The invention relates to a compact wire and bar rolling
production line which sequentially comprises a
heating furnace, a rough rolling unit, an intermediate rolling unit, a finish rolling unit and a collecting
system. The collecting
system comprises at least one of a cooling
bed, a coiling and collecting
system and a wire collecting system. The rough rolling unit, the intermediate rolling unit and the finish rolling unit are respectively provided with a Y-type three-roll
rolling mill and an
inverted Y-type three-roll
rolling mill, and the Y-type three-roll rolling mills and the
inverted Y-type three-roll rolling mills are distributed in an alternating mode. A rolling
machine set adopts the three-roll rolling mills of the same structural mode, the rolling
machine set is universal, a wire and bar collecting system can be flexibly distributed, and flexibility of wire rolling is high. A high-speed steel feeding system is arranged so as to increase
rolling speed of the rolling
machine set and improve production efficiency, the
brake sliding distance between high-speed rolled workpieces is shortened, the rolling length is further shortened, and investment is reduced. An arranged wire reducing
sizing rolling unit further rolls and produces wires, and facilitates improvement of rolling quality of the wires and size precision of products.
