ABSTRACT:
A pusher-type furnace for heating slabs is disclosed having lift rails in its soak zone for periodically raising slabs out of contact with skid rails along which the slabs travel through the furnace. The controlled raising and lowering of the lift rails in the soak zone alternates with extraction of slabs from the furnace discharge end and pushing of slabs along the skid rails, and reduces or eliminates soak zone skid marks on the bottom surface of the slabs without the need for a soak hearth. The lift mechanism comprises an open structure of rails and supporting members to facilitate heating as well as soaking of the slabs in the furnace soak zone, thus promoting efficient use of fuel.
