Abstract:
A method of substantially uninterrupted continuous casting of thin metal slab followed by entry at optimum speed into a hot-rolling mill for producing superlarge coils of continuous length hot-rolled strip, comprising:continuously casting an elongated thin metal slab, reheating said slab to about a temperature for hot-rolling and rolling the thin cast slab in a roughing mill to reduce its thickness gauge,coiling to form a first superlarge coil of said reduced thickness gauge continuous slab at a coiling station having positioned therein a first coil handler for supporting, coiling and uncoiling superlarge coils, then, following completion of coiling,repositioning said first superlarge coil, supported by said first coil handler from the coiling station to an uncoiling station, while simultaneouslyrepositioning a second coil handler, positioned at the uncoiling station, to the coiling station for use in repeating said coiling step,uncoiling said first superlarge coil, for entry of reduced thickness gauge continuous slab into a hot-rolling mill,hot-rolling said reduced thickness gauge continuous slab to form hot-rolled strip, andcoiling said hot-rolled strip into a finished superlarge coil.
