In a previous article, we briefly outlined rolling mills, and the different types. In this article, and one to follow, we will go into more depth on the differences of each. The focus will be on the two-high pull over mill, two-high reversing mill, and the three-high rolling mill. At American Steel, we believe understanding the differences will help our customers make the correct choice for their specific needs.
It has been suggested that Leonardo Da Vinci invented the first rolling mill, but what exactly is a rolling mill? Rolling mills are units in which a metal forming process takes place. During this process various metal materials get passed through a massive pair of rolls, or material handling equipment.
Stainless steel can corrode in service if there is contamination of the surface. Pickling and passivation are two forms of chemical metal finishing that provide protective properties to the metal especially against rust. In other words, pickling and passivation are the names of the two processes where the metal is submerged in a bathing liquid that removes imperfections and rust from the surface of metal.
Embossing rolling mills are simply rolling mills that will create patterns or indents into metal strips. The patterns can be decorative, or help with the structural qualities of tubing, or to simply increase the strength of the material length without any significant decrease to the material thickness for additional cost effectiveness.
