| Coils are removed from storage and placed on a feed ramp. Here
each coil is positioned on the center line of the mill and fed into the
uncoiling unit. The leading edge feeds into the pinch rolls preceding the
flattener. An electrically operated shear cuts off the end of each coil
so that the coils can be welded together to form a continuous strip. |
The first forming section, composed of breakdown
strands, begins the transformation of the strip from flat steel to a round pipe section. The
roll transition section receives the product from the first forming section and continues
the "rounding-up" process. |
The section of
the forming rolls finishes the rounding process and
contours the edges of the strip for welding. |
