Description
Verfahren zur Erhöhung der Leistung von Sintergeräten Gegenstand der Erfindung bildet eine weitere Ausbildung des Verfahrens zum Sintern von Eisenerz, Abbränden od. dgl. nach dem Patent 574 777. Der zur Erhöhung der Leistung des Sintergerätes nach dem Hauptpatent vorgesehene Zuschlag an Kalk, vorzugsweise staubförmigem, gebranntem Kalk, wird nach der vorliegenden Erfindung ganz oder teilweise durch Dolomit, insbesondere gehranntem Dolomit, ersetzt, wobei vorzugsweise die benötigte Menge Dolomit dabei nach dem jeweiligen CaO-Gehalt desselben eingestellt wird. Es wurde nämlich gefunden, daß auch durch Zuschlag von. Dolomit eine Leistungssteigerung des Sintergerätes beim Saugzugsintern von insbesondere sauren Eisenerzen erreicht werden kann, wie aus nachstehendem Vergleichsbeispiel zu ersehen ist.Process for increasing the performance of sintering devices is the subject of Invention forms a further embodiment of the method for sintering iron ore, Burning or the like according to patent 574 777. The one to increase the performance of the sintering device According to the main patent, the surcharge of lime, preferably pulverulent, burnt Lime, according to the present invention, is wholly or partly by dolomite, in particular called dolomite, replaced, preferably with the required amount of dolomite is adjusted according to the respective CaO content of the same. It was found that also by adding. Dolomite an increase in the performance of the sintering device can be achieved in the suction sintering of in particular acidic iron ores, such as can be seen from the following comparative example.
Vergleichsbeispiel 35 kg eines sauren Eisenerzes, bestehend aus einer Mischung von q.00/0 Salzgittererz, 15% Pegnitzkonzentrat, 20% südbadische Doggererze, 15% Schwedenschlich und io% Gichtstaub wurden mit 1,75 kg- gebranntem Dolomit von mehlartiger Feinheit, 'mit 7 kg Rückgut und 2, i kg -Koks von - -der Korngröße i bis 3 mm gemischt und in bekannter. Weise gekrümelt. Diese Mischung wurde auf einem Saugzugs-interrost gesintert, wobei sich eine Leistung von 32 t Sinter je qm Saugfläche ergab :gegenüber nur 26 t je qm Leistung beim Fehlen des Dolomitzu.satzes.Comparative Example 35 kg of an acidic iron ore, consisting of a mixture of q.00 / 0 Salzgitter ore, 15% Pegnitz concentrate, 20% South Baden Dogger ores, 15% Swedish and 10% gout dust were mixed with 1.75 kg of burnt dolomite of flour-like fineness 7 k g of return material and 2.1 kg of coke from - -the grain size i to 3 mm mixed and in known. Way crumbled. This mixture was sintered on a suction fan intergrate, resulting in an output of 32 t of sinter per square meter of suction area: compared to only 26 t per square meter of output without the addition of dolomite.
