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 tw·o-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.


dandy roll is located on top of the forming fabric over the suction boxes. This is a light open structured roll covered with wire cloth, resting lightly upon the surface of the sheet. Its function is to flatten the top surface of the sheet and improve the finish. A pattern on the dandy roll may leave translucent patterns on the wet paper, in the


At today's demanding condition, maintaining stable operation of rolling mill is becoming difficult. MSD is a hydraulic cylinder installed to mill housing window and press a roll chock against the opposite side with constant force. MSD eliminates …


Tandem rolling can be even more advantageous when integrated with continuous casting. The tandem cold rolling process is composed of treading, acceleration, run speed operation, deceleration and tailing out. Figure 3 illustrates a typical speed diagram for tandem cold rolling. It shows the threading is the first phase of the rolling.


Roller mill is a form of compression mill that uses a single, double, or triple cylindrical heavy wheel mounted horizontally and rotated about their long axis either in opposing pairs or against flat plates, to crush or grind various materials.

Two High Non-Reversing Mills: In these mills, two rolls continuously revolve in the same direction and we can't reverse the direction of the rollers. In this operation, the motive power is less costly. 2. Three-High Rolling Mills: In this mill, the three rolls stand in parallel one by others. The rolls are rotating in opposite directions.


finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling 'broadside' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"-diameter work-rolls through 28:1 gears to reduce the slab's thickness by as much as 2-½".

The metal is initially pushed into the space between two rolls, thereafter once the roll takes a ''bite'' into the edge of the material, the material gets pulled in by the friction between the surfaces of the rolls and the material. The …


Rolling is a metal forming process in which the deformation takes place under the application of Compressive forces between the rollers. In this article, we are going to discuss a detailed presentation on the Rolling Process with its Principle, Working, Types of Rolling Mills, Advantages, Disadvantages & Applications.


(i) Two-High Rolling Mill: It Consists of two High stands, and two rolls placed exactly one over the Other. In this type of Rolling Mill, the Rollers rotates in Opposite direction and their direction changes after each Metal pass. The Metal (Ingot) is passed continuously and approximately 25-30 passes are required to convert Ingot to Bloom.

The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.


The web must be "in traction" with all machine idler rolls and driven rolls to ensure proper web handling and control. • The web handling principal states a web will seek to align itself perpendicular to an idler or driven roll. This web handling principal is applied to route webs through processes with parallel idler rolls and driven rolls.

Each stand of the 4-Stand Tandem Mill is driven by two respective four DC motors. The DC drives are supplied via two motor-generator sets, each consisting of a 19.5 MW synchronous motor and four genera-tors. Each generator supplies the armature circuits of two or three main motors. The load is balanced via the field supply. Results


Basic diagram of the fundamental cold rolling process. Cold rolling process. Rolling is an important function of the steel industry. It's a steel fabrication process involving passing the metal through a pair of rollers. There are two main types of rolling process: Flat rolling – the finished product is a sheet


This refers to mixing operations using horizontal two roll mills. The operator (usually known as a mill man) places the various ingredients in the nip formed between the rolls and mixes the compound by cutting it off the rolls and re-feeding it into the nip until all the ingredients are added. Mills are used not only for blending of

Rolling mills are used to perform rolling process. These machines are available in different shapes and size according to requirement of the process and due to technical issues. Every rolling mill consist minimum two rolls. These …


Essentially a size press comprises two revolving rubber covered rolls, pressed together, through which the paper web passes. In the nip formed by the rolls there is a starch solution. The paper absorbs some of this solution, is …


Cluster Mill: The cluster mill consists of two working rolls and four or more backing up rolls. The number of backup or supporting rolls depends upon the amount of support required for the working (small diameter) rolls. Cluster mill is generally used in cold-rolling operation. The arrangement of cluster mill is shown in Fig. 2.9 (d). Type # 5 ...
