Abstract
Cold rolled material manufacturing equipment comprises: an unwinding device for unwinding a hot rolled coil after acid pickling; joining means, disposed on the exit side of the unwinding device, for joining the tail end of a preceding coil to the leading end of a succeeding coil unwound from the unwinding device; a rolling mill for continuously rolling the coils in one direction; a strip storage device, disposed between the joining means and the rolling mill, for storing a strip to perform continuous rolling during the joining; a strip cutting device for cutting the strip to a desired length; a winding device for winding the rolled coil; transport means for transporting the coil to the unwinding device so that the coil is rolled a plurality of times; and a rolling speed control device for controlling a rolling speed during the joining to a lower speed than a steady rolling speed.
