• Characterization of a manganese ore to define its use in

    Fluxes consisting of a system of oxides with high contents of silica and manganese are among those most widely used in welding carbon steels because they possess good technological properties. In Cuba fluxes of this type have mainly been used in the metalmechanical and agricultural sectors. The use of the Ukrainian flux AH348 became common in the 1990s followed more recently by OK Flux-1040
