Refractory, heat-insulating wall structural part

摘要

In the case of a refractory, heat-insulating wall structural part, an inner core 2 consisting of ceramic fibre material is introduced into a dimensionally stable shell 1. In order to achieve the strength and chemical resistance of a dense-graded, refractory building material and the thermal conductivity of a fibre insulation, only the inner core 2 is constructed from mats or panels of ceramic fibres and the shell 1 consists of castable refractory concrete or ceramic. The cuboidal shell 1 has four or five closed side walls. <IMAGE>
