Abstract: In a heating furnace 10 where elongate workpieces fed into the heating furnace are sequentially transferred on fixed beams by walking beams from an inlet area to an outlet area, concaves to retain the workpieces are formed at least on the walking beams. A concave in the inlet area for heating the workpieces is increased in width in a transfer direction, while a concave in the outlet area where the heated workpieces are wholly heated to a uniform temperature and retained in position is formed in a corrugated configuration. Despite curving of an elongate workpiece being heat treated as transferred by walking beams in a direction crossing a longitudinal direction of the workpiece, this ensures that the curved workpiece is properly transferred and adequately corrected for the curving.

Abstract: Steel charges are heated to rolling temperature in reheating furnaces. It is standard practice for the charge to be moved through such a furnace on continuous water-cooled tubular supports crossing the furnace in a straight line. The supports obstruct charge heat-up to the desired temperature at the points where the charge is in contact with the tubular supports. A lateral offset of the tubular supports or similar designs have been unable to overcome this disadvantage. The tubular supports of the present reheating furnace are therefore several times offset from a straight line through the furnace between the furnace inlet and the furnace exit or, in the case of a furnace with a fixed hearth in the soaking zone, the furnace inlet and the fixed hearth. Each tubular support section between two such offsets is shorter than the upstream tubular support section. The present arrangement is particularly advantageous for pusher-type furnaces or walking-beam furnaces.

Abstract: A walking beam furnace comprises a hearth formed by fixed and walking beams disposed with their axes in the feed direction. Both the walking beams and the fixed beams are divided at positions spaced apart in the feed direction into sections, and each section of each beam is staggered relative to the adjacent section. As a result, the material to be annealed comes into contact with the cooled fixed beams at different positions at each of the conveying pauses and temperature balancing takes place at the points of contact.

Abstract: A top-fired, lifting or walking, hearth-type furnace includes an upstream preheating zone and a downstream primary heating zone. Stock, such as billets or ingots, to be heated is passed sequentially through the preheating zone and primary heating zone. Each zone has therein support members for supporting the stock. The support members of the preheating zone are at a level higher than the support members of the primary heating zone, with a step therebetween, whereby hot flue gases in the preheating zone circulate upwardly around the support members therein and the stock supported thereby. A lowering and lifting apparatus is located at the step to transfer stock from the support members of the preheating zone to the support members of the primary heating zone.
