    In a wire rod mill, the performance in term of rolled output plays a vital role in the bottom line of the organisation. In the rolling system, raw material (in block form) is fed one after one, after adequate heating. Then the heated material is drawn by a series of roller and the output is collected through a conveyor, in a coil form.
