ABSTRACT:
A method of processing steel slabs in which the slabs are continuously routed through a furnace to a slabbing mill the slabs being sequentially charged through the bottom of the furnace by a reciprocating mechanism whereby on the upward stroke the slab charged engages and lifts the slabs piled above it and is then securely held (via jaws) until engaged itself in the next cycle by the succeeding slab. The top slab is discharged during each cycle whereby the number of slabs in the pile in consistent and all are heated on their exposed surfaces during their period in the furnace.
This invention maximises the use of the residual heat from the cast slab where `sizing` is to be performed.
