Manufacturing of New Welding Fluxes Using Silicomanganese Slag

[摘要] There were developed the composition and manufacturing technology of new welding flux using industrial products such as slag of silicomanganese production. The effect of fractional composition on welding and fabrication characteristics was studied. It was found that using of small-sized fracture of welding flux at a rate of 30-40% decreases the oxide non-metallic impurity rating of the weld and herewith doesn't affect its constituents. To increase technical-and-economic indexes it was suggested to mix small-sized fracture and water glass. The use of ceramic flux made by mixing the dust fraction of silicomanganese slug with fraction size less than 0.45 mm and water glass provides the decrease of non-metallic impurity rating of the weld. Herewith the increase of its content from 15 to 40% doesn't have a significant influence on the non-metallic impurity rating of the weld and its constituents.
