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).
Two-high rolling mill: consists of two opposing rolls. These rolls may rotate only in one direction (no reversing) or in two directions (reversing). 2. Three-high rolling mill: allows a series of reductions without the need to change the rotational direction of the rolls.

3B(2) Deformation of Rolling Mill jfe21stcf.or.jp. The ratio of the rolling force to the amount of vertical deformation of the whole rolling mill, including the deformation of the roll, screwdown device, and housing, is called the mill modulus. The mill modulus is 5001,000 ton/mm for plate rolling mills and 400600 ton/mm for cold rolling mills.

This paper presents a completely new approach to the mechanics of the Sendzimir hot planetary rolling mill. Previous work on this subject, by R. Tovini, included determinations for the distribution of the advance of the strip, the draft, the rolling load, the torque and the horizontal backthrust for the whole range of positions which the planetary rolls made, whilst contacting the hot metal.
Understanding Rolling Process in Long Product Rolling Mill . Steel rolling consists of passing the material, usually termed as rolling stock, between two rolls driven at the same peripheral speed in opposite directions (i.e. one clockwise and the second anti-clockwise) and so spaced that the distance between them is somewhat less than the ...
