Abstract
The invention concerns a device () for sintering of a porous mold body () in a gas-tight chamber (), with the mold body () hanging loose from a link chain () so that it can be fed continuously to a heating zone (). In the area of the upper boiler (), the traction direction of the link chain () is reversed by a deviation wheel (). The tensile force is transmitted via a traction rope () that can be taken up on a take-up reel (), such take-up reel () being driven by a drive () arranged outside the chamber (). A drive shaft () for the take-up reel () provides for easy sealing of the duct () towards the chamber (), because only a rotation and not a simultaneous axial displacement is required for the hoisting movement, and moreover, because the duct () is arranged at a spatial distance from the heating zone (). The link chain () consists of carbon fiber reinforced mineral carbon materials and is thus resistant to high temperatures, so that no contamination of the mold body () by released components of the material of the link chain () will occur.
