Process Control Research Summary


Recent work shows that modern optical techniques, in conjunction with atomic and molecular spectroscopy, are valuable tools for on-line control of the Creusot-Loire-Uddeholm converter for alloy steelmaking. The optical technique has been closely investigated in relation to the reduction step of the process, and the resultant observations point towards a variety of applications in several steelmaking processes.
