Embodiment Construction

[0045] figure 1 Shown is a glass-ceramic component 10 which has two sides 11 a , 11 b which are connected in one piece to one another by means of a corner 14 . The two sides 11 a , 11 b enclose an opening angle α on the inner side of the glass ceramic component 10 . On the outer side 13 , the glass-ceramic component 10 forms a convex contour in the region of the corner 14 , which now has a constant radius of curvature r. The sides 11a, 11b have the same side lengths sL1, sL2.

[0046] in accordance with figure 2 In the exemplary embodiment shown, a glass-ceramic component 10 is shown which has three sides 11a, 11b, 11c with side lengths sL1, sL2, sL3. The sides 11 a and 11 c are connected to the sides 11 b at the end sides by means of corners 14 . Between the sides 11 a , 11 b , 11 c an opening angle α is enclosed in each case in the region of the inner side 12 , wherein the opening angle α is now the same. The bending radius r at the corner 14 again results on the outsi...

Abstract

The invention relates to a method for creating a glass ceramic component (10) having at least one angle (14), wherein the angle is formed as a transition between two legs (11a, 11b). Very good surface qualities can be created in a simple manner in the region of the angle (14) wherein the angle (14) is made having a bending radius in the range between 30 mm and 200 mm during the ceramification process during conversion of the glass plate in a green glass state to the glass ceramic plate under the effects of a deformation tool. The invention further relates to a glass ceramic component (10) that is characterized by a particularly good visual quality.

Description

technical field [0001] The invention relates to a method for producing a glass-ceramic component with at least one angle, wherein the angle is formed as a transition between two sides. [0002] Furthermore, the invention relates to a glass-ceramic component with at least one angle arranged between two sides, the sides enclosing an opening angle. Background technique [0003] Glass ceramics are a special raw material that is produced from glass that has previously been melted in a melting tank and usually shaped into plates by targeted and temperature-controlled crystallization, the so-called keramisierung become. Unique properties of glass ceramics are high thermal shock resistance and very low thermal expansion. Glass ceramics are used, for example, in stoves as cooktops, as furnace linings, as cover plates for radiant heaters, as inspection windows for all stoves for heating, as inspection windows generally in combustion plants up to vehicles Observation windows, which ...
