    ABSTRACT. Is carried out the thermodynamic estimation of the probability of the flow of the processes of the removal

    of hydrogen from the weld with the welding in the fluorine-bearing flux in the standard states in the range of

    temperatures 1700 2200 K. In this case, as the standard states for the substances of reagents they were selected:

    Na3AlF6L, SiO2L, SiF4g, NaAlO2s, Na2SiO3l, CaF2l, CaSiO3l, H2g, SiF2g, HFg, O2g, SiFg, Hg. As a result the calculations of

    standard energy of Gibbs and equilibrium constants of reactions it is determined, that from the reactions of the direct

    interaction of ftoragentov of slag with hydrogen and oxygen of the metal most probable appears the reaction with the

    cryolite. In the mechanism of more complex interaction with the participation in the reaction, besides ftoragentov, silica

    of slag and by the possible formation of the intermediate product of SiF4g more probable is the process with fluorite.

    Calculations showed the expediency of using the connection Na3AlF6 together with fluorite for the removal of hydrogen

    with the submerged welding. The carried out calculations became the basis of the development of the compositions of

    the new flux- additives, protected by patents RF.

    Introduction. The issue of new fluxes and their additives development has been attracting much

    attention currently, as well as research into their influence on welding and technological characteristics

    of a weld and on the concentration of oxygen and non-metallic impurities in a weld [1-5].

    Submerged arc welding is attended by intensive mass transfer of liquid molten metal and slag,

    forming from welding flux. Reactions of oxidation and deoxidation of manganese, ferrum, and

    silicon, i.d. exchange processes involving oxygen are typical for this process. The most grades of

    domestically produced fluxes, which are applied for welding low-alloyed steels are oxidizing ones

    and ground on silicon-manganese oxidation-reduction processes. Here, the products of these

    reactions are oxide compounds of silicon, manganese, ferrum, aluminum etc., which often cant

    surface and assimilate to slag, forming from welding flux, the level of impurity of weld metal by

    non-metallic admixtures increases consequently; as the result, the complex of physical and

    mechanical characteristics deteriorates. Apparently, restoratives, which form gaseous products of

    reactions, are advisable to apply in order to avoid impurity of weld metal. It is carbon that can be a

    restorative of this kind, and forms gaseous compounds CO2 and CO when reacting with oxidizers.

    Materials and methods of research. Shielding is usually provided through pushing atmospheric

    gases aside from weld zone by forming gases CO2 (CO); that helps to reduce or even exclude the

    probability of molten metal saturation with oxygen, nitrogen or hydrogen from atmosphere. Gas-

    forming compounds of carbonates like CaCO3, MgCO3, FeCO3, MnCO3 and their derivatives are

    usually used for this purpose. Gas shielding is possible due to CO2 as high-temperature

    decomposition of carbonates takes place according to the following reactions and temperatures [6]:

    CaCO3 CaO + CO2 (900-1200 C), (1)

    MgCO3 MgO + CO2 (>650 C), (2)

    FeCO3 FeO + CO2 (280-490 C), (3)

    MnCO3 MnO + CO2 (330-500 C) (4)

    According to stoichiometric calculations the results of decomposition are as follows: 1 kg CaCO3

    0.224 m3 CO2, 1 kg MgCO3 0.267 m

    3, 1 kg FeCO3 0.192 m

    3, 1 kg MnCO3 0.194 m

    3.

    Without taking into account the costs of carbonates decomposition, MgCO3 and CaCO3 are the most

    optimal components, which help to get most CO2 when decomposing 1 kg of material, succeeded

    by MnCO3 FeCO3.

    Furthermore, when decomposing CaCO3 and MgCO3 basic oxides CaO and MgO are formed and

    improve basicity of welding flux, and that of a forming slag, respectively, whereas, when MnCO3

    and FeCO3 decomposing oxides FeO and MnO are formed, which raise the degree of oxidation in

    slag systems and oxygen concentration in a weld. The latter causes all negative consequences

    increasing level of impurity by non-metallic oxide components in a weld and deterioration of

    mechanical properties.

    Having followed all mentioned pre-conditions we have developed a flux ANK additive, protected

    it by a patent of the Russian F
