Abstract
The present invention relates to a method and a system for determining a temperature value of a molten metal bath. The method according to the invention has been proven to be especially suitable for installations of metallurgical vessels which are constantly moved during the metal making process.
Claims15
A method for measuring the temperature of a molten metal bath in a furnace with a device comprising an optical cored wire and a detector, wherein the furnace has a furnace inclination, the method comprising
- (a) providing a set of data relating furnace inclination values Fl to corresponding measurement profiles MP;
- (b) determining a furnace inclination value Fl(n) for a point in time t(n);
- (c) choosing a measurement profile MP(n) corresponding to the furnace inclination value Fl(n) from the provided set of data relating furnace inclination values Fl to corresponding measurement profiles MP;
- (d) applying the measurement profile MP(n) at a point in time t(n) to obtain a measured temperature value.
A system for determining a temperature value of a molten metal bath in a furnace, a processing element P1 for determining a furnace inclination value Fl;
- a processing element P2 for choosing a measurement profile MP(n) corresponding to a furnace inclination Fl(n) from the provided set of data relating furnace inclination values Fl to corresponding measurement profiles MP;
- and
- wherein the controlling unit C comprises:
- a controlling element C1 for applying the measurement profile MP(n) to obtain a measured temperature value.
