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 (22) continuously receives an as- continuously cast endless slab of steel (19) or ferrous metal and effects a first reduction in thickness from the as-continuously cast thickness of the slab, a plurality of millstands (70, 72, 74, 76) sequentially receive the continuous strip (19) from the Platzer plane- tary mill (22) 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 (78, 80, 82) are placed between each adjacent pair of millstands (70, 72, 74, 76) to maintain the continuous strip (19) at a working temperature sufficient to effect the second reduction in thickness.
