With replacement of the tandem cold mill in 4-high design, operating since 1963, annual production will be increased by 200,000 t up to 1,300,000 t. The modernization includes the oppor - tunity of later coupling of the tandem cold mill with a new pickling line.

The dependability and the accuracy of the TWS Tensiometer is a requirement in the heavy applications and harsh environment of the rolling mills. Full systems engineering applications are included with all TWS sys-tems. The system consists of high performance strain gage load cells constructed to ...

Reversing Cold Rolling Mill (CRM) Skin Pass Mill (SPM) ... Possibility of configuring combination mill for both cold rolling and skin passing with entry side bridle or bridle on both sides for uniform tension control during skin …...methods. On the entry side of the tandem rolling mill, however, the rolled material is fixed by a bridle roll in the width and traveling directions and cannot rotate on the entry side of the rolling mill. Due to this constraint, a tension distribution, σ′E(x), is formed on the entry side of the rolling mill (Fig. 1(b)).

Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34].This effect has been shown in Fig. 5.14.Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the …...Finally, simulation research is carried out on the speed and tension system of a 1422 mm reversible cold strip rolling mill by using the actual data, and the results show the validity of the ...

Precise strip tension control Two Umlauf Bridle units, one arranged ahead and one after, let's say, a rolling stand or a leveler, can adjust virtually any strip tension required. This capacity makes it possible to enhance the rolling process by adjusting a …...(3) Skinpass mills and tension levelers used for general cold rolling steel plates There are a skinpass mill and a tension leveler installed on the outlet side of a continuous annealing line (CAL), or there is a tension leveler installed on the inlet side of the line with a purpose of improvement of traveling stability in the furnace by

COLD ROLLING MILLS: STRIP TENSION. High consistency in rolling mill operation requires a high accuracy in tension measurement. The BLH Nobel strip tension systems for rolling mills measures the actual resultant strip tension force, as opposed to measuring the indirect force given by the electrical drives current, increasing measuring accuracy and reactivity...Blueprint for excellence. In August 2013, a coupled pickling line and tandem cold-rolling mill (PLTCM) supplied by Primetals Technologies commenced operation at Ternium Mexico S.A. de C.V. (Ternium Mexico) in Monterrey. The facility, which has an annual rolling capacity of 1.5 million tons, is part of a major investment by Ternium to increase ...

Rolling mills are not a standard machine tool, nor are they built for stock. They are designed and built-to-order to specifically accomplish an end product or process. At one point during the industrial revolution in America, the United States led the world in hot and cold rolling, plate mills, slabbing mills and blooming mills...If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x 0.81 = 7096.6, creating 87.6 extra rolling hours. At 114.16 tons/hour that …

tion of rolling, known as strip track-off, is a serious opera-tional problem that can lead to mill crashes and damaged rolls. It predominately occurs at the entry of the tandem cold mill, where the entry tension is relatively low. Operational experience suggests that the strip tracking problem could be reduced if the tension applied to the strip...–Rolling at elevated temperatures to lower the strength of the material –Apply longitudinal tension to the strip during rolling –back tension on the pay-off reel or front tension on the take-up reel • Grind rolls with a camber to prevent crowning of the rolled strip • Radius of maximum camber point generally 0.25 mm

BTU was founded in 1985 by Norbert Umlauf who had developed a technology capable of flexibly building up or reducing the back-tension of strip in strip processing lines while adjusting strip travel in a highly precise manner. That technology helped operators of strip processing lines in cold rolling mills and steel service centers to increase ...In tension control systems, the node for dynamic compensation of disturbance caused by a change in the speed of the rolling stand of cold-rolled sheet mills can contain only one channel that compensates only for the dynamic component. The limitation of the disturbance component due to the inaccuracy in the operation of the indirect torque ...
