Abstract

It is assessed the transfer of chromium, manganese and carbon of different agglomerate fluxes constituted by 18.75 % of alloyed load and 81.25 % of matrix during the SAW process (Submerge Arc Welding). A vitreous basic matrix corresponding to the system SiO₂-Al₂O₃-(CaO+MgO) was obtained from minerals by fusion in the electric arc furnace. The current proportions of the alloyed load components (FeCr, FeMn and graphite) were carried out using a McLean Anderson experiment design. The corresponding fluxes to each experimental point were obtained by granulation with liquid glass; afterwards, their transfer coefficient for a given regimen of welding was determined. The transfer coefficients were calculated by means of a formula based on the laws of mass conservation and of distribution.
