Neuerung an dem unter P. R. 5869 patentirten Verfahren zur Herstellung basischer Ziegel, bestehend in der Anwendung von schwefelsaurem Kalk, welcher frisch dargestellt ist, alsInnovation in the process patented under P. R. 5869 for the production of basic bricks, consisting in the use of sulphate of lime, which is freshly presented as

Bindemittel.Binder.

Patentirt im Deutschen Reiche vom 30. Mai 1879 ab.Patented in the German Empire on May 30, 1879.

Das Verfahren besteht im wesentlichen darin, dafs die mit dem natürlichen Gehalt an Kieselsäure, Thonerde und eventuell Eisenoxyd versehenen oder künstlich damit zu mischenden basischen Materialien, Kalkstein, Dolomit oder dolomitischer Kalkstein, in schärfster Hitze gebrannt und ganz oder zum gröfsten Theil zum Sintern gebracht und danach gepocht und gemahlen werden, nachdem man entweder dieselben langsam hat erkalten lassen oder noch glühend beim Ziehen mit Wasser abgeschreckt hat. Durch letzteres wird das Gesinterte von dem Ungesinterten sofort getrennt und zugleich das Pochen und Mahlen des Gesinterten erleichtert.The process consists essentially in the fact that those with the natural content of silicic acid, Alumina and possibly iron oxide provided or artificially mixed with basic materials, limestone, dolomite or dolomitic limestone, burned in the sharpest heat and wholly or for the most part in part Sintered and then pounded and ground after either the same slowly let it cool down or quenched it with water while it was still glowing Has. The latter immediately separates the sintered from the unsintered and at the same time that Pounding and grinding the sintered material made easier.

Das gepochte und gemahlene Brenngut wird mit Hülfe eines aus frisch dargestelltem schwefelsaurem Kalk bestehenden Bindemittels zu Ziegeln und sonstigen feuerfesten basischen Gegenständen, als Düsen, Stopfen, Stampfmasse, Birnenböden etc., verarbeitet, welche dann ohne weiteres zu allen für die Entphosphorung dienenden Schmelzapparaten Anwendung finden können.The pounded and ground material to be fired is made from freshly prepared sulfuric acid with the aid of a Lime existing binding agent for bricks and other refractory basic objects, processed as nozzles, stoppers, rammed earth, pear bottoms, etc., which then without Further information on all melting apparatus used for dephosphorization can be used can.

Das Bindemittel, welches gestattet, die theils gesinterten, theils geschmolzenen basischen Massen, nachdem dieselben in einer gewöhnlichen Mühle fein gemahlen worden sind, bei einem Zusätze von nur 2 pCt. derartig plastisch zu machen, dafs sie unter Anwendung von Druck (Pressung) und Schlag (vermittelst Klopfer) in jede beliebige Form gebracht werden können, wird dargestellt, indem man gebrannten Kalk mit- wenig Wasser ablöscht und im Augenblicke der gröfsten Erhitzung die Hälfte des Gewichtes an concentrirter Schwefelsäure hinzuschüttet. Es bildet sich alsbald schwefelsaurer Kalk, welcher, sobald das erste heftige Aufbrausen vorüber ist, mit den gebrannten und gemahlenen basischen Materialien vermischt wird und, ganz frisch angewendet, die vorerwähnte Wirkung ausübt.The binder, which allows the partly sintered, partly fused basic Masses after they have been finely ground in an ordinary mill an addition of only 2 pCt. so plastic that they can be made using Pressure (pressing) and impact (by means of knockers) can be brought into any shape, is represented by quenching quick lime with a little water and in an instant half the weight of concentrated sulfuric acid is added to the greatest heating. It sulphate of lime forms immediately, which, as soon as the first violent effervescence is over, is mixed with the fired and ground basic materials and, freshly applied, has the aforementioned effect.

Die Kosten dieses Bindemittels sind sehr gering und die mit Hülfe desselben angefertigten Ziegel und Faconsteine reifsen während des Trocknens nicht, sondern erlangen vielmehr eine zur Verwendung geeignete Härte und schwinden später nicht mehr erheblich.The cost of this binder is very low, as are those made with the aid of it Bricks and faceted stones do not ripen while drying, but rather acquire a hardness suitable for use and no longer dwindle significantly later.
