Except for the cold rolling mills complex installed under Bokaro, million tonne expansion and the reversing cold mill of Nippon Denro Ispat. Ltd. and a few others, all the existing plate mills, hot rolling mills and cold rolling mills in the country need to be modernised to meet present day production and quality requirements. Large scale mod
However, roll shifting is difficult for a fully tandem cold rolling mill when the welded coils are rolled continuously and the roll shifting is conducted under the condition of a large rolling load [10], [11]. Due to the existence of a rolling load and friction in the contact zones among work roll, backup roll and strip, the thrust force occurs.

Strip cold rolling is a technology for metal sheet and strip rolling below recrystallization temperature. The raw material is usually hotrolled steel strip or plate which is rolled by a cold rolling mill at normal temperature to produce steel profiles. Coldrolled strip steel and steel sheet have advantages, such as smooth surface, high ...
What is claimed is: 1. A method for controlling edge drop of a steel strip rolled through a tandem cold rolling mill including a first group of rolling stands and a second group of rolling stands, said first group of rolling stands having one or more rolling stands arranged in series with an inlet side and and outlet side and including at least a first stand, each said rolling stand of said ...

For instance, the ESP has demonstrated that mill threading can be suppressed, allowing the production of hotrolled coils in thinner gauges, down to mm hotrolled (HR) strip products. These, in turn, can be used to form coldrolled (CR) strips down to 200 microns, or mm, suitable for electrical grades of steel, for instance.
A computer simulation program that can analyze the dynamic behaviors of tandem cold rolling process without laborious experiments in actual mill was developed. By using this simulation program, the stability and accuracy of strip thickness control system were evaluated for various disturbance such as hot band gage, roll eccentricity, and deformation resistance of hot rolled strip. Herein the ...
Anisotropy in texture determines capacity of the steel to achieve maximum plastic flow in the plane of the sheet and maximum resistance to flow in a direction perpendicular to the sheet. Present work has been carried out to explore the potential of maximizing plastic anisotropy (rm) value in extra deepdrawing steel. Industrial heat was made with low carbon ( wt.%), low manganese ( wt ...
1. Introduction. Flat cold tandem mills (see [1]) have the purpose of reducing the thickness of flat steel by means of consecutive rolling passes, through 35 housings called rolling stands. This type of process is widely exploited in order to feed a wide variety of industries from food industry to automotive industry.

When two rolls of equal diameter and with axis lying in same ...
The tandem cold rolling process is composed of treading, acceleration, run speed operation, deceleration and tailing out. Figure 3 illustrates a typical speed diagram for tandem cold rolling. It shows the threading is the first phase of the rolling. Following the threading, dynamic control loops (AGC and AFC) are closed and corresponding ...
Cold rolling mills also operate at considerably higher rolling speeds of sometimes above 2,000 m/min, and entry and exit tensions are applied to the strip to assist the deformation. In the cold rolling operation, the high specific loads lead to considerable roll flattening and bending. With smaller reductions and thinner strip, the elastic ...

In simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. Cold rolling, unlike hot rolling such as with hot rolled steel, can only occur when a metal is below its recrystallization temperature. Where hot rolling is performed using high temperatures, cold rolling is performed at room temperature.
We work closely together with customers to improve their cold rolling process with customized oil compositions. These efforts initially lead to an improved surface quality and reduced energy consumption of the mill engines as optimized lubrication reduces the friction. Even more significant is the increased productivity achieved at various customers around the globe by reducing the amount of ...
The United States accounted for percent of world pig iron production and percent of raw steel during 2006.
