Abstract

This is an addn. to 2437036, describing metal recovery processes, esp. those working with sintering- and condensn. - plants, particularly condensn. plants. In the present invention, the novelty is that the condenser is provided with a sepg. layer to prevent the pronounced adhesion of deposits of metal and dust, the layer being based on a refractory. Alternatively, the sepg. layer is pref. based on (a) an alkaline earth combination; (b) a hydrocarbon; (c) a metal; (d) carbon or graphite; (e) silicon; (f) a plastic; (g) or on a combination of any of the materials mentioned. Eliminates the need to use hammers and chisels to remove adherent deposits which have baked onto the walls e.g. of sintering plants, such as the wind boxes, the condenser, the condenser tower or the cross-over.

Description

Horbacher Str. 313 vom 20. Jan. 1975, Metallgewinnungsverfahren Beschreibung Es gibt Metallgewinnungsverfahren, die über Sinteranlagen und Kondensationsanlagen zum gewünschten Metall führen.Horbacher Str. 313 of Jan. 20, 1975, metal recovery process description There are metal extraction processes that involve sintering plants and condensation plants lead to the desired metal.

Bei die sei Verfahren treten erhöhte Schwierigkeiten durch Metallablagerungen und Staubablagerungen auf, die durch Meißeln und Hämmern entfernt werden müssen. Das führt neben einem enorm hohen Arbeitsaufwand zur Beschädigung der Anlageaggregate. So sind z. B. die Windkästen der Sinteranlagen weiterhin der Condensor und der Condensorturm mit anschließendem Crossover ganz besonders gefährdete Teile.In the case of the process, there are increased difficulties due to metal deposits and dust deposits that must be removed by chiselling and hammering. In addition to an enormous amount of work, this leads to damage to the system units. So are z. B. the wind boxes of the sintering plants continue to be the condenser and the condenser tower with a subsequent crossover particularly endangered parts.

Um diese Nachteile zu beseitigen, entwickelte der Erfinder Produkte auf verschiedenen Basen, die als Trennschicht aufgetragen, ein Anbacken der Netallablagerungen verhindern und ihre leichte Entfernung ermöglichen.In order to overcome these disadvantages, the inventor developed products on different bases, which are applied as a separating layer, a caking of the metal deposits prevent and allow their easy removal.

Durch Versuche wurden mehrere geeignete Trennfilme entwickelt. Der Erfinder fand, daß bestimmte Kohlen-Wasserstoffverbindungen sich eignen, weiterhin Erdalkalikombinationen.Several suitable release films have been developed through experimentation. Of the The inventor also found that certain carbon-hydrogen compounds are useful Alkaline earth combinations.

Auch feuerfeste sowie metallische Produkte hatten bei geeigneten Bindemitteln den gewünschten Erfolg.Refractory and metallic products also had suitable binders the desired success.

Schließlich war die Realisierung einer solchen Trennschicht auch durch Kohlenstoff-Bindemittelkombinationen möglich.Finally, the realization of such a separating layer was through Carbon-binder combinations possible.

Mischungen der angegebenen Produkte waren ebenfalls ausgezeichnet.Mixtures of the listed products were also excellent.

S@ ist es möglich die Wirtschaftlichkeit des Verfahrens wesentlich zu erhöhen.S @ it is possible the economics of the process are essential to increase.
