The article introduce the process of Electric Arc Furnace with Dephosphorized hot metal charging for melting stainless steel in Baosteel stainless steel Branch. Based on the practice of production, The main factors affecting the process of EAF with De-P HM charging are theoretically analyzed, such as using oxygen, the material charging and making slag. The optimization of hot metal charging can advance the use of chemical and physical energy, reduce the consumption of power. The optimization of using oxygen can increase the use of chemical energy. The optimization of material charging can reduce the oxidation of Cr. Making foamy slag can advance the transformer capacity and the use of power. Based on the character of the process EAF with De-P HM charging for Melting Stainless Steel, EAF productivity increased were reached with application of integrated control theory on EAF process in Baosteel stainless steel branch.

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.

This research aims to study the process of incorporation of the metal iron contained in electric arc furnace dust (EAFD), by addition in hot metal at a temperature of 1,400 degrees Celsius altering experimental conditions such as how to add the EAFD (“as received” and in the form of briquettes), the percentage of EAFD to be added (10, 20 and 30% of initial weight of sample pig iron). The time of withdrawal of the sample of pig iron and slag (30 minutes after the addition of EAFD). Previously, the EAFD will be characterized using the following techniques: chemical analysis, particle size analysis, X-ray diffraction, scanning electron microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) microanalysis. After characterization, the electric arc furnace dust to be added to the bath of liquid iron, will be divided into 2 types: the first order of addition will be in the form "as received" from the plant and the second is through the agglomeration of EAFD in the form of briquettes. The achievement of fusion experiments in laboratory scale will take place in a vertical tubular furnace with temperature control. The fusion experiments to assess the incorporation of the metal iron will use graphite crucibles. A flow of inert gas (argon) will be maintained inside the furnace during the experiments. It is expected that the results obtained at the end of the research allow the evaluation of the iron metal incorporation of electric arc furnace dust in pig iron bath.

This research aims to assess the incorporation of mass of the electric arc furnace dust (EAFD) by addition in hot metal produced in a local foundry (1.78% Si) at a temperature of 1,350°C. The EAFD is from a steel mill producer of long steel. The EAFD was added in the form of briquettes. Previously, the EAFD was 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, took place in a vertical tubular furnace with temperature control. The fusion experiments to assess the incorporation of the EAFD mass used alumina crucibles. A flow of inert gas (argon) was maintained inside the furnace during the experiments. After cooling the furnace to room temperature, it was done the pig iron and the slag were weighed to do a mass balance to assess the efficiency of the experiments.
