By establishing necessary thermodynamic conditions in contacting phases one may regulate migration of nitrogen in the triple system gas-slag-metal [17], whereby the conditions are ensured by deoxidation of slag and the metal by strong deoxidizers as it was registered in the process of our meltings in graphite crucibles.
In the steel casting industry, aluminum is universally used as a final deoxidizer. The deoxidation products are [Al.sub.2][O.sub.3] and hercynite ([FeO-[Al.sub.2][O.sub.3]).
In the present study, an agglomerated cost-effective acidic flux was developed by using the flux dust of the parent flux with addition of potassium silicate as binder and aluminium powder as deoxidizer. The two butt-weld joints were made with mild steel as the base plate and backing strip.
In addition, aluminum (Al) is generally added as the deoxidizer in steelmaking.
The flux is burnt by the heat of the flame; the smoke produced thereof acts as deoxidizer which protects the weld puddle from contact with the environment.
Since the STS-refining process used aluminum as a deoxidizer to remove oxygen frommolten steel, SRS had a high content of [Al.sub.2][O.sub.3] (oxygen affinity: K > Ca > Mg > Al > Ti > C > Si > Mn > Cr > Fe > Ni > Cu).
Flux acts as a deoxidizer and prevents the formation of porosity in the weld pool.
This layer was overlay welded by mixture containing glass powder which silicon acted as deoxidizer. Higher hardness (61 HRC) of second layer alloyed by chromium was obtained after tempering at 550[degrees]C temperature.
(13) Characterization of this type of conversion coating (14,15) with a chromate-based deoxidizer treatment (16,17) has been reported previously, as well as the filiform corrosion resistance.
Low concentration of the main deoxidizers requires for increased attention to oxidation of the metal.
Formula XL[R]-550 gas-shielded flux-cored wire delivers X-ray quality welds in all positions and features added deoxidizers that cut through light rust and mill scale with minimal pre-cleaning.
