Abstract

A Conveyor furnace for firing pipe-shaped objects with the following characteristics:1.1.1 a furnace floor,1.1.2 a furnace ceiling,1.1.3 a two lateral furnace walls, which connect the furnace floor with the furnace ceiling, forming a furnace channel,1.2 the furnace floor has at least one opening running in the axial direction of the furnace channel,1.3.1 at least one transport unit that extends from a motor section below the furnace floor through the opening to a transport section in the furnace channel, and1.3.2 which can be driven along the opening,1.4 the transport section is designed to hold, in a horizontal position, at least one pipe-shaped object,1.5 in the furnace channel below at least one part of the object to be fired, which is freely achievable, a device is arranged, onto which the object first rolls up, with its freely achievable part, and then rolls down.
