Sendzimir Rolls aka Cluster mill rolls, diameter ranges from 20mm to 340mm, maximum length of which can reach up to 2800mm The categories of sendzimir rolls are composed of following: Work roll 1st Intermediate Roll 2nd Intermediate Roll For Work Roll, we suggest following material: MATERIAL : M1 (AISI M1, DIN13346) 1 Chemical The development of roll material is representative of the development of cold roll technology At present, there are four main series of cold rolling rolls commonly used in China, such as 2% Cr, 3% Cr, 5% Cr and SHSS (semihigh speed steel)Development and application of cold roll Taixi Mill Compared with the hot roll, the cold roll only rolls the coldrolled piece, which is usually cast after smelting and often needs to be forged With the development of casting technology, the cold roll is forged It is being implemented continuously The cold roll has a cold rolling work roll, an intermediate roll, and a support roll, the work roll What is a Cold Roll?

GENERAL ASPECTS OF ROLL COOLING FOR HOT COLD
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 drive the work rolls through the couplings and roll necks is limited by their diameters, which in turn are Table 1 Concept of choice of work roll diameter in cold rolling Transactions Is", Vol 23, 1983 (23) limited by the distance between their installed centers, in a tandem cold mill, the strip tension is sometimesSelection of Work Roll Diameter for Cold Rolling Mill* The rolls used in Rolling Mill included different material and size, such as high alloy forged rolls, muticasted iron rolls etc The sizes are fromΦ360 mm toΦ1960mm, hardness layer in difference depth by heattreatment New rolls and used rolls are inspected by different NDT methods to make sure its in good condition for next rolling turnUsing NDT Methods for Inspection Rolls of Cold Roll Mill Fig 2, Heat Migration in Cold Mill Work rolls (Hotter regions shown in red) This localized heat input / output process results in a nonuniform distribution of heat, circumferentially around the roll and transversely across the roll body Additionally the roll is subjected to Thermal and Fundamentals of Roll Cooling and Control of Flatness at Typically, the number of backup roll cycles is as shown in Table I TABLE 1 TYPICAL BACKUP ROLL CYCLES FOR DIFFERENT MILL TYPES MILL TYPE srAND PRODUCT NUMBER OF THICKNESS BACKUP ROLL (mm) CYCLES/PRODUCT Tandem cold mill First 03 100400 Tandem hot mill First 25 1025 Last 25 50200 Plate mill Last 100 16 A review of previously proposed Roll Eccentricity Control for Strip Rolling Mills

Fundamentals of Rolling ScienceDirect
Other chapters consider the range of application of various types of rolls and show the basic dimensions of a roll This book discusses as well the different types of rolls for various rolling mills, including blooming, plate, sheet, sheet bar, small section, heavy product, skin passing, and cold rolling mills This affects the roll life and increases the roll cost per ton It is a fact that all mill rolls eventually deteriorate and the roll passes need to be changed to achieve size control and finished PROCESS OF ROLLING MILLSThe second paper proposes electroless nickel dispersion coatings with a broader field of application, not limited to cold mill work rolls but also to boost wear resistance on hot mill rolls New developments in roll surface texturing will be discussed in the third paper The final paper in this session, from a broad consortium comprising IOM3 Roll surface treatments assessments Fig 2, Heat Migration in Cold Mill Work rolls (Hotter regions shown in red) This localized heat input / output process results in a nonuniform distribution of heat, circumferentially around the roll and transversely across the roll body Additionally the roll is subjected to Thermal and Fundamentals of Roll Cooling and Control of Flatness at Xtek’s Roll Reconditioning and Repair Services extend into the specialty roll area as well Periodic or routine maintenance programs on Hot Strip Mill Edger Rolls and Downcoiler Pinch Rolls are a part of the services conducted Xtek These programs often include the machining of a passline profile or the regrinding of the body diametersRoll Repair Xtek, Inc
