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 or in line on a cut-to length line.

the tention of temper rolling mill

The temper rolling mill imparts required surface roughness and appearance, and limits yield-point 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.

5. Cluster Rolling Mills: In this type of rolling mill, there are two basic roles that are backed up by two or more rolls which are bigger than those two basic rolls. These backed up rolls give more pressure to the basic rolls to heavily press the strip.

Rolling of Metals: Process and Principles (With Diagram)

The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

Temper mill - Wikipedia

Tandem cold rolling process is a nonlinear complex system with external and internal uncertainties and significant disturbances. The improvement in the quality of the final output depends on the control strategy of centerline thickness and interstand tension. This paper focuses on interstand tension control problem in 5-stand tandem cold rolling mills.

Tension Leveling and Skin Passing in a Galvanizing Line

Producer mills say they can get less than 15 I units of flatness coming off the cold mill. With a temper mill, they can get less than 10 I units. A roller leveler, a Strand Extensioner, or a tension leveler produces less than 5 I units, and maybe less than 1 I unit.
