Description
Elektrisk induksjonsovn. Electric induction oven.
For å smelte eller holde aluminium, sink eller legeringer derav i smeltet tilstand samt for å behandle gjenstander i en smelte av disse stoffer anvendes bl. a. lavfrekvens-induksjonsovner av renne-type, dvs. ovner hvor det under smeltekaret er anordnet en eller flere U-formede renner eller kanaler, som er fylt med bly som utgjør ovnens sekundærkrets og som tjener som varmeformidler til det smeltete metall som ligger over bly-speilet. Der-ved utnyttes de forskjellige metallers forskjellige spesifikke vekter og det kjente faktum at aluminium og sink ikke legerer seg særlig med bly. To melt or keep aluminum, zinc or alloys thereof in a molten state, as well as to treat objects in a melt of these substances, e.g. a. trough-type low-frequency induction furnaces, i.e. furnaces where one or more U-shaped troughs or channels are arranged under the melting vessel, which are filled with lead which forms the secondary circuit of the furnace and which serves as a heat transfer agent to the molten metal lying above the lead mirror. Thereby, the different specific weights of the different metals and the well-known fact that aluminum and zinc do not alloy particularly well with lead are used.
Ved slike ovner som i regelen har smelterenner utført av jern, har det vært vanskelig å få en fullgod tetting mellom den ikke keramiske smelte-renne og den keramiske digel. In the case of such furnaces, which as a rule have melting troughs made of iron, it has been difficult to get a perfect seal between the non-ceramic melting trough and the ceramic crucible.
Foreliggende oppfinnelse går ut på en slik anordning, at smelterennen, selv om den på grunn av varmepåvirkning utvider eller kaster seg, ikke på noen måte kan påvirke den keramiske foring for smeltekaret da den øvre ende av smelterennen ligger helt fri fra foringen. Den nye anordning forhindrer samtidig at aluminium, sink eller legeringene derav kommer i be-røring med jernet i smelterennen. Jern angripes som bekjent lett av aluminium og sink. The present invention is based on such a device that the melting chute, even if it expands or collapses due to the influence of heat, cannot in any way affect the ceramic lining for the melting vessel as the upper end of the melting chute is completely free from the lining. The new device also prevents aluminium, zinc or their alloys from coming into contact with the iron in the smelter. As is well known, iron is easily attacked by aluminum and zinc.
Det nye ved ovner av den art som er beskrevet ovenfor er, at den øvre ende av smelterennenes jernvegg er forsynt med en oppstående krave som sammen med en flens som raker nedover fra smeltekaret danner en væskelås for aluminium, sink eller deres legeringer. What is new about furnaces of the type described above is that the upper end of the iron wall of the melting chute is provided with a raised collar which, together with a flange that extends downwards from the melting vessel, forms a liquid lock for aluminium, zinc or their alloys.
For nærmere å forklare oppfinnelsen skal det henvises til vedføyede tegning, som i fig. 1 og 2 viser to alternativer. Fig. 2 viser dessuten ytterligere en forbedring ved den nye ovnstype. To explain the invention in more detail, reference should be made to the attached drawing, which in fig. 1 and 2 show two options. Fig. 2 also shows a further improvement in the new oven type.
Ovnskaret som opptar det stoff som skal smeltes, holdes i smeltet tilstand eller anvendes for overflatebehandling av gjenstander dannes av en keramisk foring 1. The furnace vessel that holds the substance to be melted, kept in a molten state or used for the surface treatment of objects is formed by a ceramic lining 1.
Fra bunnen av ovnskaret strekker det seg It extends from the bottom of the oven tray
en smelterenne 2, som opptar blyet 3. Det står i smeltet tilstand så høyt at det også dekker bunnen av smeltekaret. På blyet ligger det smeltete metall 4 (aluminium, sink eller legeringer derav). En primær-spole 5 på en jernkjerne 6 induserer lav-frekvente strømmer i blyet som tjener som sekundærkrets. a melting chute 2, which receives the lead 3. It stands in a molten state so high that it also covers the bottom of the melting vessel. On the lead lies the molten metal 4 (aluminium, zinc or alloys thereof). A primary coil 5 on an iron core 6 induces low-frequency currents in the lead which serves as the secondary circuit.
I henhold til oppfinnelsen er veggen i smelterennen forsynt med en forlengelse 7, som strekker seg oppover. Foringen 1 er forsynt med en flens 8, som er rettet nedover slik at det dannes en væskelås for det smeltete metall 4. Væsken i låsen ut-gjøres av det smeltete bly. Som vist ligger rennen helt fri i foringen. According to the invention, the wall in the melting chute is provided with an extension 7, which extends upwards. The liner 1 is provided with a flange 8, which is directed downwards so that a liquid lock is formed for the molten metal 4. The liquid in the lock consists of the molten lead. As shown, the channel is completely free in the liner.
Som sikkerhetsforanstaltning har væskelåsen et overløp 9 for blyet hvis det stiger over den øvre rand av væskelåsen. As a safety measure, the liquid lock has an overflow 9 for the lead if it rises above the upper edge of the liquid lock.
Den ovn som er vist i fig. 1 kan ikke tippes for tapping, noe som forøvrig ikke er nødvendig når ovnen skal anvendes for overflatebehandling av gjenstander (alu-minisering, forsinking). Hvis ovnen er be-regnet for smelting, foregår tapping ved at et fortrengningslegeme 10, som fortrinsvis er hult og består av keramisk material senkes ned i smeltebadet. Det smel-tede metall flyter da ut over tappeløpet 11. The oven shown in fig. 1 cannot be tipped for tapping, which is incidentally not necessary when the oven is to be used for surface treatment of objects (aluminisation, zinc plating). If the furnace is designed for melting, tapping takes place by lowering a displacement body 10, which is preferably hollow and consists of ceramic material, into the melting bath. The molten metal then flows out over the spout 11.
I en slik ovn kan den nedadrettede flens 8 In such a furnace, the downward-facing flange 8
på foringen 1, fig. 1, dannes av en normal on the lining 1, fig. 1, is formed by a normal
grafitdigel 12 hvor bunnen er skåret bort. graphite crucible 12 where the bottom has been cut away.
