APPLICATION OF NITROGEN DUST REMOVAL PLANTS AT PIG IRON CASTING IN FERROUS METALLURGY
The experience of operation of nitrogen dust removal plants at pig iron casting in mixer departments and in casting departments of steelmaking shops and at blastfurnace shops have been generalized. Long lasting operational practice has proved that dust removal plants are simple and reliable, they do not demand considerable costs, provide high efficiency of red fume removal and do not effect on technological indices. Proved longterm use, that dust suppression installations simple and reliable, do not require significant investment, provide high efficiency of suppression of red fume and do not affect the technological parameters.
