Nutzbarmachung von MetallschleifspänenUtilization of metal shavings

Es ist bekannt, kleinstückiges Metallmaterial, welches bei einem Dreh- oder Hobelprozeß als Abfall entsteht, wieder dadurch nutsbar zu machen, daß man es erhitzt (wobei es seine Elastizität und Sprödigkeit verliert) und bei Erhitzungs-■meperatur unter Druck- oder Schlaganwendung verdichtet·It is known, small pieces of metal material, which at A turning or planing process arises as waste, to make it nutsable again by heating it (whereby it is its Loses elasticity and brittleness) and when heated ■ temperature compacted under pressure or impact

Die Torliegende Erfindung löst die Aufgabe, sehr feine Metallspäne mit einem Durchmesser von wenigen Zehnteln Millimeter, wie si· beim Sohlelfen mit Schleifscheiben und -steinen anfallen, nutzbar zu machen. Diese Späne werden in kaltem Zustand geprellt, da durch Erhitzen vor dem Pressen die Span· bereits z.T. verbrennen würden; daher let auch der benötigte Verdichtungsdruck höher al· beim Brikettieren nach vorherigem Erwärmen, z.B. ca. 15 kp/mm .The present invention solves the problem of utilizing very fine metal shavings with a diameter of a few tenths of a millimeter, such as those that arise in sole elimination with grinding wheels and stones. These chips are bruised in the cold state, since if they were heated before pressing, the chips would already be partly burned; therefore the required compression pressure is also higher than when briquetting after prior heating, for example approx. 15 kp / mm.

wird. Die Form der Briketts kann z.B. zylindrisch, würfelig oder kugelig sein.will. The shape of the briquettes can be, for example, cylindrical, cubic or be spherical.

Die Schleifspäne können chemisch oder mechanisch gereinigt oder ungereinigt zu Briketts verarbeitet werden·The grinding chips can be cleaned chemically or mechanically or processed into briquettes without cleaning

Zum Einschmelzen der Briketts empfiehlt es sich, si-e in ein überhitztes Metallbad kontinuierlich oder chargenweise einzusetzen. Besonders geeignet ist hierfür ein Induktionsofen mit möglichst hohem Pincheffekt, d.h. niedriger Frequenz, damit die Briketts im Metallbad bewegt werden· Der Induktionsofen ist ein Tiegelofen zum Schmelzen von Metallen, der durch außen liegende von Wechselstrom durchflossene Spulen mit Energie versorgt wird, wobei in der Metallcharge ein Strom induziert wird, dessen unterschiedliche Dichteverteilung zusammen mit dem gleichfalls entstehenden Magnetfeld eine ständige Bewegung und Durchmischung des geschmolzenen Metalls bewirkt·To melt the briquettes it is advisable to use them continuously or in batches in an overheated metal bath. An induction furnace with the highest possible pinching effect, i.e. low frequency, is particularly suitable for this Briquettes are moved in a metal bath · The induction furnace is a crucible furnace for melting metals by means of external Coils through which alternating current flows is supplied with energy, with a current being induced in the metal charge, its different Density distribution together with the likewise arising magnetic field a constant movement and mixing of the molten metal causes

Bei nicht induktiv beheizten Öfen empfiehlt es sich*, die Briketts durch Gewichtsbelastung zu tauchen, um den Abbrand möglichst niedrig zu kalten·In the case of non-inductively heated ovens, it is recommended * to immerse the briquettes by placing them under weight in order to keep the burn as low as possible

Beim Einsatz im Induktionsofen spielt die Größe der Briketts eine wesentliche Rolle· Die maximale Größe der Briketts hängt von der Badbewegung ab, die diese Briketts Bit unter die Badoberflache sieheii muS.When used in induction ovens, the size of the briquettes plays a role essential role · The maximum size of the briquettes depends on the bath movement that these briquettes bit under the bath surface see ii must.
