SECURING DEVICE FOR A CYLINDRICAL CERAMIC HOLLOW BODY AND FIREPROOF CERAMIC GAS PURGING BRICK HAVING SUCH TYPE OF SECURING DEVICE

摘要

To improve the position of a cylindrical ceramic hollow body the invention relates to a securing device with the following characteristics in its operational position: A base body which, with its bottom and a circumferential wall, defines a cylindrical space with a corresponding central longitudinal axis, the bottom features an opening whose longitudinal axis aligns with the central longitudinal axis the bottom features a ring-shaped channel which extends concentrically around the opening. at least an inner wall of the channel which is adjacent to the opening consists of a material which is plastically ductile under the application of pressure, a ring-shaped compact whose radial wall cross-section increases in size upwards from a lower free end, so that the inner wall of the channel deforms plastically, thereby reducing the cross section of the opening, after the compact is pressed into the channel.

1. Securing device for a cylindrical ceramic hollow body (SR) with the following characteristics in its operational position:
a) a base body (12) which, with its bottom (12B) and a circumferential wall (12W), defines a cylindrical space (12R) with a corresponding central longitudinal axis (M), b) the bottom (12B) features an opening (12O) whose longitudinal axis (L) aligns with the central longitudinal axis (M) c) the bottom (12B) features a ring-shaped channel (14N) which extends concentrically around the opening (12O). d) at least an inner wall (14I) of the channel (14N) which is adjacent to the opening (12O) consists of a material which is plastically ductile under the application of pressure, e) a ring-shaped compact (16) whose radial wall cross-section increases in size upwards from a lower free end (16U), so that the inner wall (14I) of the channel (14N) deforms plastically, thereby reducing the cross section of the opening (12O), after the compact (16) is pressed into the channel (14N).
