FIELD: metallurgy; equipment of furnaces. SUBSTANCE: transportation device 4 for metered delivery of loose material from one metallurgical container into the other has transportation channel 6, inlet hole 17, outlet hole 12. Installed in transportation channel 6 is transportation screw 11 extending from inlet hole 17 to outlet hole 12, as a minimum. Transportation screw 11 has screw surface 16 formed by blades 19. To make screw as short as possible and to provide higher resistance to gas flow, transportation screw 11 has section of screw surface 16 on its end corresponding to outlet hole 12 of transportation channel 6. This section is formed by continuous screw line 18 extending through at least half the turn to which screw surface 16 formed by blades 19 adjoins. EFFECT: enlarged operating capabilities. 7 cl, 4 dwg
