METHOD OF TRANSPORTING LIQUID METAL FROM METALLURGICAL FURNACE TO POURING VESSELS AND APPARATUS FOR PERFORMING THE METHOD Russian patent published in 1995 - IPC

FIELD: metallurgy. SUBSTANCE: in system, having at least transporting and draining chutes, mounted near one output hole of a metallurgical furnace, and transfer station with a rotary or rocking chute, in which the melt metal flows from the draining chute through a distribution system into output holes to be fed mainly into pouring vessels, being moved, it is proposed to close the draining chutes by closing casings, guiding the melt metal from the output holes of the furnace, to significantly shield by gas-tight fashion the transfer station, to wash out respective inner cavities by an inert gas and to shield in addition from air penetration at draining a stream of the melt metal, flowing from the output hole until an input to the pouring vessel, with use of an envelope of the inert pressurized gas; the casing, having a cross section, mainly a form of a ring. EFFECT: enhanced structure of the apparatus, providing simplification of the method. 31 cl, 7 dwg
