Abstract

Bei einem Verfahren zur Fertigung von im Profil im wesentlichen L-förmigen mit zwei unter einem Winkel von etwa 90° aneinandergrenzenden Schenkeln (2) ausgebildeten keramischen Formsteinen, deren Schenkellänge mindestens das Zehnfache der Schenkeldicke beträgt, insbesondere von Randsteinen (11) für Tunnelofen-Brennwagen, wobei eine keramische Masse aus Feuerfestkeramik zu einem Grundkörper (1) geformt wird, der getrocknet und gebrannt wird, erfolgt das Formen der Masse erfindungsgemäß durch Extrudieren bzw. Strangpressen in die Form eines im wesentlichen rechteckigen Hohlprofils, das in der gewünschten Steinlänge abgelängt und nach dem Brand im Bereich zweier sich gegenüberliegender Ecken (6) in Längsrichtung (7) aufgetrennt und in einzelne Formsteine geteilt wird. Vorzugsweise wird im Bereich der später nicht aufzutrennenden Ecken (8) des Grundkörpers (1) mehr keramische Masse als an den übrigen Schenkelbereichen des Grundkörpers (1) ausgepreßt. Insbesondere können beim Pressen jeweils zwei benachbarte Schenkel (2) des Grundkörpers (1) im Bereich der nicht aufzutrennenden Ecken (8) durch Stützrippen (9) zusätzlich verbunden und in ihrem Winkel zueinander fixiert werden. Ein unter Verwendung derartiger Formsteine hergestellter Tunnelofen-Brennwagen wird ebenfalls beschrieben.

In a process for the production of essentially L-shaped ceramic shaped stones with two legs (2) adjoining each other at an angle of approximately 90 °, the length of the legs of which is at least ten times the leg thickness, in particular of curbs (11) for tunnel kiln kiln cars , wherein a ceramic mass made of refractory ceramic is formed into a base body (1) which is dried and fired, the mass is shaped according to the invention by extrusion or extrusion into the shape of an essentially rectangular hollow profile which is cut to length in the desired stone length and after the fire in the area of two opposite corners (6) is separated in the longitudinal direction (7) and divided into individual shaped blocks. Preferably, more ceramic mass is pressed out in the area of the corners (8) of the base body (1) that cannot be separated later than on the other leg areas of the base body (1). In particular, two adjacent legs (2) of the base body (1) can be additionally connected in the area of the corners (8) that cannot be separated by supporting ribs (9) and their angles fixed to one another. A tunnel kiln car made using such shaped bricks is also described.
