Abstract
The results of investigation into reactivity of fine ferroalloys (ferrosilicium FS-45, ferromanganese, ferrosilicomanganese, etc.) used in production of electrodes as weld metal deoxidizers and alloying elements of the weld metal, are presented. Individual batches of ferrosilicium FS-45 were revealed to have an extremely high reactivity. It was suggested that such high reactivity might be associated with peculiarities of the production technology, which could either deteriorate homogeneity of ferrosilicium ingots or cause formation of particularly reactive structural components.
Keywords: production of electrodes, electrode compound, liquid glass, ferroalloys, reactivity, gas emission, passivation
