  • What Is A Rolling Mill? | Metal Processing Machinery

    Roll stands, holding pairs of rolls, are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (Ibeams, angle stock, channel stock, and so on), bar stock, and rails. Most steel mills have rolling mill divisions that convert the semifinished casting products into finished products.

     · I'm just about finishing up a cart for my welder and I used some hot rolled sheet for the shelves. The mill scale is pretty difficult to sand off and it seemed to really protect the steel from rust.

  • Hot Rolled Steel Cold Rolled Steel

     · The metal is rolled to the thickness of .3 mm in case of mild steel and .5 mm in case of stainless steel. The material is cooled by the use of oil which also acts as a lubricant during the rolling process. As the metal sheet gets thinner between the rolls, its speed increases. That would mean material wear and deformation if an oil film wasn't there to minimise the contact ...
