Monitoring concentration of molten bath components

摘要

A method for monitoring concentration of components in a molten bath includes providing a molten bath wherein the bath has a known concentration of the component at a given feed rate of a feed into the molten bath. For example, methane and hydrogen gas concentrations can be measured in off-gas released by a molten metal bath. The measured amounts of the methane and hydrogen gas can be correlated with known amounts of methane and hydrogen gas for a given concentration of carbon in the molten metal bath at steady state conditions, thereby monitoring the concentration of carbon in the molten metal bath.
