METHOD AND SYSTEM FOR THE END-OF-CAST CONTROL IN A BLAST FURNACE OPERATION

Abstract

The invention relates to a method and system of controlling the end-of-cast of a tapping operation in a metallurgical furnace, preferably in a blast furnace, the method comprising: initiating a tapping operation by tapping liquids from at least one taphole in a metallurgical furnace; receiving acoustic signals from the tapping operation in at least one acoustic receiver located remotely from the taphole; converting the acoustic signals received by the least one acoustic receiver into electrical signals, the electrical signals corresponding to acoustic signals transmitted by the tapping operation and sensed by the acoustic receiver; processing the electrical signals to determine if an acoustic event in relation to the tapping operation has occurred by comparing the electrical signals with pre-determined tapping operation conditions; generating indication data, depending on the comparing; providing an indication based on the indication data; and initiating an action in relation to the tapping operation using the indication data.
