While the finished product is of good quality, the surface is covered in mill scale , which is an oxide that forms at high temperatures. Skin-rolled stock is usually used in subsequent cold-working processes where good ductility is required. Also, one could have fairly high crown or wedge, but still produce material that is flat. In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes. The decrease in material thickness causes the material to elongate.
The slitting mill was adapted to producing hoops for barrels and iron with a half-round or other sections by means that were the subject of two patents of c. Rolling mills are often divided into roughing, intermediate and finishing rolling cages. The concept is similar to the rolling of dough. The starting material is a thick-walled ring. This is the case when the frictional force on the metal from inlet contact matches the negative force from the exit contact.
