The stretch leveling cut-to-length line, dubbed, "The Memeory Eraser" recently underwent some exciting upgrades. As a result, the four year old Butech Bliss cut-to-length, originally rated to process .750" x 74" x 70,000 lb. hot-rolled, cold-rolled and coated carbon steels, is now processing 1" in. thick material flawlessly.
The looper control of hot strip finishing mill is one of the most critical control items in hot strip rolling mill process. It is a highly complex nonlinear system, with strong states coupling and uncertainty that present a difficult control challenge. Loopers are placed between finishing mill stands not only to control the mass flow of the two stands but also …

In a typical rolling mill that produces sheet steel at 250 um, the noise at a 10 ms mean response time might be on the order of +/-0.10% (2 sigma). With the improved signal …
Cut-to-Length lines, often called CTL lines, are pivotal machines in the metal processing industry. They convert coil rolls into precise lengths of sheet metal blanks, encompassing several stages, including uncoiling, straightening, shearing, and stacking. The CTL line begins with a master coil sourced from an integrated or mini mill.
A COLD-ROLLED strip is a steel product produced from a pickled hot-rolled sheet. Cold rolling is the mechanical working of steel below the recrystallization temperature [1], which improves the ...

This process is commonly used for shaping large sections of metal quickly and efficiently. In contrast, cold rolling occurs at or near room temperature, imparting greater control over the dimensional accuracy and surface finish of the metal. Cold rolling is often employed for producing thin sheets or precision components.

Some processors compromise with a five-high leveler. The adjustable backup flights for cold-rolled coils usually are on the bottom work roll bank. The intermediate rolls on the bottom are eliminated, and the full-length intermediate rolls on the top are retained. This means we won't stripe the top surface of the coil, but we may …
The cold rolling mill is used to pass hot-rolled coils produced from the hot rolling mill between two rotating rolls and produce products of the desired thickness. The cold rolling process provides a more refined surface, improved mechanical properties and excellent thickness product precision. Cold rolling mills are largely divided into the ...

the hot rolling mill is coiled for transport to the cold mill which might be on the same site or elsewhere. Cold mills, in a wide range of types and sizes are available; some are single stand, others 3 stand and some 5 stand (Figures 1301.02.03 and 1301.02.04). Cold rolling speeds vary but modern mills operate at exit speeds as high as 3000 m per
Video Source - Bascotecnia Steel - Rolling Mills. Specifications and Applications. When choosing rolling mills, roll diameter and the type of metal to roll are important specifications to consider. For each series, model, and type of machine, three diameters may be listed: work rolls, back-up rolls, and roll journal.
After surface conditioning, the bands are usually cold rolled directly to final gage, and sold to the transformer manufacturer in one of two conditions fully-processed, or semi processed. After final cold rolling, the strip is annealed, decarburizing it to 0.005% C or lower and developing the grain structure needed for the magnetic properties.

Taking the 2130 cold rolling production line of a steel mill as the research object, feature dimensionality reduction and decoupling processing were realized by fusing random forest and factor analysis, which reduced the generation of weak decision trees while ensured its diversity. The base learner used a weighted voting mechanism to …
The mill setup system consists of model-based actuator preset calculation systems for both thickness and flatness. Adaptation of the roll force and strip shape models is provided by means of short- and long-term parameter recalculation loops. The mill setup system includes the following functions and features:
