Description

Verfahren zur Herstellung von Kokillenbodensteinen Die Erfindung bezieht sich auf einen Kokillenb.odenstein zur Herstellung von Stahlblöcken. Die bisher gebräuchlichen Steine hierfür bestehen aus feuerfestem Werkstoff, der jedoch durch das Aufschlagen des Stahlschmelzstrahles sehr leicht zum Abblättern und Ausbrechen neigt. Damit entstehen aber leicht Einschlüsse aus feuerfesten Bestandteilen des Kokillenbodensteines im Stahlblock. Dadurch entsteht die weitere Gefahr, daß aus dem Sta:hlbliock hergestellte Gegenstände Ausse'huß werden. Dias ist um so nachteiliger, als der Stahlblock sehr häufig eine sehr weitgehende und kostspielige Bearbeitung erfahren hat, ehe dieser Fehler festgestellt wird.Process for the production of mold base bricks The invention relates to on a chill block for the production of steel blocks. The so far Common stones for this consist of refractory material, which, however, through the impact of the molten steel jet very easily to flake and break away tends. However, this easily creates inclusions from refractory components of the Mold bottom stone in the steel block. This creates the further risk that from Objects manufactured in the steel are excluded. Dias is all the more disadvantageous than the steel block very often a very extensive and expensive machining experienced before this error is detected.

Es gelingt in überraschend einfacher Weise, diese Nachteile zu beheben, und zwar dadurch, daß als Kokillenbiodenstein die an sich bekannten sog. Köhlenstoffsteine verwendet -erden. Bekanntlich finden Kohlenstoffsteine sonst nur für das Gestell und die Rast der Hochöfen und für andere metallurgische Schmelzöfen Verwendung. Der Koki:llenbodenstein kann auch in der Weise ,angefertigt werden, wie es für die Herstellung von Elektroden für Lichtbogenöfen zum Schmelzen von Stahl üblich ist. An Stelle von bohle kann auch Graphit verwendet werden.It is possible to remedy these disadvantages in a surprisingly simple manner, in that the so-called carbon stone, known per se, is used as a permanent mold biodestone used -ground. As is well known, carbon stones are usually only found for the frame and the rest of the blast furnaces and use for other metallurgical smelting furnaces. The Koki: llenbodenstein can also be made in the way, as it is for the Manufacture of electrodes for electric arc furnaces for melting steel is common. Graphite can also be used instead of bohle.

Bekanntlich werden Kohlenstoffsteine aus fein gemahlenem Koks oder Holzkohle mit Teer als Bindemittel 'hergestellt. Infolge ihrer leichten Verbrennliclhkeit werden die Steine in geschlossenen Räumen mit gemahlenem Koks abgedeckt oder in Koks eingebettet gebrannt. In ähnlicher Weise werden Elektroden in Lichtbogenöfen zuni Schmelzen von, Stahl hergestellt. Nur geht man hier häufig von fein gemahlenem, möglichst aschefr.-iem Pechkoks aus.It is known that carbon bricks are made from finely ground coke or Charcoal made with tar as a binder '. Due to their easy burnability the stones are covered with ground coke in closed rooms or in Burnt coke embedded. Similarly, electrodes Manufactured in electric arc furnaces to melt steel. It's just that you go here often made from finely ground pitch coke that is as ash-free as possible.

Ausgedehnte Versuche ergaben, daß @ etfindungsgemäß verwendete Iiokilljenbodenstein@ während des Atiftreffens des Stahlschrnelzstrahles weder abblättern noch nusbrechii. Hierdurch wird erreicht, daß fertig gegossen,: Stahlblöcke keine feuerfesten Einschlüsse mehr aufweisen, 'da der Stein eine große Haltbarkeit besitzt.Extensive tests have shown that Iiokilljenbodenstein @ used according to the invention neither flake off nor nusbruchii during the impact of the steel melt jet. This ensures that the cast is finished: Steel blocks have no refractory inclusions have more, 'because the stone has a great durability.
