The diameter of the 6high work rolls amounts to approximately 1:4 in relation to the barrel length. In comparison to a 4high mill stand, the utilization range is wider. This type of rolling mill is mainly used in offline applications for cold rolling of soft and medium strip and for a wide range of strip widths.
A fresh fracture shows a clear bluish color with a high silky luster and fibrous appearance. Wrought iron lacks the carbon content necessary for hardening through heat treatment, but in areas where steel was uncommon or unknown, tools were sometimes coldworked (hence cold iron) in order to harden them.

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semifinished casting products, such as slabs, blooms, and billets.
Fourroller mills Fourroller mills have two sets of rollers. When using a fourroller mill to mill grain, the grain first goes through rollers with a rather wide gap, which separates the seed from the husk without much damage to the husk, but leaves large grits.
