Oct 08, 2014· The takeup roll on the Sendzimir mill also exerts a tension on the coil as it comes through the mill. The combination of high pressure and tension makes the mill capable of rolling material thin and flat.
hot rolling mills. We thus consider tandem rolling mills equipped with loopers in this paper. Due to their easy setup, PI force controllers are still the most prevalent controllers for the position of looper rolls (Choi et al., 2007b). More advanced control systems use tension meters (Zhao et al., 2008) to measure the current strip tension.
Oct 18, 2017· Next type of rolling mill is three high rolling mill. In this type of rolling mills, three rollers are used one over the other in a vertical line. We can pass the ingot between first two rollers ...
The mill stand can be work roll driven or back up roll driven. The mill can be designed with hydraulic work roll bending and/or back up roll bending. Installations typically have a single rolling mill stand, but may have two. Pinch rolls provide back tension for the pay off reel in the entry section and entry and exit tension for the temper pass.
HOT LIQUID MILL METAL FEED Continuous Strip Casting Line Final sheet properties for the work hardening alloys in the 1000, 3000 and 5000 series are achieved either by temper rolling or temper annealing. In the former case the strip is reduced by a fixed amount of cold work to achieve the required temper, in the latter it is
Tags Pickle Lines, Rolling Mills; Temper Pass or Skin Pass Rolling. Material can be reduced accurately while skin passing. Hot rolled steel coming from a steel mill or pickle line may need to be reduced 1% to 2% in thickness. This can be done on a coiltocoil temper pass mill or in line on a cutto length line.
The science behind the temper mill involves compression, or rolling, the stainless through what is known as a cold reducing process, temper pass. This increases the density of the steel by reducing its overall thickness by around % to 2%, consequently, not .
The temper rolling mill imparts required surface roughness and appearance, and limits yieldpoint elongation by a controlled compression and elongation of the steel sheet. The tension leveler extends the steel sheet over bending rolls to produce superior flatness – vital for the efficient fabrication of lightweight automotive parts.

The mill stand can be work roll driven or back up roll driven. The mill can be designed with hydraulic work roll bending or back up roll bending. Installations typically have a single rolling mill stand, but may have two. Pinch rolls provide back tension for the pay off reel in the entry section and entry and exit tension for the temper pass.
Oct 25, 2019· A temper mill is a finishing facility that processes steel in the form of sheet and plate in order to give it added strength and uniform flatness to the surface. The metal forming method at a temper mill involves rolling the sheets of steel through what is known as a cold reducing process or temper .
JX is a global corporation specializing in designing, manufacturing, installing and commissioning metallurgy machineries and electronic control equipments such as pickling line, 4Hi cold rolling mill, 6Hi cold rolling mill, continuous hot dip galvanizing line, temper mill, continuous hot dip galvalume line, color coating line, bar production ...
mm Production line of Temper mill . 1. Brief introduction . The temper rolling process is performed to improve the sheet flatness, to remove yield point elongation and to impart a uniform surface on the sheet. For these reasons, applications requiring good flatness or surface must be temper rolled. 2. Technical Data of 750mm 4hi temper mill
All rolling units (skin pass, reduction, and temper mill), which are operated with stateoftheart ANDRITZ inhouse electrics and automation, are equipped with correspondingly fast and automated roll change equipment, integrated bridle rolls, advanced strip drying, and .

60 YEARS OF ROLLING MILL TECHNOLOGY ... When most people think of a rolling mill, they visualize sizable machinery in ferrous (iron, carbon steel and stainless steels) and nonferrous (copper, brass, lead, etc.) integrated or electric arc furnace (EAF) ... including hydraulic screwdowns, hydraulic roll bend, and tension control.
very small slip in the roll bite, (e) temper rolling can yield the entire work piece while the tension leveler cannot reach the central portion of the material, and (f) for tworoll driven mill ...
Temper Rolling (also called skin pass rolling, or dressing), in engineering, a finishing operation in the production of thin strips of steel and nonferrous metals. It consists of cold rolling with very low reduction of area (not more than 3 percent). As a rule, the metal is subjected to temper rolling after heat treatment. Temper rolling increases the ...
Jul 08, 2019· Temper / Skin Pass Mills The device uses skin pass rolling to improve the mechanical properties and surface texture, and improve flatness, in order to form materials such as hotrolled steel sheets, coldrolled steel sheets, stainless steel plates, and aluminum plates into final products.
The most common configuration is a single skinpass mill that rolls in a single direction, with tension reels placed at both ends of the mill. However other types are also used, such as a temper mill with two mill stands for higher tempering in tinsheet production mills which include DCR (Double Cold Reduction) mills with two or even three ...
