The 2nd & 3rd pic are of a 56" hot strip mill "emptied" housing stand, one of 6 finishing mills in a row. You can see the "spindals" they are basically big driveshfts. I just retired from the mill. It took 25 ton "slabs" of steel, 9" thick, up to 56" inches wide 28' long and turned them into "coiled" steel. I am practicing posting pics here because I am having trouble posting on a Steel Mill forum. Trying again! <a href="http://s119.photobucket.com/albums/o132/Kennybill/?action=view¤t=LookingintoRolllessFinishMilldrivespindalsandpinionstandshowing.jpg" target="_blank"><img src="http://i119.photobucket.com/albums/o132/Kennybill/LookingintoRolllessFinishMilldrivespindalsandpinionstandshowing.jpg" border="0" alt="Photobucket"></a>
