Formstein für l'richteraufsätze und -auskleidungen insbesondere bei Stahl- und GraugußhersteilungMolded stone for judge attachments and linings especially for steel and gray cast iron production
Die Erfindung bezieht sich auf einen für 'Trichteraufsätze oder -auskleidungen insbesondere bei Stahl- und Graugußherstellung bestimmten formstein und bezweckt, den Stein so auszubilden, daß ein möglichst langzeitiger Wärmeschutz erreicht und ein vorzeitiges Erkalten der Gußmasse verhindert wird.The invention relates to one for 'funnel attachments or linings, especially in steel and gray cast iron production, certain shaped stone and aims to make the stone so train that achieves long-term thermal protection and prevents premature cooling of the casting compound will.
.Dieses Ziel ist erfindungsgemäß dadurch erreicht, daß die aus feuerfestem Material bestehenden Formsteine mit zur Aufnahme von Isolierstoffen dienenden Hohlräumen versehen sind. Zweckmäßig bestehen dabei die Steine je aus einem länglich flachen Quader, der vorteilhaft parallel zu seiner Breite mit einer Mehrzahl von kanalartigen und pulverförmige Isolierstoffe aufweisenden Hohlräumen versehen sind..This goal is achieved according to the invention in that the refractory material existing bricks with for inclusion are provided by insulating materials serving cavities. Appropriate consist of the stones each from an elongated flat cuboid, which is advantageous parallel to its width with a Having a plurality of channel-like and powdery insulating materials Cavities are provided.
Die Hohlräume sind zweckmäßig wabenartig angeordnet, durch eine gewisse Stärke aufweisende Wände voneinander getrennt und zumindest an ihrem einen Ende durch einen einstückigen Boden verschlossen. The cavities are expediently arranged like a honeycomb, by a walls having a certain thickness separated from one another and closed at least at one end by a one-piece bottom.
In der Zeichnung ist der neue Formstein in einem Ausführungsbeispiel und in verkleinertem Maßstab dargestellt. Bs zeigen In the drawing, the new molded block is shown in one embodiment and on a reduced scale. Bs show

Der für einen Trichteraufsatz für Stahl- oder Graugußhersteilung bestimmte Formstein besteht aus einem quaderförmigen Körper aus feuerfestem Material. Im Gegensatz zu den bisherigen, einen vollwandigen Körper bildenden Steinen ist der neue Formstein mit einer Mehrzahl von Hohlräumen.1 versehen, die parallel zu den Seitenflächen 2,3 verlaufen. Und zwar sind, wie aus lig.i ersichtlich, in der Steinoberfläche 4 drei im Abstand parallel nebeneinander liegende Lochreihen vorgesehen, wobei gemäß Pig.2 die einzelnen Löcher 1 eine begrenzte und bis zu der Bodenfläche 5 durchgehende 'Hefe haben. Wie in Pig.4 dargestellt, sind die Löcher 1 mit einem geeigneten, vorteilhaft pulverförmigen und wärmeisolierend wirkenden Stoff 6 gefüllt. Das Isolierpulver 6 kann bereits vor Versand der Steine eingefüllt sein. In diesemThe one for a funnel attachment for steel or gray cast iron production Certain shaped brick consists of a cuboid body made of refractory material. In contrast to the previous one, a full-walled one For body-forming stones, the new shaped stone is provided with a plurality of cavities. 1, which are parallel to the side surfaces 2.3 run. As can be seen from lig.i, Provided in the stone surface 4 three rows of holes lying parallel to one another at a distance, wherein according to Pig.2 the individual holes 1 have a limited yeast that extends to the bottom surface 5. As shown in Pig. 4, the holes are 1 filled with a suitable, advantageously powdery and thermally insulating substance 6. The insulating powder 6 can be filled in before the stones are shipped. In this
Fall sind die Löcher 1 durch eine ggf. entfernbare Abdeckung/verschlossen, die einen vorzeitigen Verlust von Isoliermaterial verhindert. Die Hohlräume 1 können auch über die ganze Breite durchgehend, also oben und unten offen sein und ggf. durch beiderseits vorgesehene Abdeckwände 7 etwa gemäß Pig.4 verschlossen sein.In this case, the holes 1 are closed by a possibly removable cover /, which prevents premature loss of insulation material. The cavities 1 can also be continuous over the entire width, that is, be open at the top and bottom and, if necessary, be closed by cover walls 7 provided on both sides, for example in accordance with Pig.4.
Die wesentlichen Merkmale des Neuerungsgegenstandes bestehen darin, einen insbesondere fur i'richteraufSätze bestimmten Formstein geschaffen zu haben, der nicht nur in einfacher Weise angefertigt werden kann, sondern auch gegenüber den bisherigen, dem gleichen Zweck dienenden Formstein sich durch eine erheblich erhöte Wärme-Isolierfähigkeit auszeichnet und mit Sicherheit ein vorzeitiges Erkalten der im Trichteraufsatz befindlichen Gußmasse verhindert. Ein weiterer Vorteil besteht darin, daß die neuen Formsteine zunächst ohne Isolierstoffeinfüllung gestapelt und auch versandt werden können, wobei das Isolierpulver bei oder während des Aufbaus der Trichteraufsätze in einfacher Y/eise nachgefüllt werden kann. Die Erfindung ist nicht auf das dargestellt Beispiel beschränkt, sondern es sind hinsichtlich Zahl, Form und Anordnung der Löcher 1 andere Ausführungen möglich.The main features of the innovation are: a shaped stone especially intended for judge attachments to have created, which can not only be made in a simple way, but also compared to the previous ones, the same Purpose-serving shaped stone is characterized by a significantly increased heat-insulating capacity and prevents premature cooling of the casting compound located in the funnel attachment. Another advantage is that the new shaped bricks initially Can be stacked and also shipped without filling of insulating material, with the insulating powder during or during assembly the funnel attachments can be refilled in a simple Y / eise. The invention is not limited to the example shown, rather, other designs are possible with regard to the number, shape and arrangement of the holes 1.
