Phase level system

Abstract

System to determine the height in liquid or molten metal levels or phases within a mat or slag converter or pyrometallurgical furnace, whereby it comprises a signal generator and a signal processor, where such generator sends an electrical signal to such processor, being such processor connected to a group of electrodes placed in the converter's shell or pyrometallurgical furnace, in which such electrodes are disposed crossing the shell in electrical contact with the phases so that they are installed in height zones of the slag and metal levels or phases, so that once such electrodes are installed configuring serial resistance groups through which such electrical signals circulate.

1 . System to determine the height in liquid or molten metal levels or phases within a mat or slag converter or pyrometallurgical furnace, whereby it comprises a signal generator and a signal processor, where such generator sends an electrical signal to such processor, being such processor connected to a group of electrodes placed in the converter's shell or pyrometallurgical furnace, in which such electrodes are disposed crossing the shell in electrical contact with the phases so that they are installed in height zones of the slag and metal levels or phases, so that once such electrodes are installed configuring serial resistance groups through which such electrical signals circulate.  
   
   
       2 . System to determine the height of phases according to  claim 1 , whereby a set of electrodes is installed above a certain phase level and another set of electrodes is installed under such phase level.  
   
   
       3 . System to determine the height of phases according to  claim 2 , whereby, each electrode set is composed by at least two electrodes in case the determination of phase heights is discrete.

       8 . Method to determine the height of liquid or molten metal within metal, mat or slag converters or pyrometallurgical furnaces whereby the method consists in measuring the electric resistance of such liquid metal and/or slag phases present in such converter or pyrometallurgical furnace, so that through the differences in such electric resistances detected in each phase the height in which each one of the is places is determined; in that such measurement consists in determining the potential fall between a group of electrodes placed at different heights in the shell of such converter or furnace, being such electrodes submerged in contact in such phases, and conforming a serial group of resistance, by which through such electrodes a circular current is made to circulate, such current coming from a signal generator system and modulated by a signal processor, so that once such current circulates, the electric resistances of the regions comprised between such electrodes are inferred, so as to obtain a real time measurement of the height levels of such phases inside said converter or furnace.

       10 . Method to determine the height of phases according to  claim 9  whereby the measured resistance is obtained by the electrode resistance plus the wire resistance, through which such resistances are connected, plus the resistance phase.
