DEVICE FOR SUPPLY AND PRE-HEATING OF METAL CHARGE OF MELTING UNIT

摘要

FIELD: metallurgy.SUBSTANCE: invention relates to metallurgy, and can be used for continuous feeding with pre-heating of the metal charge to the melting unit receiver. Device contains at least channel for the metal charge feeding, at least cap installed above the specified feed channel creation tunnel and/or expansion chamber for movement inside it of at least part of the flue gases exiting the specified receiver, and holes made together with side walls of the specified feed channel for the flue gases discharge. The feed channel contains activators to deviate the flue gases and/or to separate areas of the feed channel occupied by the metal charge, at that specified activators are connected longitudinally with at least part of the feed channel.EFFECT: invention ensures more intensive and uniform heating of the metal charge to increase the unit capacity upon energy decreasing required for further melting in the melting furnace.9 cl, 10 dwg
