Abstract:
A method of manufacturing hot-rolled steel strips from a continuously cast primary material in a plurality of successive continuous steps, said method comprising the steps of:cutting off a thin slab of a pre-determined length corresponding to a desired coil weight from a solidified primary material;homogenizing the thin slab in a equalizing furnace;thereafter, heating the thin slab across an entire cross-section thereof to a temperature above 1150.degree. C. in a heater located downstream of the equalizing furnace;thereafter, breaking down the thin slab in a break-down train;recrystallizing the thin slab;thereafter, cooling the broken down thin slab to a rolling temperature;thereafter, finish-rolling the thin slab for producing a finish-rolled strip;cooling down the finish-rolled strip; andreeling the finish-rolled strip in an upcoiler.
