Abstract

A series of experiments has been conducted on commercial open-coil annealing facilities to investigate the effects of process variables on the decarburization of steel. A solid electrolyte oxygen probe using iron+iron oxide as a reference electrode has been developed for monitoring furnace atmosphere. This is shown to be a valuable tool in optimizing the decarburization process. By combining high gas flow rates with high dew point, it was possible to effect a significant reduction in the time required for open-coil decarburization.
