE FOR THR ADMISSION OF HOT LIQUID METAL AND THE OTHER IS AN INNER TUBE FOR THE DISCHARGE OF COOLED METAL LIQUID WHICH HAS PASSED THROUGH THE PERFORATED PLATE, A COOLING UNIT PLACED AROUND SAID ECONOMIZER IN THE VICINITY OF THE PERFORATED PLATE, A THERMOMETRIC ELEMENT FOR MEASURING THE TEMPERATURE OF LIQUID METAL ADJACENT SAID PLATE, A FLOW METER FOR MEASURING THE RATE OF OUTFLOW OF SAID METAL AND MEANS FOR MEASURING THE RATE CONTROLLING THE COOLING UNIT IN DEPENDENCE ON A CONSTANT VALUE OF THE FLOW RATE AND IN DEPENDENCE ON A STABLE PARTIAL PRECIPITATION OF THE OXIDE OF THE METAL WITHIN THE PERFORATION OF SAID PLATE.
