Some Perspectives on the Quest for Steel Quality

抄録

Improvements in steel quality are strongly dependent on elimination of "unsought variations" in chemistry, temperature and fluid flow of metal, slag and gas phases within, and during transfer between, the ladle, tundish and mold. As we move toward the next century it is imperative that we not only prevent "unsought variations" during processing but also develop on-line sensor technologies which will permit us to continuously monitor and thus detect at an early stage, the occurrence of any "unsought variations" due to perturbations or imperfections within the processing system.
