Abstract
To improve the position of a cylindrical ceramic hollow body the invention relates to a securing device for use with a gas purging brick, where the securing device has 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.
