Abstract

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.

Description

Толкатели имеют форму хордовых сегментов , но они могут быть любой дру гой формы, подход щей дл  данной печи и данной шихты. Кольцевое тело 6 опираетс  на обод печи с помощью кЬнсолей 8 с колесиками 9, которые могут катитьс  по кольцевой дорожзсе 10, при этом возможна люба  друга  известна  установка, котора  позвол  ет кольцу вращатьс  или качатьс  вокруг своей оси.Гидроцилиндр 11 сообщае кольцу 6 качательное движение, дл  этого могут быть также использованы зубчатые передачи или любые другие средства, сообщающие кольцу вращательное или качательное движе | ие . Может быть также использовано несколько концентрических кольцевых тел . В этом случае горизонтальна  Ьи ла от ка)адого кольца, возникающа  от толкатвлей или сегментов, будет передавать своё действие ниже нижнего обода внутреннего кольца. Устройство работает следующим образом . Усилие от гидроцилиндра 10 передаетс  на кольцо 6, которое при 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
