mill, where they are rolled to the desired dimensions and coiled. Steel coils may then be further processed in the cold rolling mill to meet customer order specification. The coils may first be cleaned with hydrochloric acid in the pickle line. Cleaned steel can then be reduced in thickness in the cold reversing mill/temper milled.

New Rolling Method of Reversing Cold Rolling. A reversing cold rolling mill has been suffering from such drawbacks as unrolled portions necessarily produced in head and tail ends reduce yield, and time consuming works including removing of coils, threading of the strip and holding of the strip with the tension reel, which result in decreasing productivity.

Figure 15: General Mill Layout (example Reversing Cold Mill) 5.2 Shapemeter Rolls . Usually, during the cold rolling process, the strip is rolled under high tension. This high strip tension compensates for differences in length or shape defects so that the strip appears to be flat during the rolling operation. As soon as the strip is uncoiled

rolling mill can b e designed as 20 Hi, 12Hi, 8 Hi, 6 Hi, 4 Hi and 2 Hi rolling mills. In India now a days mostly 20 Hi and 4 Hi rolling mills are installed in bi g steel produ ction units.

The mathematical model of the cold thin-sheet rolling process on a reversing mill equipped with a four-high stand, a coiler, and a decoiler was constructed based on the data of [6, 7]. Using the equation of the power balance during the reversing rolling, the relation for the specific power consumption ({{W}_{Sigma }}) was written as [ 8, 9 ]

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. It is used to do to get more exact or perfect dimensions and to make the surface quality better. There are such Cold rolled products.

P. Schellingerhout (bottom row, right) global R&D director, Primary Metals, Quaker, Uithoorn, The Netherlands Cold rolling lubrication trials were carried out on a high-speed reversing pilot mill. With low-alloy hot-rolled steel, significant differences were found in friction and strip cleanliness between three different emulsions, comparable to the performance on a production mill.

A four high rolling mill is used for the hot rolling of armor and other plates as well as cold rolling of plates, sheets and strips. 4: Tandem rolling mills: ... In two high reversing rolling mills the rolls rotate ist in one direction and then in the other, so that rolled metal may pass back and forth through the rolls several times. ...

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 passing of thinner gauges.

The reversing cold rolling mill is used mainly for producing coils of ordinary carbon steel in emerging countries, and is used for producing small lots of a variety of coils of high-grade steel or special steel in advanced countries.

Roughing/Reversing Mill Application Overview At the reversing mill, rolling speed, roll bite and coolant flow may be optimized only with a precise real-time knowledge of metal temperature. The low and highly variable non-greybody emissivity character associated with this complex aluminum process dictates the

repeatedly passed back and forth through the mill. Reversing mills are usually used for smaller scale production of the specialty cold-rolled products. For high mass production we use tandem-type rolling mills, whereby the strip undergoes a single pass through a train of rolling stands before being wound into coil form.

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.

thickness and hardness after each pass through the rolling mill. Tighten the rolls only a small amount at each step or a safety pin will break. 3. Plot a curve of hardness vs. percent reduction in thickness. On the cold-rolled sample (flattened, slightly warped piece of brass), perform the following: 1. Measure the hardness using Rockwell B ...

Steel rolled in two-stand reversing cold mills is suitable for a wide range of applications, offering the best possible performance in terms of quality and productivity. A two-stand reversing cold mill can deliver capacities between 300,000 t/a of thin-gauge products or 1,000,000 t/a and more of thicker-gauge products.
