ABSTRACT:
A furnace for heating pipes each having an upset portion at least at one of its opposite ends includes a housing defining a heating chamber filled with high temperature gas, and a conveying apparatus for sequentially conveying the pipes in the housing in a direction perpendicular to an axial direction of the pipes. A blowing device is provided on one side of a path of the upset portion, and a waving plate is provided on the other side of the path, whereby the upset portion, when passing through a space between the blowing device and the plate, is heated locally by the high temperature gas blown out from the blowing device and also by the reflected high temperature gas and radiant heat from the plate.
