Description

Verfahren zum Brikettieren von Feinerzen, Gichtstaub, Kiesabbränden und sonstigen verhüttbaren Stoffen Die Brikettierung von Feinerzen ist heute eine wichtige Frage geworden. Die bei der Brikettierung nötige Formgebung erfolgte bisher ausschließlich auf Fallpressen, Kniehebel-oder Drehtischpressen mittels Preßstempeln in allseitig geschlossenen Formen. Gerade die Formgebung und die damit verbundenen Maßnahmen erforderten aber bei-der Herstellung der Erzbrikette bisher sehr viel Zeit und Unkosten. Obgleich die Verfahren zum Einbinden von Feinerzen in letzter Zeit wesentlich verbessert wurden, sind die Methoden der Formgebung noch verbesserungsbedürftig.Process for briquetting fine ores, blast furnace dust, gravel burn-off and other smeltable materials Briquetting of fine ores is one of them today become an important question. The shaping required for briquetting has so far taken place exclusively on drop presses, toggle presses or rotary table presses using press rams in forms closed on all sides. Especially the design and the related Up to now, however, measures have required a great deal in the manufacture of the ore briquette Time and expense. Although the process for incorporating fine ores in the last The methods of shaping are still in need of improvement.

Es wurde nun gefunden, daß die bisher für Braunkohle üblichen Strangpressen sich überraschenderweise auch mit Vorteil in vielen Fällen für die Brikettierung von Feinerzen, Gichtstaub und sonstigen verhüttbaren Stoffen verwenden lassen. Dies war keineswegs vorauszusehen, da bisher angenommen wurde, daß eine Verpressung dieser Materialien auf der Strangpresse nicht möglich sei. Durch die gefundene Möglichkeit der Brikettierung von Feinerzen mittels der Strangpresse ist ein bedeutender Fortschritt insofern erreicht, als ein allseitig und mit hohem Druck gedrücktes und sehr festes Brikett in einem Format erhalten wird, welches für den Hochofen besonders günstig ist. Durch die hohe Leistung der Strangpresse wird die Brikettierung wesentlich billiger und vorteilhafter als mit den bisher üblichen Pressen.It has now been found that the extrusion presses that have hitherto been customary for lignite Surprisingly, it is also advantageous in many cases for briquetting of fine ores, gout dust and other smeltable materials can be used. this was by no means foreseeable, since it was previously assumed that this would be pressed Materials on the extruder is not possible. Through the opportunity found the briquetting of fine ores by means of the extruder is a significant advance achieved in that it is very solid and pressed on all sides and with high pressure Briquette is obtained in a format which is particularly favorable for the blast furnace is. The high output of the extruder makes briquetting essential cheaper and more advantageous than with the previously common presses.
