ABSTRACT:
The invention relates to a process and to an installation for the heat treatment of cylindrical bodies, in particular pipes, of ceramic material. During the treatment, the pipes are dried, heated and sintered, and subsequently cooled, in successively arranged chambers.
During transportation through the drying zone, the heating zone and the cooling zone, as well as in heat treatment during sintering, the objects are turned about their own axis independently of the transportation rate, so that they are not only evenly heated, but a possible deformation is also prevented. This type of transportation and heating with possible heat exchange between the individual zones makes possible a rapid heating-up without detriment to the cylindrical bodies, and thus a short design length of the installation. Above all, the sintering zone, which must consist of high-value, ceramic material due to the high temperatures, can be kept very small.
