Description

Elektrisch beheizter Kanalglühafen Es sind .elektrisch beheizte Tunnelöfen mit zwei nebeneinanderlaufenden Deschickungsgleisen bekannt, in die das zu glühende Gut in entgegengesetzter Richtung eingeschoben wird, so daß das geglühte Gut beim Ausfahren seine Wärme an das benachbarte, frisch eingeschobene Glühgut abgeben kann.Electrically heated tunnel kilns These are electrically heated tunnel kilns known with two side-by-side delivery tracks, into which the glowing Good is inserted in the opposite direction, so that the annealed good when Extend its heat to the neighboring, freshly inserted annealing material.

Die Erfindung ermöglicht eine :ähnliche Wärmeausnutzung durch Rückgewinnung der Abkühlwärme bei elektrischen Glühöfen mit im Kreis wandernder Herdsohle. Dies kann dadurch erreicht werden, daß zwei. konzentrische, ringförmige Herdsohlen dicht nebeneinander angeordnet sind und in entgegengesetzter Richtung kreisen. Bei Beschickung und Entnahme durch die gleiche Herdöffnung kann demnach das abkühlende, heraüswandernde Glühgut seine Wärme an das zu glühende, hineinwandernde Glühgut abgeben.The invention enables a similar utilization of heat through recovery the cooling heat in electric annealing furnaces with the hearth base moving in a circle. this can be achieved by having two. concentric, ring-shaped foci soles close together are arranged side by side and circle in opposite directions. When loading and removal through the same hearth opening can therefore be the cooling, moving out Incandescent material give off its heat to the incandescent material that is to be glowed and migrates into it.

In der Zeichnung ist ein Ausführungsbeispiel der vorliegenden Erfindung dargestellt. Sie zeigt einen Glühofen mit zwei ringförmig konzentrisch angeordneten Sohlplatten.In the drawing is an embodiment of the present invention shown. It shows an annealing furnace with two concentrically arranged in a ring Sole plates.

Der Ofen besitzt zwei in entgegengesetzter Richtung umlaufende, konzentrisch angeordnete Herdsohlen a und b. Die Beschickung des Ofens und Entnahme erfolgt von einer Stelle c aus. Die Beheizung des Glühkanals geschieht durch Widerstände g, lt, welche so an den Seiten des Glühkanals verteilt sind, daß eine möglichst große Wärmeausnutzung stattfindet. Wenn die Drehung der Herde in der Richtung der Pfeile erfolgen soll, so müssen die Widerstände, wie die Abbildung zeigt, versetzt zueinander angeordnet sein. Das Glühgut ist durch kleine Kreise angedeutet, deren Strichstärke auf eine mehr oder weniger hohe Temperatur hinweisen soll. Die höchste Temperatur wird ungefähr in "der Mitte der vom inneren und vom äußeren Widerstand beheizten Zone erreicht. Der Ofen besitzt einen äußeren Wärmeschutzmantel e und einen inneren Mantel/. Nach dein Verlassen der Heizwiderstände beginnt sich das Glühgut abzukühlen, wobei die Abkühlwärme durch das entgegenkommende frisch eingetragene Glühgut zum Teil aufgenommen wird. Hierdurch tritt eine Beschleunigung der Abkühlwixkung :ein.The oven has two concentrically arranged hearth soles a and b running in opposite directions. The furnace is charged and removed from a point c. The heating of the glow channel is done by resistors g, lt, which are distributed on the sides of the glow channel so that the greatest possible heat utilization takes place. If the flock is to be rotated in the direction of the arrows, the resistors must be offset from one another, as shown in the figure. The annealing material is indicated by small circles, the line width of which should indicate a more or less high temperature. The highest temperature is reached approximately in the middle of the zone heated by the inner and outer resistance. The furnace has an outer heat protection jacket and an inner jacket /. After leaving the heating resistors, the annealing material begins to cool down Freshly entered annealing material is partially absorbed, which accelerates the cooling process.
