A four high rolling mill is used for reducing material to minute thicknesses. Through the use of backup rolls, the issues of roll deflection can be avoided and smaller work rolls can be used. The reduction in work roll diameter reduces overall separating force required for reductions; reduces the overall energy needed for reducing the material and produces more consistent thickness output.
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 reduction of material on a single side of the work piece.
Terms Used In Three High Roll Mill. This process consists of three reheating furnaces, a sizing press that reduces the slab width, three roughing mills, a coil box, a joining device sheet bar welder, a 7stand finishing mill, a strip shear and two down coilers. The layout of the endless rolling process is being illustrated in the figure below.
Typical roll speeds would be 1,300 feet per minute (~ 395 m/min) for a 9inch (~23 cm) roll to 3,140 feet per minute (~957 m/min) for a 12inch (~ cm) roll. Usually a single motor is used to power a two high roll pair, with either belt or chain reduction supplying the differential.
Three roll mills or multishaft mixers with high speed dispersing blades are used to disperse solids into low viscosity components. The high shearing action helps break up solid agglomerates and ensure that the fillers are completely we out and uniformly distributed in the resin.
This is becoming common whether a 2high, 4high, 6high, or cluster mill. Before dual motor drives, rolls had to be ground the same diameter. If one roll needs to be ground, the opposing roll must be ground at the same diameter. Fourhigh mills are very common for steel, aluminum, copper, and any high production metal rolling.
#0183;#32; High Rolling Mills The Three High Rolling Mills comprises of a roll stand with three parallel rolls one above another. The adjacent rolls rotate in the opposite direction to pass the material between the top and middle roll in single direction, and the bottom and central roll in the opposite direction.
The rolls of a three high rolling mills may be either plain or grooved to produce plate or sections respectively. 3: Four high rolling mill: It has a roll stand with four parallel rolls one above the other.
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:
A fourhigh mill has four rolls, two small and two large. A cluster mill has more than 4 rolls, usually in three tiers. These types of mills are commonly used to hot roll wide plates, most cold rolling applications, and to roll foils. Historically mills were classified by the product produced:
Products gt; Three Roll Mills gt; Three Roll Mill How the Three Roll Mill Works. The material to be milled is placed between the feed and center rolls. Each adjacent roll rotates at progressively higher speeds. For example; the feed roll may rotate at 30 rpm, the center roll at 90 rpm and the apron roll at 270 rpm.
Indian Integrated Steel Plants normally use high ash coke produced (normally at Room Temperature) to produce cold rolled sheets /strips /coils. Mills used for the purpose are called Cold Rolling Mills. 2Hi/4 Hi/6 Hi/20 a 2 Hi mill consist of 2 rolls one above the other known as Upper roll and the Lower roll. In a 4 Hi mill
2. ThreeHigh Rolling Mills: In this mill, the three rolls stand in parallel one by others. The rolls are rotating in opposite directions. In this mill, between the first and the second rolls, the material passes. If the second roll rotates in a direction then the bottom roll rotates in another direction.
Rolling mills often vary in the type, number, and position of rolls. Rolling mill arrangements commonly used in manufacturing industry today include the two high mill, the two high reversing mill, the three high mill, the four high mill, the cluster mill, and the tandem rolling mill.

A three roll mill or triple roll mill is a machine that uses shear force created by three horizontally positioned rolls rotating in opposite directions and different speeds relative to each other, in order to mix, refine, disperse, or homogenize viscous materials fed into it.. The threeroll mill has proven to be the most successful of the range of roll mills which saw extensive development in
Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. Under rolling conditions the contact area between roll and stock suffers wear, the other parts of a roll body and necks have to be considered as normal parts of designed components under high
