Abstract
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).
Claims11
Walking-beam furnace for the accelerated heating of billets or the like comprising mobile beams and fixed beams, said mobile beams and fixed beams having upper surfaces 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 axis as they advance through the furnace, characterized in that 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') by means of studs (13) and provided with thermal expansion joints therebetween;
- said ridge segments being removably fixed on the top of the beam by means of studs (13), being fixed on tubular beams in the form of square tubes which form the pipes through which the assailant fluid passes and which are provided on the top of the structure of the beam, and being provided with complementary reciprocal positioning means.
