ABSTRACT:
A continuous process and system for making flat rolled steel or ferrous metal strip having a minimum thickness sufficient to allow substantially direct product manufacture therefrom, wherein a Platzer planetary mill continuously receives an as-continuously cast endless slab of steel or ferrous metal and effects a first reduction in thickness from the as-continuously cast thickness of the slab, a plurality of millstands sequentially receive the continuous strip from the Platzer planetary mill to effect a second reduction in thickness of at least about 50% of the first reduced thickness to provide a continuous strip having an average thickness of less than about 1.8 mm, and electric induction reheaters are placed between each adjacent pair of millstands to maintain the continuous strip at a working temperature sufficient to effect the second reduction in thickness.
