    1480805 Stirring furnace charges ELKEMSPIGERVERKET AS 22 Oct 1974 [23 Oct 1973] 45646/74 Heading F4B An electrical melting furnace comprises a furnace crucible 1 enclosing a hollow coaxial member 6 mounted for oscillation or rotation about the common axis and having pushers 7 for inducing inward radial movement of the charge. As shown the pushers 7 are segments on the bottom of member 6 which is supported by struts 8 on wheels 9 rolling on a track 10 by action of hydraulic motors (not shown). The pushers may also be adjustably mounted tangentially of the member 6 and several of the latter may be employed with the pushers at stepped heights.

    Pushers have the form of chord segments, but they can be of any other form suitable for a given furnace and a given charge. The annular body 6 is supported on the rim of the furnace with the help of konsols 8 with wheels 9, which can roll along the annular rails 10, and any installation is possible that allows the ring to rotate or swing around its axis. Hydraulic cylinder 11 communicates ring 6 with oscillating motion, To do this, gears or any other means can be used to communicate the rotational or swinging motion of the ring | not Several concentric ring bodies can also be used. In this case, the horizontal section of the ring, arising from the pusher or segments, will transmit its action below the lower rim of the inner ring. The device works as follows. The force from the hydraulic cylinder 10 is transmitted to the ring 6, which when

    rotational or oscillatory motion transmits it to the pushers 7, which provide horizontal rerouting into account during examination 30. Ryss, I.A. Rotary ore-smelting furnaces. M., 1966, p. 28. Placing the mixture from the walls to the center of the furnace. The advantages of using the proposed device are to eliminate the uneven fractional composition of the charge in the horizontal plane of the furnace, to destroy the formed charge specimens, to increase its gas permeability, as well as to ensure a more uniform charge in the furnace volume, Formula of the Invention The device for moving and distributing powder in the electric furnace containing An agitator placed in a furnace crucible, characterized in that, in order to increase the degree of uniform distribution of the charge in the crucible, chi, the agitator is in the form of one or more rings, arranged concentrically with the crucible, and is provided with pushers mounted in the lower portion of the rings on their inner side. and having the form of running segments, sources of information.
