Abstract

In the walking beam furnaces, in order to heat metallurgical materials such as billets, bars and the like, having different temperatures of introduction into the furnace and/or different cross sections, so as to discharge materials at uniform temperatures from the furance, said materials are selected according to their temperature and/or cross section, and are introduced into the furnace through a plurality of side inlet doors while said materials are conveyed along the furnace by means of an external side conveyor, and/or they are discharged from the furnace through a plurality of side outlet doors and are then advanced outside along the furnace by means of an external side conveyor. The external side conveyor can be formed by a walking beam conveyor, timed with the internal walking beam conveyor as to the length and rate of steps, and/or timed in relation therewith so that at each occupied position on the external walking beam conveyor always corresponds an unoccupied position on the internal walking beam conveyor, and vice versa. The external conveyor can be enclosed in a chamber which, if desired, is insulated and is associated with heating means such as the exhaust gases discharged from the furnace.
