Evaluation of the Addition of Electric Arc Furnace Dust in Hot Metal Changind the Type of the Crucible
Abstract:
This research aims to assess the incorporation of mass of the electric arc furnace dust (EAFD) by addition in hot metal (1.78% Si) at a temperature of 1,400°C changing the type of the crucible. The EAFD is from a steel mill producer of long steel. The EAFD will be added in the form of briquette. Previously, the EAFD is going to be characterized using the following techniques: chemical analysis, size analysis, X-ray diffraction, scanning electron microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) microanalysis. The achievement of fusion experiments in laboratory scale, is going to take place in a vertical tubular furnace with temperature control. The fusion experiments to assess the incorporation of the EAFD mass are going to use three kinds of crucibles. After cooling the furnace to room temperature, it will be done the hot metal and the slag weighing to do a mass balance. A flow of inert gas (argon) is going to be maintained inside the furnace during the experiments.
