Melt properties change depending on the composition of charge in manufacturing of insulation fiber

The article provides the results of the study of rock melting process in an electromagnetic plasma arc reactor in order to obtain fusions and heat-insulating fiber. The authors analyze the design features on the example of the reactor’sscheme. This allowsgetting it relatively clean, free from the recovered metals. Operating modes of the plasma reactor with fixation of a temporary component, temperature and the volt-ampere characteristic are considered in the research. The work provides the analysis of themelts’ characteristics that are crucial in the production of heat-insulating fibers, depending on the composition of the charge, taking into account the features of the reactor. We present the spectrogram and the composition of dunite and dunite-basalt charges, as well as the spectral lines of the elements' distribution and their mass concentrations. We also provide the analysis of the results of spectral analysis of these charges.
