24 three roll tension reducing machines

The tension reducing machine adopts 24 sets of three roll separate transmission tension reducing machines, whose main function is "fixed diameter+tension reducing wall". It uses AC frequency conversion speed regulation and tension adjustment to achieve head and tail wall thickness control function, solving the world-class problem of "head and tail thickening" that cannot be controlled, reducing cutting loss, and increasing metal yield by 5%.

By using tension control, the length of the rolling line was reduced, and multi specification production of 60-180mm was achieved under one type of billet.
