Molten Metal Gas Sampling |
摘要 |
Apparatus and methods for simultaneously testing molten metal, such as steel, for concentration of three or more dissolved gases. A gas flow manifold allows multiple calibrations of a gas analysis device independently of operations such as immersion and purging of an immersible probe that can be provided with a bypass conduit for gas flow directly to the analysis device. Accurate nitrogen content is determined by oxidizing a retrieved gas sample using heated CuO and measuring gas concentration of the gas before and after such oxidation. A gas reservoir can be used to temporarily store a portion of the retrieved gas for use in such testing.
