ABSTRACT:
A method for improving the making of metals such as steel and copper by specially using a gas measurement system to analyze molten metals for gas, particularly H2 content, and to controlling the metal making process based on these values. The preferred gas analyzer comprises a hollow probe and an analyzer wherein the probe is immersed in the molten metal and a carrier gas containing a reducing gas such as CO is cycled through the probe and analyzer. The carrier gas entrains gases in the probe and this gas mixture is electronically compared with a reference value to provide a measurement of the gases in the molten metal and the process is controlled based on the analyzer results. Another important use of the gas analyzer is in molten metal degassing operations such as used in the steel
