Thanks to its broad range of cold rolling mills for strip widths from 60 to 2,100 mm, ANDRITZ Metals has been one of the preferred cold rolling technology suppliers for decades. The supply focuses on 2-high rolling mills, high-capacity 4-high reduction rolling mills, and inline skin pass mill stands.
A Z-Mill or Sendzimir Mill is a machine for rolling steel. Unlike a traditional rolling mill this 20-high cluster mill configuration utilizes cascaded supporting rolls to apply force on the small work rolls in the center. This allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality.
The three high rolling mill utilizes the principle of passing the work back and forth to achieve a series of reductions. Unlike the two high reversing mill, the three high mill has three rolls that always spin in the same direction. An elevator mechanism lifts and lowers the work so that it can be passed back and forth through the rolls.
Start studying Chapter 19 Manufacturing. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Search. ... A two-high rolling mill consists of two opposing rolls between which the work is ... the maximum reduction possible in a wire drawing operation, under the assumptions
Rolling mill consisting of four rolls or known as a 4 High rolling mill is used for reducing material to extremely small thicknesses. Through the use of larger backup rolls, the issues of roll deflection can be avoided and smaller work rolls can be used. This reduction in work roll diameter: Reduces overall separating force required for reductions
10 Tips on How to Use a Rolling Mill. Richard outlines how to use a rolling mill, and 10 ways a mill can be useful in your studio to help you be more creative. Here's how to use a rolling mill and some helpful tips: 1. Rolling mills can be used to roll a metal sheet into a thinner sheet, which will also work-harden it.
The plant comprises of bloom rolling mill, billet rolling mill, and rail and structure rolling mill and heating furnaces. Bloom rolling mill is generally a single stand mill which is a two high reversing stand having roll diameter in the range of 1150 mm to 1600 mm and roll length of 2800 to 3000 mm.
That are usually employed for initial rolling of an ingot. Three high rolling mills or triple roll: triple roll or three rolling mill. The three high rolling having three rolls rotate in only one direction, the work metal is fed between two rolls and then return through the another pair.
Nov 25, 2016· Two-high rolling mills have a unique advantage in cost saving because a 2-high configuration is less expensive to manufacture. A 2-high mill can be any size. Large rolling mills are used for skin passing with small reductions of 1% to 2%. Since the material is not always uniform across the width, a 2-high rolling mill can be equipped with roll bend.
Nov 28, 2016· A 4-high rolling mill can be a small mill or a stand-alone, high torque, high reduction mill. A typical reversing mill has a quick change roll system. Four-high mills can be equipped with roll bend and shape control, a precision consistent product. Old 4-high cold rolling mills can be upgraded.
Used Rolling Mills. Rolling mills are mainly used in the sheet metal processing industry and in the jewelry processing. Various materials can be used like steel strips, steel sheets, copper, gold, titanium, as well as wire or tubes and profiles. There are two-high or DUO-rolling mills, four-high or QUARTO-rolling mills and reversible rolling mills.
Characteristics of Rolling Mill. The frame with integral casting has high rigidity and the rolling force acts radially on each section of the frame. 2. The work roll has a small diameter and the pass reduction rate is high, up to 60%. Some materials can be rolled into very thin strips without intermediate annealing. 3.
rolling mill process in order to maximize throughput and minimize cost and crop losses. He applied computational Intelligence based optimization for the first time to the rolling schedule of tandem cold rolling mill. Rolling schedule is a set of multiple rolling parameters such as reduction, roll force, torque, rolling speed and tension.
Chatter problems on a cold rolling mill. One of our customers was experiencing periodic surface markings on products from their cold rolling mill. Consequently, they were unable to supply high surface quality material from this particular mill. Therefore, they asked our aluminium rolling experts to get to the bottom of the problem. Chatter marks

Rolling mills have many functions. They can be used to reduce the thickness of material quite accurately (+/-.0001") or compress the material to create a uniform density throughout the strip or
Tags Rolling, Rolling Mills; 3-High Rolling Mill. Three-high rolling mills consist of a large back up roll, small work roll, and another large back up roll. The purpose is to have a very minimum amount of reduction. Three-high mills are commonly used for making bearing material for gasoline and diesel engines (see cladding).

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.
In this chapter, a 2-high micro rolling mill has been built successfully, and experimental investigations on the micro rolling process for ultrathin strip have been conducted. The rolling reduction limit is analyzed considering roll material, rolling pass, and rolling speed ratio between two rolls. The rolled material profile evolution has also ...
A tandem mill is a special type of modern rolling mill where rolling is done in one pass. In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18.
Rolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section ... (high R) and rough treads (high, μ.) on farm tractors and off-road earthmoving equipment, thus permitting the vehicles to travel ... the cross section in each reduction. Fig. 5.5 5.5 rolling mills:
May 30, 2013· Slit rolling for bar production. In merchant bar mills with conventional rolling, rounds and rebars (both of them commonly known as bars) are produced from billets which are rolled in a sequence of passes through a multi stand rolling mill.
