Description

Verfahren zum sulfatisierenden Rösten und Totrösten von Kiesen, Blenden, schwefelhaltigen Erzen und Hüttenerzeugnissen aller. Art. Es ist bekannt, Erze, die im mechanischen Ofen nicht vollständig abgeröstet werden können, dadurch vollkommen ihrer letzten Schwefelanteile zu berauben oder den Schwefel zu Schwefeltrioxyd zu oxydieren, daß sie einem Verblaseprozeß unterworfen werden.Process for sulphatizing roasting and dead roasting of gravels, blends, sulphurous ores and metallurgical products of all. Art. It is known ores, which cannot be completely roasted in the mechanical oven, therefore completely To deprive them of their last sulfur content or to convert the sulfur to sulfur trioxide oxidize that they are subjected to a fading process.

Es hat sich nun herausgestellt, daßbeim Verblasen der im Röstgut enthaltene Staub die vollkommene und rasche Entschwefelung stark hindert.It has now been found that when the toasted material is blown Dust strongly prevents the complete and rapid desulfurization.

Da das heiße, aus dem mechanischen Ofen in den Totröstofen oder Verblaseofen gelangende Material nicht entstaubt werden kann, wurde beobachtet, daß ein äußerst gutes Verblasen des heiß aus dem Ofen kön=enden Materials möglich war, wenn der in dem auf den mechanischen Ofen aufgegebenen Erz enthaltene Staub vor der Aufgabe ausgesondert und in Grieß- oder Kornform verwandelt und -dann dem übriggebliebenen Korn wieder beigemischt wird.Since the hot, from the mechanical oven to the dead roasting oven or blown oven Incoming material cannot be dedusted, it has been observed that an extremely the material, which could be hot out of the furnace, was able to be blown well if the dust contained in the ore loaded on the mechanical furnace prior to loading separated and transformed into semolina or grain form and then the leftover Grain is added again.

Es bildet sich dann nur äußerst wenig Staub beim Durchwandern des Erzes durch den mechanischen Ofen, welche geringe Menge das spätere Verblasen nicht störend beeinfiußt.Very little dust then forms when wandering through the Ore through the mechanical furnace, which small amount the later blowing does not disruptively influenced.

PATENTANSPRUCH: Verfahren zum Totrösten oder sulfatisierenden Rösten von Kiesen, Blenden, schwefelhaltigen Erzen und Hüttenerzeugnissen aller Art durch nachfolgendes Verblasen der im .mechanischen oder sonstigen Feinerzröstofen vorgerösteten Erze, dadurch gekennzeichnet, daß behufs vollkommener Oxydation des Schwefels beim Verblasen des. noch heißen vorgerösteten Erzes aus dem Roherz vor der Aufgabe auf den mechanischen usw. Ofen der feine .Staub abgesondert, in bekannter Weise vergrießt oder in Korn verwandelt dem übrigen Korn wieder beigemischt und die Beschickung so im staubfreien Zustand auf den Ofen gegeben wird. PATENT CLAIM: Process for the dead roasting or sulphatizing roasting of gravels, blends, sulfur-containing ores and metallurgical products of all kinds by subsequent blowing of the ores that have been pre-roasted in a mechanical or other fine-ore roasting furnace, characterized in that the sulfur is completely oxidized when the hot, pre-roasted ore is blown The fine dust is separated from the raw ore before it is placed in the mechanical, etc. furnace, grated in a known manner or transformed into grain, mixed with the rest of the grain, and the charge is placed on the furnace in a dust-free state.
