Cold rolling mill 6-high - Andritz

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.1. Two High Rolling Mills It contains two heavy rolls fixed one over the other. The rolls are supported in bearing housed in sturdy upright frames (called stands) which are grouted to the rolling mill floor. The vertical gap between the roll is adjustable. The rolls rotate in opposite directions and are driven by electrical motors.Rolling Mills: 6 Different Types of Rolling Mills [Images & PDF]Four-High: A 4-HI mill may be used for finish rolling of thin gauge stock. 6-HI roll inserts are also available for narrow width ribbon and foil products. Combination: A combination rolling mill is a versatile “two-in-one” type of metal rolling mill that permits both 2-HI and 4-HI rolling operations.Different Types of Rolling Mills & What They Do - Fenn Torinاحصل على السعر

03 Types of Rolling Mills Rolling mills compress metal into a uniform thickness, bend it into custom shapes, and create custom-sized stripping. There are many different types of rolling mills, and the optimal mill for your product depends on the metal and rolling process your manufacturer will use.PROVIDING USED & BUILT TO ORDER METAL MACHINERY! 4-High Rolling Mills Four-high rolling mills can be put in tandem, two to seven stands, instead of a reversing mill. They can be equipped with load cells to tell the separating force and hydraulic or mechanical screw downs, depending if it is hot or cold rolling.4-High Rolling Mills | Metal Processing Machinery - American SteelThe 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. The HC-MILL for steel rolling was put into a practical operation at Nippon Steel Corporation at Yahata Works (now, Nippon Steel & Sumitomo Metal ...6-High Type Rolling Mill for Cold Rolling | SpringerLinkاحصل على السعر

Advanced Design of Work Roll Contours for Different Roll Mill Types ...

Thus, this paper presents the effects of various work roll contours designed for (1) the 6th and 7th stand of a 4-high hot tandem rolling mill; (2) single stand 6-high reversing cold mill; (3) 1st to 3rd stands of a 6-high tandem cold mill. Results show that the NGOS strip profile hit rate of 5 micron-meters is increased by the implementations ...2.1 Establishment of the FEM for 6-high TCMs. With the rapid development of computer systems, the FEM has been widely used in the rolling process. In order to analyze the shape control efficiency curves of the 6-high TCMs, a 142-0 mm 6-high TCM production line for non-oriented electrical steel and the self-developed EDW-N work roll is taken as the research objects.Transverse thickness profile control of electrical steel in 6-high cold ...Rolling schematic view Rolling visualization. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough.Rolling is classified according to the temperature of the metal rolled.Rolling (metalworking) - Wikipediaاحصل على السعر

Multi Optimization of Intermediate Roll Profile for a 6 High Cold ...

Profile for a 6‐High Cold Rolling Mill ... The equivalent crown Ce of the roll gap is the difference of roll gap between the center and edge, which can be calculated as in Equation (7). ...However, most of the cold rolling mills are 6-high UCM rolling mills or 4-high CVC rolling mills. Given that the 4-high CVC mill has work roll shifting function, it can use the K-WRS technology to realize similar function of the 6-high UCMW mill . However, the edge drop control capacity of the 6-high UCM rolling mill is obviously insufficient ...Research and Development Trend of Shape Control for Cold ... - SpringerOpenHot rolling is the rolling of steel at high temperatures. The performance advantages of cold rolled sheet versus hot turned sheet are: (1) Higher precision, cold-rolled strip thickness difference ...The difference between hot rolled and cold rolled coils - LinkedInاحصل على السعر

Modeling and validation of bending force for 6-high tandem cold rolling ...

As shown in Fig. 3, the UCM 6-high cold rolling mill is based on the ordinary 4-high cold rolling mill with the addition of an intermediate roll that can shift laterally between the work roll and the backup roll.Through the hydraulic roll bending system, applying a variable bending force to the end of the work roll or intermediate roll instantaneously changes the effective roll crown, thus ...Ma et al. developed a symmetrical tapered work roll contour for a six-high reversal mill and claimed that the controlling width was 100 mm. Furthermore, given that the 4-high CVC mill has work roll shifting function, it could use the T-WRS technology to realize similar function of the 6-high UCMW mill .Edge drop control characteristics of the taper-work roll contour for ...Product description The diameter of the 6-high work rolls amounts to approximately 1:4 in relation to the barrel length.

Ways to Classify Rolling Mills Although there are several different types of rolling mills, they are generally classified by the temperature they operate with: cold or hot. In a cold rolling mill, metal is pressed through the machine, and the cold temperature actually hardens the metal.The performance of a conventional 4-High mill is not satisfactory in these requirements.
