Description

Rost zum Brennen von Emailwaren Roste zur Auflage der Gegenstände beim Einbrennen der Emaille werden zweckmäßig aus hochhitzebeständigen Legierungen hergestellt. Für diese Roste ist es wichtig, eine möglichst große Stärke bei Verwendung von möglichst wenig Material zu erreichen, und zwar aus Gründen der Wärmeersparnis -und des hohen Materialpreises. Zur Erreichung eines großen Widerstandsmomentes der Roststäbe sind naturgemäß Profilstäbe am günstigsten. Winkel- und U-Stäbe sind jedoch nicht zu verwenden, da diese Profile sich im Feuer ausweiten und ihre Stärke dann verlieren. Am günstigsten ist daher ein geschlossenes Rohr, und da die Roststäbe in vertikaler Richtung stärker beansprucht werden, ein ovales Rohr.Grate for burning enamel goods. Grates to place objects on When firing the enamel, it is advisable to use highly heat-resistant alloys manufactured. It is important for these grids to be as thick as possible when using them to achieve with as little material as possible, for reasons of heat saving -and the high material price. To achieve a large section modulus of the grate bars are naturally the most favorable profile bars. Angle and U bars are but not to be used, as these profiles expand in the fire and their strength then lose. It is therefore best to use a closed pipe, and then the grate bars are more heavily stressed in the vertical direction, an oval tube.

Für den Verwendungszweck eines Emaillierrostes hat ein glattes Rohr jedoch noch den Nachteil, daß es eine breite Auflagefläche besitzt.For the purpose of an enamelling grate has a smooth tube however, it still has the disadvantage that it has a wide contact surface.

Gegenstand vorliegender Erimdung ist eüi Rost, dessen Roststäbe aus Rohren bestehen, die eine scharfe Auflagefläche besitzen. Ein Ausführungsbeispiel für einen solchen Roststab ist in der Zeichnung im Querschnitt dargestellt. Wie aus der Zeichnung hervorgeht, werden die Roststäbe aus Blechen geformt, und zwar so, daß zur Erreichung einer schmalen Auflagekante in der Längsrichtung eine Seite des Rohrbleches in beliebiger Höhe übersteht. Die Anordnung scharfer Auflagekanten an Brennrosten zum Auflegen der zu brennenden Emailwaren ist an sich bekannt und daher nicht Gegenstand der Erfindung.The subject of the present earth is eüi rust, its grate bars from There are pipes that have a sharp contact surface. An embodiment for such a grate bar is shown in cross section in the drawing. As As can be seen from the drawing, the grate bars are formed from metal sheets, namely so that to achieve a narrow support edge in the longitudinal direction one side of the pipe sheet protrudes at any height. The arrangement of sharp support edges on grates for placing the enamel goods to be fired is known per se and therefore not the subject of the invention.

PATENTANSPRUCH: Rost zum Brennen von Emaii1waren mit schmaler Auflagekante für das Brenngut, dadurch gekennzeichnet, daß die Roststäbe aus runden oder ovalen Rohren bestehen, die so geformt sind, daß zur Erreichung einer schmalen Auflagekante in der Längsriclitung eine Seite desRohrbleches in beliebiger Höhe übersteht. PATENT CLAIM: Grate for burning Emaii1waren with a narrow supporting edge for the items to be fired, characterized in that the grate bars consist of round or oval tubes which are shaped so that one side of the tubular sheet protrudes at any height to achieve a narrow supporting edge in the longitudinal direction.
