Improvement of the Technology of Melting of Low Alloy Steel Alloy in an Electric Arc Furnace

Abstract:

This article presents the optimal method of melting the 35XGCL (analog is JIS G 5111) low alloy steel alloy in DSP-2.0 2000 kg electric arc furnace. All the main stages of melting in an electric arc furnace are considered. In addition, analytical data on the study of the slag mode during the fluidization of the alloy are presented. The results of the evaluation of oxygen activity in metal depending on the chemical composition of slag oxidation and reduction cycles in the furnace are presented. Graphs of oxygen activity in the alloy depending on the total amount of iron, silicon, and manganese oxides in the slag are presented. Moreover, the effect of constant and additional deoxidizing aluminum content in the alloy on the impact strength of low alloy steel alloy is presented. The impact strength is improved when the constant aluminum content is in the range of 0.05-0.07%.
