Abstract

1. Muffle for furnaces geared to continuous or pusher type principles of operation for the heat treatement of materials under protective furnace gas with a stretched heat-resistant shell casing provided with an opening at one end at least, distinguished by the shell casing revealing an internal body (7) consisting of ceramic enclosed by sheet-metal sheathing (8).
