Experimental Designs towards an Understanding of Process Phenomena in Steel Making

摘要

The present paper demonstrates the importance of proper experimental studies to understand different process phenomena. A number of experimental designs directed towards the understanding of different process phenomena in iron and steel making is presented, i.e.: 1. the graphitization of coke studied by thermal diffusivity measurements as well as x-ray diffraction in static and dynamic modes, 2. the reduction sequences of iron ore pellets monitored by x-ray image analysis, 3. the bubble formation due to two-phase reactions studied by suitably designed water-model experiments, 4. the foaming phenomena under dynamic conditions monitored by the x-ray technique after suitable experimental arrangement, and 5. the melting of mould fluxes investigated by novel designing of the experiment.
