System - SiO2 MNO Molten Flux for submerged arc welding

摘要

The present Invention relates to the Metallurgical Industry, and in particular to obtain a FUSED Flux System - a relationship with SiO2 MNO MNO / SiO2 = 1.36-1.43 and presence, as Modifiers, Cao in the range 0 - 4.4%, Al2O3 in the range 0 - 3.6% and CaF2 in the range 4.5-9%. Presents a basicity and activity 0.74-80 0.59-0 B = and =.67, respectively, thermodynamic activities of MNO and SiO2 of amno-0.0255-0.0292 and asio2-0.2270-0.2707 and biscosidad between 0.15 and 0.3 pa.s. Vitreous Brown Dark Flux obtained by Melting and Pouring water for granulation, with excellent performance. Plastic and metal in the welding of Carbon Steel, Low Alloy.
