<p>Walking-beam furnace for the accelerated heating of billets or the like, in which the upper surfaces of the mobile beams (1) and of the fixed beams (1') are made up of billet-tipping ridges (5, 4) having profiles which interact during operation so as to cause rotation of the billets about their longitudinal axes as they advance through the furnace. According to the invention, the billet-tipping ridges (4, 5) of the fixed beams (1') and of the mobile beams (1) consist of a plurality of modular elements (7, 8, 9, 10) in the form of billet-tipping ridge segments which are mutually aligned along the length of the beams (1, 1'). The ridge segments (7, 8, 9, 10) have additional features which improve operation of the billet-tipping ridges (4, 5). <IMAGE></p> |
