Abstract

The invention relates to furnaces and in particular solid hearth walking beam furnaces and support beams thereof. The support beam has a billet support surface (11) raised above an upper refractory layer (19) and extending longitudinally along the beams. The support surface, along most of its length, is narrower than the beams to achieve as even and rapid a heat input to the billet as possible and has along part of its length a meander or zigzag, such that the area of contact on the underside of the billet is changed each time a walking beam stroke is effected. The support surface may be defined by lateral surfaces (21, 22) extending at an angle to the upper refractory layer, the angles varying along the length of the support surface by virtue of the meander of the latter. Scale shedded from the billet during operation of the furnaces is caused to move along the angled surfaces into specific areas where arrangements can be made to collect and dispose of the scale. <IMAGE>
