May 22, 2019· The half-products are then fed to cold reduction mills. The metal is rolled to the thickness of 0.5…3 mm in case of mild steel and 0.5…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.
Extruded T6 is called T6511 – "Solution Heat-Treated, Artificially Aged, Permanent Set and Straighten" The final digit in the -T6511 designation (and how I know it was an extrusion, since this only applies to extruded stock) means that the aluminum mill is allowed to straighten the extruded bars, like in a press, to get the material to ...
Mar 16, 2016· Coiling – Coiling is the process of winding flat material while it is still hot.As it exits the extrusion rollers at the mill immediately after it has been formed. Coils – Sheet metal rolled from slab or ingot that has been wound into coiled roll.Coils are considered the most efficient way to store and transport sheet metal.
