UNIQUE EXPERIMENT ON THERMAL DIFFUSION OF ELEMENTS IN LIQUID CAST IRON

Abstract
The melt temperatures and the maintenance of elements (C, Si,
Mn, S, P) are given in various levels of a blast furnace. Uniqueness of this experiment is that, unlike laboratory installations, the real conditions of a blast furnace created ideal thermal insulation of liquid melt on all directions and thermal diffusions of elements (C, Si, Mn, S, P) in the vertical direction. From these experimental data the authors have calculated thermodiffusion heat of cast iron melt elements and have shown that carbon, silicon, manganese and phosphorus, both in the liquid and solid metal, move towards the hotter parts of the system, and sulfur, conversely, towards the colder. This conclusion can
be used at the description of existing and creation of new processes of metal desulfuration.
