Answer: Depending on customer requirement steel can be sold as directly rolled product. When a hot or cold piece of steel is rolled between rollers directly into shapes desired by customer it is called as-rolled condition of quality. In such case rolled product will have grains elongated in direc...

Due to their excellent features, Sundwig S6-high (supported 6-high) rolling mills are mainly used for cold rolling of a wide range of strip hardnesses, widths, and gauges, either in processing lines as high-capacity reduction mills or offline as reversing reduction mills. A special feature of Sundwig S6-high rolling mills are the side-supported ...
Rolling is the most widely used deformation process and for the reason that there are so many versions the process has its own classification. This can be according to the arrangement of the rolls in the mill stand or according to the arrangement of the stands in sequence. Rolling mills are …
Planetary Rolling Mill: In this type of rolling machine, a large backup roller is surrounded by various numbers of planetary working rollers as shown in figure. Each planetary roll gives constant reduction. It is used to reduce large thickness in single pass of steel strip. Its rolling capacity is more than cluster machine but less than tandem ...

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 time of holding [35].
roll-rolling mills appropriate for high precision rolling as the new rolling mill was selected. 2.2 Outline and features of PFB rolling mill As the new rolling mill, two stands of the three-roll rolling mill were selected (Fig. 1). The major feature of the three-roll rolling mill is its ability to suppress the variations of dimension between the
4.Tandem Rolling Mills The Tandem Rolling Mills comprises of a set of two or three strands of roll set in parallel alignment. A continuous pass might be possible through each one with the change in the direction of the material. Many mill rolls manufacturers provide quality tandem rolling mills to various industries. 5.Cluster Rolling Mills
3 High Rolling Mill - Element. 3 High Rolling Mill Rolling mill consisting of three rolls or known as 3 High rolling mill is typically used for performing multiple reduction passes by wrapping material around the center mill roll and performing another reduction on the opposite mill roll pair. 3 High mill can also be used with varying mill roll sizes to induce a specific percentage of ...

Because rolling metal is extremely hard and takes a lot of force, you shouldn't buy a rolling mill without reduction gears. The most common ratios of reduction gears on rolling mills are 6:1, 5:1, and 4:1. A ratio of 6:1 means it takes six spins on the handle for the rolls to complete a single rotation.

In order to analyze the influence of technical parameters on work roll axial force of four-high continuous variable crown (CVC) mill, the deformation analyzing model with top roll system and strip was established based on influence function method. Then a CVC work roll curve designing scheme was proposed and it was carried out on some cold rolling mill considering the requirement of ...
At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods. Many of these products will be the starting material for subsequent manufacturing operations such as forging, sheet metal working, wire drawing, extrusion, and machining.
Either decrease the reduction per pass, together with more frequent interstage annealing, to reduce the rolling force or, preferably, use a four-high rolling mill where small diameter work rolls are backed by larger rolls to prevent the work rolls bending under load, Figure 4.

Planetary Rolling Mills: The Planetary Mill is a medium output mill for rolling of steel strip. Its output is less than continuous mills of many stands but more than the reversing two-high or the three-high mill. This mill can be used to roll all metals but it is especially useful for those which have low ductility.

A two-high rolling mill with 200 mm diameter work rolls was used for the rolling experiment. The test pieces were cut out from portions of the 36%Ni-Fe alloy steel slab so that the rolling direction crossed the columnar crystals shown in Fig. 2. The test pieces were prepared with a shape in which the test piece thickness changed continu-
In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the ...
