Abstract
A method is disclosed for improving the making of metals such as steel and copper by using a molten metal gas measurement system to measure the gas content of the molten metal particularly H.sub.2 content, and to controlling the metal making process based on the gas content value. The preferred gas analyzer comprises an improved long lasting immersion probe body and an analyzer wherein the probe body is immersed in the molten metal and a carrier gas is cycled through the probe and analyzer. The carrier gas entrains gases diffusing into or formed in the probe body 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 industry. The improved probe body is preferably made from refractory mortar which is formed into a paste mixture with water, molded, and cured to form the probe body product.
