Hi Mill Cold Roll Flow Chart

The rolls can be ground to an hourglass shape. A 6-high mill also allows for substantial roll shape, depending upon the horizontal movement of the rolls. Another advantage of a 6-high mill is a larger work roll which can transmit considerable torque and allow for high speeds up to 7,000 FPM. Large diameter, light gauge coils can have thousands ...4 HI MILLS 02 4-HI REVERSING COLD MILLS Magadh can offer 4 Hi reversing cold mills for strip width up to 1650 mm, minimum finish strip thickness up to 0.15 mm and mill speeds up to 1400 MPM. The main mill features are : Balanced proportional design of Mill Stand. Quick response Hydraulic AGC System. High (+/-) work roll bending force per neck.

This 1450mm 20 Hi Reversible Cold Rolling Mill was designed to roll 1.0~3.0mm plain carbon steel, low alloy steel and 200, 300,400 series stainless steel board into 0.2-1.2mm thick as clients'requirement.

The 3Hi Cold Rolling Mill is used mainly for breakdown rolling of thick sheets/ plates of metals like Copper, Brass and Aluminum where the weight of sheet is on the higher side. It is difficult to return such heavy sheets back to the operator after the pass so the 3Hi Mill is advantageous in such scenario because it provides for reversible ...Tenova I2S is a recognized leader in technologies and innovative design and supply of cold rolling mills. Since 1974, Tenova I2S has specialized in providing customers the highest quality solutions in a broad range of mill types for production of stainless steel, carbon steel, specialty steels and non-ferrous metals.

Product description. 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 wide range of strip widths...ControlIT for Cold Rolling Mills Technological control for cold rolling processes Rolling of flat metal products is a complex proc- ... strip section reaches the roll gap. Mass flow control Using the mass flow principle, the outgoing strip thickness at the …

6-Hi Reversing Cold Reduction Mill. Gives the work rolls adequate support at strip edges through the action of the intermediate roll on the back- up roll so that strip shape can be preselected. Improves roll force distribution over the strip width and, installation and positioning of the intermediate rolls enhance the effectively of work roll...A two-stand reversing cold mill can deliver capacities between 300,000 t/a of thin-gauge products or 1,000,000 t/a and more of thicker-gauge products. Main benefits of Primetals Technologies' reversing cold mills. High production capacity and yield; Flexible, low-cost rolling of a wide range of products, especially for small order lots

Cold Rolling Mill, Zoom-MillTM, Off-gauge, Minimization, Yield, Productivity, Labor saving, Leader strip, Spot welder, Even-numbered Pass 1. Introduction For the production of cold rolling steel strips in a yearly production capacity range from 150,000 to 300,000 tons, a reversing cold rolling mill, which...Sendzimir Mill Features . The Sendzimir mill arch is integrally cast and pre-stressed, and a circular arc track is provided in the arch to secure the backup roll. All the intermediate rolls are fixed on the arch by the suspension hydraulic cylinders on the transmission side and the operation side, and the suspension force is set according to the weight of the roller body.

The 20 high rolling mill from ANDRITZ Sundwig is mainly used for cold rolling of metal strip to thinnest final gages and wide range of strip width. The special feature in a 20 high mill is the relation between work roll diameter and barrel length...Mechanics of Cold Rolling of Thin Strip 443 where yiw is the vertical deflection of the work roll at element i, gijw (, ) is the influence function for the work roll deflection due to the combined bending and shear forces generated by rolling load, giwf is the influence function for the work roll deflection due to the force generated by the roll bending mechanism, k represents the …

Production flow chart 2. What Can be Detected? Defects stem from a variety of causes such as poor billet quality, worn rolling mill parts, and process malfunctions. Detectable defect types are many and include shells, cracks, pinholes, scabs, inclusions, laps and overlaps (Figure 2), as well as repetitive defects ECNDT 2006 - We.1.8.3 1...His successive functions were: mill operator. (20 Hi, skin pass), technician in design office for mills, finishing operations, annealing and pickling. In 1986 he founded the company SARL DUPREZ, the activity is trade and services. He manages this company. and works in freelance as cold rolling expert. 2- The missions assumed around the world.

2 High Rolling Mill - Element. 2 High Rolling Mill. 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 …...KT Mill (Kobe Twelve-high Mill) is a high-performance rolling mill having the respective features of our 4-high and 20-high mills, which have excellent strip flatness functions, and corresponds to the demand of improved strip flatness. …

In order to solve the problem of flatness defects and roll spalling caused by rolling thin gauge strip in the 1 500 mm UCM (6-high middle rolls …...Thus, it was desired to develop a new type of mill which is capable of controlling the rolled strip shape even with changes in rolling conditions. The performance of a conventional 4-High mill is not satisfactory in these requirements. A new 6-High cold rolling mill (hereinafter HC-MILL) has been developed in order to solve these shape problems.

trolling the roll gap position is such that produces the desired output thickness [6]. Roll eccentricities are caused by axial deviations between the roll barrel and the roll necks due to irregularities in the mill rolls and/or roll bearings [11]. These irregularities cause cyclic deviations in the strip thickness at the output of a mill stand...PROCESS FLOW CHART. The basic raw material is medium carbon & high carbon hot rolled coils. The coils are slitted on slitting machine for obtaining the required width of hot rolled strips. After slitting these hot rolled strips are acidly …
