The diameter of the 6-high work rolls amounts to approximately 1:4 in relation to the barrel length. In comparison to a 4-high mill stand, the utilization range is wider. This type of rolling mill is mainly used in offline applications for cold rolling of soft and medium strip and for a …
The work rolls used in cold rolling mills are expected to perform under very arduous operating conditions. With the advent of faster mills and the increase in load, the quality of rolls needs continuous improvement. Cold mill rolls should withstand mechanical and thermal shock, must have excellent wear resistance and very little plastic ...
The most common configuration is the single reversing mill. Various mill designs are offered that include 6-high UCMs (Universal Crown Control Mill), ZR mills and 12-high cold-rolling mills with small-diameter work rolls for the efficient rolling of materials of high hardness.
These backup rolls are larger and contact the back side of the smaller rolls. A four-high 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. [9]
In general in tandem cold rolling mill / two-stand cold reversing mill the stands can be of 4- high type or 6-high type (i.e., stands with 6 rolls). The single stand cold reversing mill process can be achieved (in particular for stainless steel) with stands of 20-high type also known as cluster mill or Sendzimir mill.

The potential of PVD coatings, TiN, CrN and TiBN, as coatings for mill rolls in stainless steel strip cold rolling has been analyzed, by evaluating the tribological properties and contact fatigue resistance; both types of properties are essential for productivity. These coatings were compared to uncoated steel currently used in this industry.
Rolled Metal Characteristics • Residual stresses • Dimensional tolerances for cold-rolled sheet thicknesses +/- 0.1 mm to 0.35 mm (0.004 to 0.014 inch) • Flatness tolerances to within +/- 15 mm/m (3/16 inch/foot) for cold rolling, +/- 55 mm/m (5/8 inch/foot) for hot rolling • Hot rolling and sand casting produce similar ranges for

rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.
Mill Roll is the main working component and tool of the rolling mill, and the use is to make the metal continuously plastic deformation. The mill roll is mainly composed of a roll body, a roll neck, and a shaft head, three parts. The mill roll can be arranged in two rolls, three rolls, four rolls, or multi-rolls in the housing.
PRIMARY COLD REDUCTION (DARON LLOYD MANAGING DIRECTOR, LECHLER LTD) PREAMBLE In the process of Rolling the most significant aspect is the generation of heat through friction and deformation in the roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip
Driven by the technology of pulling and roll manufacturing in the cold rolling industry, the requirements for increasing the wear resistance, roughness retention, hardness uniformity and anti-accident of cold rolls are increasing, with the aim of achieving free rolling., rolling high-grade plates, reducing roll consumption and so on.

Hot and cold metalworking between two or more rolls has been in existence since long before the industrial revolution. As a matter of fact, Leonardo da Vinci was credited for the metalworking mill prior to his death in 1519. When most people think of a rolling mill, they visualize sizable machinery in ferrous (iron, carbon steel
Sources of chatter in rolling mill Table 1: Chatters reasons. S.No Reasons of Chatters 1 Due to problems in drive systems: Misalignment of gears (Excitation proportional to speed)Tooth engagement, Gear defects 2 Roll ripples/ Unbalance or eccentricity of rolls/ Speed of rolls 3 Periodic grinding of rolls 4 Friction conditions lead to excitation
These outstanding cold rolling mill rolls are equipped with water cooling modes, tensile tester, impact testing machine, metallography analyzer, and many more features. These cold rolling mill rolls are also equipped with effectively filter laser radiation, are eco-friendly, and reduce the damage to the machine operators.
The team conducted a survey of mill elements known to contribute to chatter. They looked for defects in the work roll bearings inner races that were likely to create similar markings to the ones experienced in the cold rolling mill, as shown in figure 3.
