Improvement in steel smelting by studying melt behavior

摘要

Analysis shows that the disequilibrium of melts may be used to characterize metal quality and to optimize smelting technology. For the production of pipe steel by means of a superpowerful DSP-135 arc furnace, a ladle-furnace unit, a vacuum-treatment system, and a continuous-casting machine, the sources of melt disequilibrium are studied in relation to the properties of the final steel. That provides the basis for the development of parameters characterizing different stages of the process. The proposed improvements in smelting technology are shown to be very efficient. © 2013 Allerton Press, Inc.
