Description

Verfahren zur Herstellung von Eisenschwamm Die Erfindung bezieht sich auf Verfahren zur Herstellung von Eisenschwamm nach Patent 5a9 136. Process for the production of sponge iron The invention relates to the process for the production of sponge iron according to patent 5a9136 .

Es ist bereits vorgeschlagen worden, die aus zur Herstellung von Eisenschwamm dienenden Reduktionsschächten für Eisenerze entweichenden Abgase in Regeneratoren, die aus einem mit glühendem Koks gefüllten Schacht bestehen, zu regenerieren, das heißt das Gas durch Umsetzung mit Kohlenstoff von der Kohlensäure zu befreien.It has already been proposed to be used for making sponge iron serving reduction shafts for iron ore escaping exhaust gases in regenerators, which consist of a shaft filled with glowing coke to regenerate the means to free the gas from the carbonic acid by reacting it with carbon.

Der Erfindung gemäß kann man einen Eisenhochofen selbst als einen solchen Karburator benutzen, indem man das Gichtgas, das karburiert und erhitzt werden soll, unterhalb der Stelle, an der es für die Zwecke der Verwendung als Reduktionsgas in einem Erzreduktionsschacht entnommen wird, in den Schacht des Hochofens einführt, so daß ein ständiger Gasnebenstrom durch den Ofen geht, ohne daß das Gleichgewicht des Hauptvorganges im Hochofen gestört wird.According to the invention, one can use an iron blast furnace itself as one use such a carburator by adding the furnace gas that is carburized and heated should be below the point where it is for the purpose of use as a reducing gas is removed in an ore reduction shaft, introduced into the shaft of the blast furnace, so that a constant bypass flow of gas goes through the furnace without affecting the equilibrium the main process in the blast furnace is disturbed.
