backt nnd ihre Porosität verliert oder gar eine Sinterung eintritt. Vielmehr ist es vorteilhaft, noch einen ganz geringen Grad von Feuchtigkeit in der Masse zu belassen, da hiedurch das Eindringen des Kalziumchlorids befördert wird. Nach erfolgter Umsetzung wird dann die Feuchtigkeit wiederum ausgetrocknet und man erhalt auf diese Weise ein vollkommen hartes, widerstandsfähiges, dauerhaftes Futter, welches auch der Einwirkung der bei den späteren metallurgischen Operationen benutzten, ausserordentlich hohen Temperaturen widersteht und keine weitere Veränderung erleidet.
Die dem basischen Material zuzufügende Menge Wasserglas beträgt zweckmässigerweise so viel, dass die entstehende Mischung 2-30/0 Kieselsäure enthält ; doch ist es selbstverständlich, dass man an diesen Prozentsatz nicht gebunden ist, sondern denselben den Umstanden entsprechend abändern kann.
Man kann auch in der Weise verfahren, dass man die bei der Herstellung des Futters benutzten Materialien zunächst mit Kalziumchlorid mischt und alsdann erst das Wasserglas zufügt. Doch empfiehlt sich das umgekehrte Verfahren wegen der ausserordentlichen Ilygroskopizität des getrockneten Kalziumehlorida.
PATENT-ANSPROCHE-
1. Verfahren zur Herstellung eines basischen Ofenfutters für metallurgische Zwecke unter Verwendung einer Mischung von Kalziumchlorid und Wasserglas, dadurch gekennzeichnet, dass derselben basische, bei der Hydratisierung keine wesentliche Volumverandemng erleidende, schwer schmelzbare Materialien, wie Magnesiumoxyd bezw. magnesia, Chromoxyd, Chromeiseustein u. dgl. zugefügt werden.

bakes and loses its porosity or even sintering occurs. Rather, it is advantageous to leave a very low level of moisture in the mass, as this promotes the penetration of calcium chloride. After the conversion has taken place, the moisture is then dried out again and in this way a completely hard, resistant, permanent lining is obtained, which also withstands the effects of the extremely high temperatures used in the later metallurgical operations and does not suffer any further changes.
The amount of waterglass to be added to the basic material is expediently so much that the resulting mixture contains 2-30 / 0 silica; but it goes without saying that you are not bound to this percentage, but can change it according to the circumstances.
One can also proceed in such a way that the materials used in the production of the feed are first mixed with calcium chloride and only then the water glass is added. However, the reverse procedure is recommended because of the extraordinary lygroscopicity of the dried calcium chloride.
PATENT APPROACH
1. A process for the production of a basic furnace lining for metallurgical purposes using a mixture of calcium chloride and water glass, characterized in that the same basic, difficult to melt materials, such as magnesium oxide or magnesium oxide, which suffer no significant volume change during hydration. magnesia, chromium oxide, chromium oxide stone u. Like. Be added.
