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.
2. Outline of Reversing Cold Rolling Mill (1) Outline of reversing cold rolling mill and rolling method As illustrated in Figure 1, a reversing cold rolling mill is comprised mainly of a mill proper, a winding machine (pay-off reel), an entry winding machine (entry tension reel) and delivery winding machine (delivery tension reel).

In the industrial practice—especially in the reverse rolling mills—heavy section products with stable mechanical properties (YS, UTS) and ductility (A, Z) but with an impact toughness (KV) at too low levels are often observed. The results presented in the present work concern the relationship between the parameters of the cooling process of rolled products made of microalloyed steels, with ...
2: Three high rolling mill: It consists of a roll stand with three parallel rolls one above the other. Adjacent rolls rotates in opposite direction. So that the material may be passed between the top and the middle roll in one direction and the bottom and middle rolls in opposite one. In three high rolling mills the work piece is rolled on both ...

What makes single-stand reversing mills stand out is their very broad product spectrum. They are the best option for efficient rolling of silicon steel and special grades. That's because you can freely determine the number of passes and the rolling speed to suit the material.
In such roughing mills, the thickness of the plate is reduced in several (reversing) passes. The width of the plates increases due to spreading and can be reduced by the edger rolls. If the edger rolls are located upstream (downstream) of the mill stand, they may be used in …
Rolling mills. Rolling mill consists of rolls, bearings, structure, or housing for rigidly supporting these parts, power drive, power transmission system, speed control, roll gap adjusting set up, etc. The force for rolling generally is very high. The power requirements are …

What Does Reversing Mill Mean? A reversing mill is a rolling mill in which the workpiece is passed forward and backward through a pair of rolls. The reversing mill is so named because the steel runs back and forth between the rollers, reducing the thickness incrementally with each pass. A reversing mill can be used to reduce material to gauge.

2 Principles and Applications of Metal Rolling (ii) Shape of the rolled product- flat, sections or hollow sections rolling. (iii) Direction of rolling- lengthwise, transverse, and skew rolling. (iv) Mode of rolling mill operation- continuous (unidirectional), and reverse rolling, where direction of rotation of rolls are reversed. When two rolls of equal diameter and with axis lying in same ...
Notes on Purchasing Rolling Mills ***When you purchase a rolling mill, be sure to consider how wide the flat rollers are: you don't want a rolling mill that can only roll out narrow strips of metal (or maybe you do!). Determine what your needs are and buy accordingly. Mills come in varying designs. Some include wire grooves, pattern rollers and flat rollers.
2 High Rolling Mill - Element. 2 High Rolling Mill. Rolling mills consisting of two rolls or known as a 2 High rolling mill is used for anything from temper pass to breakdown of material. The 2 High rolling mill typically have larger diameter work rolls that are positioned with actuators that either have: Hydraulic. Pneumatic. Electro-mechanical.

Salient Features of JSW Cold Rolling Mills. Widest Cold Rolling Mill for automotive steel in India. First Continuous Annealing Line India. State-of-the-art continuous galvanizing line with dual pot system for GI & GA production. Higher Strength (up to TS 980MPa) & SEDDQ grade, which cannot be produced by current Indian facilities.
The reversing cold rolling mill is the all-rounder among the cold rolling mills: Here, thin strips, thick strips, soft grades, high-strength and ultra-high-strength strips can be rolled in succession on one and the same plant. The RCM is mainly used for low carbon steels, but is also a good solution for modern grades such as silicon steels.
The setup function for roughing mills minimizes the number of passes of reverse rolling and maximizes the rolling productivity considering the machanical and electrical capability of the mill. The width setup model reduces width deviation.
