Description
Aus Metallspänen und einem Zement o. dgl. enthaltenden Mantel bestehendes Brikett Bekannt ist das Verfahren, Metallspäne mit hohem oder niederem Druck zu brikettieren und die so entstehenden Formlinge oder Pakete in einer für das Schmelzverfahren geeigneten Weise in den Schmelzofen aufzugeben.Made of metal chips and a coat containing cement or the like Briquette The process of making metal chips with high or low pressure is known Briquetting and the resulting briquettes or packets in one for the melting process to be fed into the furnace in a suitable manner.
Ferner ist auch bekannt, daß man bei der Herstellung dieser Spänebrikette, Pakete usw. Bindemittel als Zusätze verwendet, wie z. B. Kallzmilch usw. Neuere Verfahren schließen auch die mehr oder weniger fest geformten Späne in einen Mantel ein, der aus abbindenden und eüie feste Form gewährleistenden Ausgangsstoffen besteht, .z. B. Beton, Zement oder Mischungen von Zement und Sand.It is also known that in the production of this chip briquette, Packages, etc. binders used as additives, such as. B. Kallzmilch etc. Newer ones Processes also enclose the more or less firmly shaped chips in a jacket a, which consists of setting and a solid form guarantee starting materials, .z. B. concrete, cement or mixtures of cement and sand.
Dieser feste Mantel, mit welchem man die Späneformlinge einhüllt, hat den Zweck, das Spünepaket in geschlossenem Zustande sicher und ohne wesentliche äußere Beschädigung in die Schmelzzone des Ofens zu bringen.This solid coat, with which one envelops the chip moldings, has the purpose of keeping the Spünepaket safe and without essentials when closed bringing external damage into the melting zone of the furnace.
Diese Ummantelung nun zerfällt, nachdem sich ihren Zweck erfüllt hat, und bildet, sofern sie z. B. aus den oben bezeichneten Stollen besteht, in sehr reichlichem und unerwünschtem Ausmaße Schlacken. Diese Schlakken greifen auch das Ofenfutter an und machen öfters Reparaturen notwendig.This sheath is now falling apart after its purpose has been fulfilled, and forms, provided it z. B. consists of the above-mentioned studs, in very copious and undesirable levels of slag. These bad guys grab that too Oven lining and often make repairs necessary.
Diesen bezeichneten Übelständen will die neue Erfindung begegnen und sie entweder ganz ausschalten" oder doch sehr bedeutend herabmindern.The new invention aims to counteract these evils and either turn it off completely "or reduce it very significantly.
Der Weg ist folgender: Die brikettierten oder auch losen Metallspäne werden mit einem Mantel umgeben, genau wie oben als bekannt beschrieben ist. Dieser Mantel besteht aber im Gegensatz nunmehr aus einem Gemisch von brennbaren Stojen, die wenig oder gar keine Schlackenbildner @enthalten und einem Bindemittel, welches z. B. Zement, Kalk, Kalkmilch usw. sein kann. Auch Zuschläge von Silicium, Mangan usw. sind möglich.The way is as follows: The briquetted or loose metal shavings are surrounded with a coat exactly as described above as known. This In contrast, the coat now consists of a mixture of combustible materials, which contain little or no slag formers @ and a binding agent, which z. B. cement, lime, milk of lime, etc. can be. Also additions of silicon, manganese etc. are possible.
