Description

Verfahren zur Nutzbarmachung von metall-, blei-, zink-, zinn- und kupferhaltigem oder emailliertem Eisenschrott. Der Eisenschrott ist infolge seines Gehaltes an Fremdmetallen, Kupfer Zink, Zinn usw., zur direkten Verhüttung auf Eisen, sei es im Martinofen oder im Eisenhochofen in den meisten Fällen ungeeignet, weil das auf diese Weise erzielte Roheisen bzw. der erzielte Stahl diese Metalle aufnimmt und dadurch eine schlechte @Qualität bekommt. Auch Eisenschrott, der mit Emaille überzogen ist, läßt sich infolge des hohen Gehaltes der Emaille an Flußmitteln nur mit großen Schwierigkeiten im Martin- oder Eisenhochofen verarbeiten, da das Ofenmauerwerk bei den in diesen Öfen herrschenden hohen Temperaturen sehr stark angegriffen wird.Process for harnessing metal, lead, zinc, tin and copper-containing or enamelled scrap iron. The scrap iron is due to his Content of foreign metals, copper, zinc, tin, etc., for direct smelting on iron, be it in the Martin furnace or in the iron blast furnace in most cases unsuitable because the pig iron obtained in this way or the steel obtained absorbs these metals and thus gets a bad @ quality. Also scrap iron, the one with enamel is coated, can only be used due to the high content of flux in the enamel process with great difficulty in the Martin or iron blast furnace, because the furnace masonry is very strongly attacked at the high temperatures prevailing in these ovens.

Die vorliegende Erfindung ist bestimmt, diese Nachteile zu beseitigen, und zwar dadurch, daß man Aden Eisenschrott einer Schmelzung im Bleihochofen evtl. unter Zugabe von bleiischen Stoffen unterwirft. Eisen und Zink gehen dabei unter Oxydation zu Eisenoxydul bzw. Zinkoxyrd ebenso wie die Emaille in die entstehende Schlacke, während Zinn zum größten Teil in das Blei und Kupfer in Aden erzeugten Stein übergehen. Die erzeugte eisen- und zinkhaltige Schlacke läßt sich in bekannter Weise im Eisenhochofen verarbeiten. Die übrigen Metalle des Schrottes werden aus dem erzeugten Blei bzw. Stein wiedergewonnen.The present invention is intended to overcome these drawbacks, namely by removing Aden scrap iron from a smelting in the lead furnace, possibly subject to the addition of lead substances. Iron and zinc are lost in the process Oxidation to iron oxide or zinc oxide as well as the enamel in the resulting Slag, while tin for the most part in the lead and copper produced in Aden Pass stone. The produced iron and zinc-containing slag can be known in Process in the iron blast furnace. The remaining metals in the scrap are made from recovered from the lead or stone produced.

PATENTANSPRUCH: Verfahren zur Nutzbarmachung von metald-, blei-, zink-, zinn- und kupferhaltigem oder emailliertem Eisenschrott, dadurch gekennzeichnet, daß der Schrott im Bleiofen evtl. unter Zugabe von bleiischen Materialien zu einem Erzeugnis verschmolzen wird, das sich auf Grund seines Eisen-und Zinkgehaltes zur Verhüttung im Eisenhochofen .eignet, während die anderen im Schrott enthaltenen Metalle aus den übrigen Erzeugnissen der Schmelzung gewonnen werden. PATENT CLAIM: Process for the utilization of metal, lead, zinc, tin and copper or enameled iron scrap, characterized in that the scrap is fused in the lead furnace, possibly with the addition of lead materials, to form a product which is based on its iron and zinc content for smelting in the iron blast furnace. Suitable, while the other metals contained in the scrap are obtained from the other products of smelting.
