Abstract

Formation of iron-carbon melts is governed by carbonization of liquid metal (semiproduct) in modern steelmaking technology. Changes in structural condition of liquid melt show dynamics and results of melt formation before equilibrium state. Kinematic viscosity is considered as a structural-sensitive property of melt. New data on the relation of melt oxidization, melt formation dynamics and sulphur concentration are presented in this paper. It is shown that negative influence of impurities is sufficient at comparatively low content ([O] > 8 ÷ 10 ppm, [S] > 1 ÷ 2 ppm). Principle of complex carbonization and deep refining of melt is proposed on the basis of laboratory experiments.
