1. Steel plant for the production of long metal products, comprising a continuous casting machine and a rolling mill disposed contiguous and in direct succession downstream of the continuous casting machine, in which the continuous casting machine is provided with at least two casting lines and the rolling mill is provided with at least two rolling lines, wherein each casting line is aligned with a respective rolling line defining overall at least two co-rolling lines disposed adjacent along respective work directions, said plant comprising a single feed apparatus for feeding molten metal, said at least two casting lines being configured to receive molten metal from said single feed apparatus, and further comprising at least a central management unit connected at least to an extractor unit of each of said at least two casting lines (11a,11b) and to a regulation device to regulate the stream of molten metal from said feed apparatus (14) to a corresponding crystallizer of each of said at least two casting lines, said central management unit being configured to control independently and autonomously at least each extractor unit and each regulation device so as to selectively vary the casting speed of each casting line, independently and autonomously with respect to the at least one other casting line.
