21-01-2019· Modern, efficient cold rolling mills can roll pickled sheets or strips at speeds of up to 4 m/s and tandem mills that are continuously working can produce up to 2.5 million tons of cold rolled steel annually. The advantages of cold rolling.
Work Rolls High Speed Steel For Cold Mill. So, it is of great significance to develop new cold work rolls to meet the requirement for production and rolling mill consequently, the steels with high alloy element content for cold work roll are applied extensively, such as 3cr steel, 5cr steel, semi-high speed steel semi-hss and high speed steel hss, however, with the increment.
rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.

FH-11. 3% Cr Steel. Tandem Mill Work Roll. Reversing Mill Work Roll. Skinpass Mill Work Roll. General Use. FH-15. 5% CR Steel. Tandem Mill Work Roll.
Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill). The wear is uneven from one end of the barrel to the other.
Currently, work roll shifting mill is the most effective mill for strip shape control [12,13] ... and it can be used in the process control of strip cold rolling mill. View.
Mechanics of Cold Rolling of Thin Strip 443 where yiw is the vertical deflection of the work roll at element i, gijw (, ) is the influence function for the work roll deflection due to the combined bending and shear forces generated by rolling load, giwf is the influence function for the work roll deflection due to the force generated by the roll bending mechanism, k represents the minimum element
