Multi-roll cold rolling mills are used to process high grade steel strip and non-ferrous metal strip. In order to prevent whipping of the work rolls, they are supported by means of intermediate rolls and support shafts. Several back-up rollers are arranged adjacent to each other on these support shafts and separated by support saddles.

What is claimed is: 1. In combination a rolling mill for rolling hot slab into plate or strip and having opposed horizontal upper and lower work rolls and work roll chocks in which said work rolls are mounted, stripper guides being disposed adjacent to the work rolls on the exit side of said rolls and each having a single stripper guide roll rotatably mounted therein, the respective stripper ...
Piling-up of steel means that during the continuous rolling process, the metal second flow rate of the downstream frame is significantly smaller than that of the adjacent frame, and a large amount of metal accumulation occurs between the two frames, so that the stability of the rolling stock is destroyed or even a failure phenomenon of rolling ...
135M Finishing Mill Group. The finishing mill group is the extra-heavy top cross 45° high-speed wire-rod finishing mills designed for the high-speed wire-rod production line. The finishing mill group is located in the high-speed wire-rod workshop. Rolling by 10 unit rack continuous micro-tension rolling mill, rolling the ∅17 ~ ∅21mm of ...
Chock is the basic part of a rolling mill. It is mounted in the window of the roll stand housing between the posts with a small clearness. The roll stand housing encloses and supports the chock assembly. The chock also prevents scale getting into the roll neck bearing. The process stability of rolling mill is significantly influenced by the ...
A three roll mill has three horizontally positioned rollers. Each roller rotates in an opposite direction from the adjacent roller with a tiny gap between them, creating tremendous shear force that can finely disperse, mix, refine or homogenize viscous materials.
Adjacent rolls rotates in opposite direction. So that the material may be passed between the top and the middle roll in one direction and the bottom and middle rolls in opposite one. ... In two high reversing rolling mills the rolls rotate ist in one direction and then in the other, so that rolled metal may pass back and forth through the rolls ...
A magnesium hot rolling mill system including a rolling mill having at least two work rolls for rolling of magnesium sheet or plate, a hot coiler positioned on either side of the rolling mill for heating and maintaining a desired temperature of the magnesium sheet or plate, active thermal roller tables, a mill drive system for independently driving the work rolls for asymmetrical rolling of ...
Monongahela Furnace Company constructed two blast furnaces on property adjacent to National Rolling Mills Company, which was later to become the nucleus of the present steel works. 1890: No. 9 and No. 10 lap weld furnaces were built, and …
Rolling mills are computer controlled with complex automated drive systems. Overall, rolling mill equipment is expensive and can take a long time to repair or replace, even when slight damage occurs. ... Mill drive motors are usually located in a room adjacent to …
1 INTRODUCTION. Roll wear reduction is an effective way to save production costs and increase the productivity of the hot strip rolling mill. 1, 2 The continuous variable crown (CVC) roll wear is a seriously concerned since this technology has been used widely. Using CVC technology, the variable roll gap crown can be obtained by the artful roll shifting mechanism. 3, 4 As an innovative ...
The mill is capable of rolling even high alloyed speciality steel. After the closure of the adjacent Nirosta steel mill all primary material now comes from the August Thyssen Hütte in …
The intermediate roll allows for a reduction of the work roll diameter further than can be achieved with the four-high mill, since the ratio of two adjacent roll diameters are kept low The intermediate roll can be equipped with a side-shift mechanism with which the rolls can be moved laterally in and out over the strip edge during rolling.
What is Rolling Mills? The invention of the rolling mill in Europe may be attributed to Leonardo da Vinci in his drawings. The earliest rolling mills in crude form but the same basic principles were found in the Middle East and South Asia as early as 600 BCE.
2: Three high rolling mill: It consists of a roll stand with three parallel rolls one above the other. Adjacent rolls rotates in opposite direction. So that the material may be passed between the top and the middle roll in one direction and the bottom and middle rolls in …
Moreover, since the variation in the finished strip thickness is controlled by adjusting the rolling speed of the antepenultimate rolling stand 13, which is located more upstream than the stand 14...
It is found that self-oscillation significantly affects the fluctuation of the longitudinal stress in the metal and the rolling forces in adjacent stands of the continuous mill; and only slightly ...

The CO gas produced in Tornio at Outokumpu's ferrochrome production process can be used to fuel downstream processes such as the adjacent hot-rolling and cold-rolling mills. Excess CO gas is also utilized by the Tornion Voima power plant located at the Group's site. Outokumpu produced 1.4 million giga joules (GJ) of CO in 2008.
The standard control concept, which is currently implemented in many industrial tandem rolling mills, consists of multiple (coupled) control loops and is outlined in Fig. 2. This figure covers two adjacent mill stands and the looper and strip in between. The index n refers to variables that concern the mill stand n or the looper n. The control ...
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 recoil temperatures and inter-stand strip temperature rarely exceeding 160 oC depending on product.
Rolling mills for rolling of steel differ in many aspects with each other. ... The intermediate roll allows for a reduction of the work roll diameter further than can be achieved with the four-high mill, since the ratio of two adjacent roll diameters are kept low The intermediate roll can be equipped with a side-shift mechanism with which the ...
