This mill is increasingly used for stainless steel strip rolling, either as in-line tandem mill for cold rolling or in the entry section of hot-strip stainless steel annealing and pickling lines to roll black hot strip with highest pass reductions and simultaneous improvement of the strip shape.
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
Cold rolling of pickled strip. Cold rolling of pickled hot rolled strip is accomplished by processing steel strip through a rolling mill which has an entry end reel for uncoiling the pickled hot rolled coil and an exit end reel for coiling of the cold rolled strip. In between, there are one or more (normally up to 6 nos.) rolling mill stands ...

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.
The 4-hi rolling mill completes this process by working rolls. The work roll includes two kinds of motion: rotating and moving. The former is realized by the main drive of the rolling mill and the latter is used to adjust the reduction and control the deformation degree of the rolling piece, which is realized by the rolling mill screw-down device.
Primetals Technologies supplies stand-alone and inline skin-pass mills in either single- or two-stand design for adjusting the final mechanical properties, flatness and surface finish of cold-rolled strip.

FENN offers hot and cold Rolling Mill machines as well as combination mills that can accommodate both hot and cold rolling applications. Hot rolling is a process in which the metal is heated to above the recrystallization temperature, allowing the material to deform on a microscopic level and take its new shape.. ... Precision strip mills from ...
There are two types of rolling. With hot rolling, heated metal goes through a rolling machine where it is worked into a sheet or bar. With cold rolling, sheet steel is made thinner at normal temperatures, and its surface is made smooth and uniform. Tsubaki products are used in both hot and cold rolling.

Cold rolling mills. for reducing, skin passing and finish-rolling in 20-high, S6-high (18-high), 12-high, 6-high, 4-high, and 2-high designs, and in combinations of 2-high/4-high or 4-high/S6-high design, available as one-way, reversing or tandem mill, inline and offline. Shape control systems. for cold rolling mills and strip processing lines.
Cold-strip reduction mills. A tandem cold rolling mill usually consists of three to five stands of rollers, each of which reduces the strip thickness by about 20 to 40% so that the total reduction in one pass may be by a factor ten. It has long been recognized that some, if not most, of the variations in thickness of strip produced by a cold ...

It was put to practical use in the cold tandem strip rolling mills with the function for changing the cross angle through a strip threading. 112) In the cold strip rolling with the pair cross rolling mill, it is checked by the theoretical analysis that the thickness at the strip edge becomes thicker as the cross angle increases. 113) The logics ...
Cold rolling mill introduction: Cold rolling mill is used to roll raw material thickness ≤ 4 mm, width ≤ 800 mm, made of plain carbon steel, low alloy steel, stainless steel and non-ferrous metal strip, used for roughing or roughing mill.
The Detroit mill initially consisted of a small reversing hot rolling strip mill with a slab heating furnace. The original hot strip mill was known as the "Coffee Grinder" from the sounds the mill would make. In 1938, the company brought online a single 4-high reversing cold reducing mill with ancillary facilities (annealing and finishing).
