THE RESEARCH OF DUST FORMATION DURING THE ARC HEATING OF METALS
https://doi.org/10.17073/0368-0797-2014-3-3-9
Abstract
The intensity of iron evaporation was studied depending on the current strength and time of arc effect on metal in a laboratory furnace. The effective melting temperatures and temperatures of the liquid metal surface in the arc core have been calculated at different evaporation rates. The study includes the estimate calculation of the specific dust formation in a DC arc furnace. The experimental calculated data are related to evaporation of liquid iron, whereas melting process, the composition of metal, the presence of slag make the significant influence on dust formation under the arc effect. These data are consistent with industry values of specific dust formation at accepted assumptions.
