Popis: | The softening and melting characteristics off some pellets and sinter during the reduction and the heating were examined by using an X-ray TV apparatus. The structure of the samples after the experiment were also examined by a microscope and an electron microprobe analyzer.For the runs without load, the melt-down temperatures varied from 1250°C to the melting point of iron according to the reducing conditions and rose with the increasing reduction degree.An application of load lowered the melt-down temperature of each sample, which strongly depended upon the properties of the formed slag.The EPMA analysis shows that the slag containing a small amount of iron oxide is formed in Hirohata P. of high melt-down temperature, but much iron oxide, about 50%, is contained in the slag formed in Robe River P., which melts at a low temperature. |
