Shape (or flatness) control for rolled steel strip is becoming increasingly important as customer requirements become more stringent. Automatic shape control is now more or less mandatory on all new four-high cold mills, but no comprehensive scheme yet exists on a Sendzimir mill. This is due to the complexity of the control system design on such a mill, where many more degrees of freedom for ...

In many cases, the product becomes slightly trapezoidal in shape instead of the perfect square. Cold Rolled Product: Cold rolled product is made from the hot-rolled product. When the hot-rolled product is cooled, then that is re-rolled in the room temperature. It is known as Cold Rolled Product.

Roll Contour Optimization for Cold Temper Mill Jiang Zhenglian (Cold Rolling Plant of Baosteel Branch, Shanghai 200941, China) Abstract: A study on the performance of strip shape control has been carried out for a 2000 mm single stand cold temper mill. The theoretical model for roll contour optimization was set up, with roll elastic deformation ...

This ensures that shape can be closely monitored through the entire pass schedule in both directions and results in excellent shape control. COLD REVERSING TEMPER MILL (CRTM) The CRTM is identical to the CRM in every respect except that it can temper roll as well as cold roll.

Currently, work roll shifting mill is the most effective mill for strip shape control [12, 13] because it improves the strip crown accuracy and edge phenomenon, as well as permitting schedule free rolling [14, 15] by changing the gap equivalent profile in the roll bite [10, 16].

mechanics. With the need for higher quality and productivity in cold strip mill, mathematical models of cold rolling of a strip with a desired shape and dimension, both for mill set-up and for on-line control, have become a key issue in the steel rolling process. One major part of these models concerns the strip and roll deformation ...

We claim 1. A method of controlling the shape of a rolled strip delivered from a rolling mill which contains a work roll and means to vary roll force created by said work roll, comprising: rolling a strip to final gauge while subjecting said strip to from about 0.25 percent to about 6 percent elongation in length while using a work roll size and a roll force within a range that, for said roll ...

Reducing our hot rolled coils through our continuous pickle line and in-line tandem cold mill (PLTCM) produces cold rolled steels ranging in thickness from .012" – .100" and 36" – 72" in width. Our investment in technology allows us to meet the tight tolerances and surface finishes customers demand in fully processed cold rolled steels.

With new automatic gauge control (AGC) technology, the mills are doing much better, but perfection remains an elusive goal. At the Cold Mill. At the cold mill, every time we change the thickness profile, we also change the flatness. The cold mill roll gap should start out being set to the same profile as the crown of the incoming hot mill product.
