Abstract
Pyrogenic processes in which gas or fume is evolved are monitored by impinging a beam of X-rays (3) from an X-ray source (1) on the gas or fume whereby radiation is produced by the X-ray fluorescence which is detected by a radiation detector (7) and analyzed by an analyzer (8) for the various constituent elements. In this way the progress of the metallurgical process can be monitored and the information used for process control.
