Description

Verfahren zur Herstellung feuerfester Zustellungen Im Patent 433 715 sind feuerfeste Zustellungen für Herde metallurgischer und anderer üfen geschützt, deren Form mit Hilfe einer Schablone hergestellt wird, die im Herd belassen und bei der ersten Schmelze mit c#iiil;esclrmolzen wird. Hierbei wird ein trokkener, körniger, feuerfester Stoff von der Seite der Beschickung her gesintert und dabei formbeständig, ehe die Schablone zum Schmelzen kommt.Process for the production of refractory linings Refractory linings for stoves of metallurgical and other ovens are protected in patent 433 71 5 , the shape of which is produced with the help of a template that is left in the oven and is melted with c # iiil; esclrmolten during the first melt. Here, a dry, granular, refractory material is sintered from the side of the charge and thereby retains its shape before the stencil melts.

Es hat sich nun gezeigt, daß, in gleicher Weise wie Ofenherde mit besonderem Vorteil auch Deckengewölbe hergestellt «erden können. Dabei geht man in der Weise vor, daß inan für das Deckengewölbe eine Metallschablone herstellt, die die nach dem Ofeninneren zugewendete Seite des Gewölbes bilclet. Auf diese Metallschablone füllt man den ker.unischen Werkstoff, der das Gewölbe bilden soll. Wenn man dann auf beliebige `'eise den Ofenherd erhitzt, dann wird voll dem Ofenherd und dem Ofeneinsatz so viel Wärme gegen. die das Deckengewölbe nach innen abschließende Metallschablone gestrahlt, daf.@ der keramische Werkstoff hinter der Schablone sintert. Solange er noch nicht -wintert ist, kommt auch die Schablone noch nicht zum Schmelzen. Sie fließt vielmehr erst dann ab, wenn ebenso -wie bei der durch das Hauptpatent geschützten Herstellung der Herde der keramische Werkstoff bis zu einer gewissen Tiefe gesintert ist. Die Herstellung der Ofengewölbe auf die geschilderte Art hat noch den Vorteil, daß man die Schicht des keramischen Werkstoffes so dick wählen kann,- daß auch bei den höchsten, während des Betriebes im Gewölbe auftretenden Temperaturen die :äußersten Schichten urigesintert bleiben. In urigesintertem Zustand ist die Wärmeleitfähigkeit schlecht und infolgedessen die Wärmeisolierung durch das Deckengewölbe sehr gut.It has now been shown that, in the same way as stove stoves with It is particularly advantageous that vaulted ceilings can also be produced. Here you go in such a way that inan produces a metal template for the ceiling vault, which bilclet the side of the vault facing towards the inside of the furnace. On this metal template one fills the Ker.unischen material that is supposed to form the vault. If you can then Heat the stove in any way, then the stove and the stove insert will be full so much warmth against. the metal template that closes the vaulted ceiling inwards sandblasted so that @ the ceramic material sinters behind the template. So long If it is not yet winter, the stencil has not yet melted. she Rather, it only flows out if, as in the case of the one protected by the main patent Manufacture of the hearth of the ceramic material sintered to a certain depth is. The production of the furnace vault in the manner described has the advantage of that you can choose the layer of the ceramic material so thick, - that also with the highest temperatures occurring in the vault during operation: the extreme Layers remain sintered. The thermal conductivity is in the originally sintered state bad and as a result the thermal insulation through the vaulted ceiling is very good.
