Apparatus for the determination of a parameter of a molten metal or a slag layer on the molten metal

摘要

A carrier tube (2) with a measuring head (3) is arranged on lance (1). An analog to digital (A/D) converter (11) is connected to a sensor such as oxygen sensor (5), temperature sensor (6) arranged within the measuring head. The measuring head has contact piece (14), which is electrically connected through the contact terminals (13) to a signal output of the A/D converter. The signal lines (12,16) within the lance are connected to A/D converter through contact terminals and to a computer or analysis device (17). An independent claim is included for molten metal parameter measuring system.
