Determination of the fundamental softening and melting characteristics of blast furnace burden materials
- Delft Univ. of Technology (Netherlands). Faculty of Mining and Petroleum Engineering
An experimental technique to investigate the fundamental mechanisms taking place on a microscale in the softening and melting zone in the blast furnace, is presented. In the present paper, attention is focused on determination of the softening viscosity of porous wustite. The technique may be potentially useful to investigate more complex samples of ironbearing material, as occurring in the blast furnace. In comparison with the results obtained by other researchers the viscosity of porous wustite found in the present work is substantially higher than reported elsewhere for sinter and pellets. This may be an indication that softening is not merely a reflection of the solid state deformation under load of wustite. An important factor may be local melting of some of the phases present within the sinter and pellet structures.
