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.
Research into plate elongation distribution between the tension leveler and temper mill for pickling line 2030 at Baosteel is conducted. The study, which involved performance testing of mechanics, is designed at different elongation distributions and analyzed from many aspects. Finally, the optimal elongation of the tension leveler and temper mill …

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 coil-to-coil temper pass mill …
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 hot-rolled steel sheets, cold-rolled steel sheets, stainless steel plates, and aluminum plates into final products. Since it conducted tests with its own test equipment ...
Thus, dry rolling is done in the first stand of a temper rolling mill comprising a plurality of rolling stands, and wet rolling is done in the subsequent rolling stands. Results of the rolling in an actual rolling mill (four-high two-stand tandem type) according …

corporation production mill. The computer simulation have been used to study chatters and showed the variation of natural frequency with variety of factors viz. friction, rolling speed, tension, reduction and strip width. The stability criterion for rolling mill was derived analytically using the factors causing negative and positive damping [8].

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 pass. This increases the density of the steel ...

A survey of tension control methods for rolling mills can be found in [5]. However, tension control in rolling mills is not directly comparable to tension control in slitting lines, since rolling ...
Reducing the roll gap increases the roll pressure to p3. Gage control in multiple rolling mills is achieved through measurement of strip thickness using x-ray gage and adjusting the strip tension using feedback control system. 1.8 Rolling defects: Mill spring is a defect in which the rolled sheet is thicker than the required thickness because,

Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham in Hampshire, England.In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was ...
Tension levelers are typically used for leveling material by stretching the material into the elastic region. In order to achieve the high amounts of tension necessary, a tension leveler can utilize bridle roll sets that incrementally increase the tension into the main leveling zone and incrementally decrease the tension to the downstream process or recoiled.
combination with tension leveling, the ratio of rolling tension can easily be modified while maintaining elongation to the target value and, therefore, obtain the desired quality.

In their setup, the desired strip roughness can be achieved by combination of different rolling forces on the two mill stands. However, most temper rolling mills use a single mill stand. In these cases strip tension might be an alternative, as it is widely adjustable and influences the transfer ratio via its effect on the roll pressure.
A light cold-rolling operation on a 2-High Temper Mill, skin passing may involve leveling, trimming or slitting and shearing to lenth. Skin-Passing allows material elongation of less than 1%, thus improving gauge, uniformity, flatness and surface hardness without compromising ductility or surface finish. Skin-Pass Temper Mills also
In the temper rolling of the steel sheet, when stopping a temper rolling mill from the state where the temper rolling is carried out, ... In the temper rolling method of the steel sheet, the exit angle of ≥18° is imparted on the outlet side of a temper mill and the tension on the delivery side of the temper mill is taken as ≥5.0 kgf/mm^2.
