KAISERLICHESIMPERIAL
PATENTAMTPATENT OFFICE
Der Gegenstand vorliegender Erfindung bezieht sich auf das im Patent 159584 gekennzeichnete Verfahren zur Herstellung von blasenfreiem Stahl, nach welchem das Innere der Gießpfanne oder Blockform mit einer Wärme erhaltenden Schicht überzogen oder ausgekleidet wird, welche vorteilhaft aus kohlenstoffhaltigen Stoffen mit Kalk als Bindemittel besteht und den Zweck hat, den Glasiiberzug möglichst lange flüssig und wirksam zu halten.The subject matter of the present invention relates to that identified in patent 159584 Process for the production of bubble-free steel, according to which the interior the ladle or block mold coated with a heat-retaining layer or is lined, which is advantageous from carbonaceous substances with lime as The purpose of the binder is to keep the glass coating liquid and effective for as long as possible to keep.
Bisher wurden eiserne Formen verwendet, welche mit der kohlenstoffhaltigen Masse ausgekleidet wurden.So far, iron forms have been used, which are lined with the carbonaceous mass became.
Die Erfinder haben nun gefunden, daß es für die Praxis sehr vorteilhaft ist, die Blockformen durchweg aus Kohlenstoff herzustellen, in welche dann das glasige oder glasartige Gemenge als Schutz eingebracht wird.The inventors have now found that it is very advantageous in practice to use the block molds consistently made of carbon, in which then the glassy or vitreous mixture is introduced as protection.
Zur Herstellung der neuen Blockformen wird Koks mit Graphit und Kohle oder Teer oder einer anderen Masse als Bindemittel gemischt, in einer Presse zur erforderlichen Form gepreßt und hiernach in einem Ofen hart gebrannt.Coke with graphite and coal or tar is used to manufacture the new block molds or another mass mixed as a binder, in a press as required Pressed in the form and then fired hard in an oven.
Die kohlenstoffhaltigen Formen können vorteilhaft zum Transport und Schutz gegen Zerbrechen von einem eisernen oder hölzernen Kasten umgeben werden, welcher diagonal geöffnet werden kann, um ein schnelles Auswechseln zu ermöglichen. Auf diese Weise kann eine große Anzahl Blockformen vorrätig gehalten werden, wodurch keine Betriebsstörung entstehen kann. -The carbonaceous forms can be beneficial for transportation and protection against Breaking be surrounded by an iron or wooden box, which opens diagonally can be used to enable quick replacement. In this way, a large number of block shapes can be kept in stock are held, so that no malfunction can occur. -
Durch die Herstellung der Blockformen durchweg aus Kohlenstoff fallen die bisher in Gebrauch befindlichen teuren, gußeisernen Blockformen weg, wodurch die Herstellungskosten von Stahl ganz bedeutend verringert werden, da die Masse der kohlenstoffhaltigen Blockform wieder verwendet werden kann und der sie umschließende Kasten durch den heißen Stahl nicht berührt wird und somit auch dauerhafter ist. Die kohlenstoffhaltigen Blockformen können auch die bisher gebräuchlichen Ausgleich- und Durchweichungsgruben ersetzen.Due to the fact that the block molds are made entirely of carbon, they are no longer available expensive cast iron block molds in use, reducing manufacturing costs of steel can be significantly reduced, since the mass of the carbon-containing Block shape can be used again and the box enclosing it through the hot steel is not touched and is therefore more durable. The carbonaceous ones Block molds can also use the previously common compensation and soaking pits substitute.
