Nov 22, 2013· Cold rolling using Roll Coolant emulsion In this CRM, Cold rolling is done on a Mecon Weanunited PLC controlled 3000 tons/m 4 Hi reversible mill. As the name suggests the 4 Hi mill employs 4 rolls, two these are the work rolls and the other two are the backup rolls.
With mill speeds of up to 1400 meters per minute, high levels of productivity and costeffectiveness are guaranteed. Rolling schedules can be possible with an even and uneven number of passes. Work roll positive and negative bending are the additional features provided for better shape control.
Next, the slabs pass through a 4high reversible roughing mill, coil box and rotary crop shear before heading to the finishing mill. Once passing through the 6stand, 4high finishing mill, the steel will be between 35 in. and 53 in. wide and in. through in. in gauge.
COLD ROLLED COILS SHEETS We offer high quality Cold Rolled coils are processed in the rolling mill to reach the thickness as per customer''s specific requirement. The reversible rolling mill is equipped with automatic gauge measuring unit on each side to have a precise control on thicknesses and minimum tolerances.
20HS mill rolling mills from SMS Group technology that pays off. You benefit from our 20high mills because they are packed with stateoftheart mechanics, hydraulics, electrics, and automation. Plus: it''s easily possible to retrofit these features into existing mills.
Tension bridles for a cold rolling reducing mill are provided. The reducing mill reduces the thickness of a metal strip passing through the reducing mill. The tension bridles create tension on the metal strip between the bridle and the first reducing stand to receive the metal strip and between the final reducing stand and the exit bridle so that a greater reduction can be made in the ...
Aug 01, 1992· The high precision Fourhigh reversible cold rolling mill was successfully completed in Shanghai in 1989, all the work of the project, including design, manufacture, installing and test, was done with the cooperation of Shanghai Metallurgic Equipment General Factory and the University of Science and Technology Beijing.

The cluster mill that this study aims is a 20high reversible mill. With reversible mills means that once the strip has been coiled from the decoiler to the recoiler, the rolling direction is reverted and the decoiler becomes recoiler and vice versa. The mill contains of an upper and lower mill housing of rolls, see figure 1.
on wear is another issue. Stresses from Hertzian pressure in 4high cold mill back up rolls were measured years ago, the results were never published, but of high interest also, maybe later. K. H.

shape roll. In a foil rolling mill (for a material with a thickness of to mm), a shape roll is fixed as shown in Fig. 6(a) and a wrap angle is adjusted by changing the height of the tucking roll. In a cold rolling mill where the material is thicker and the tension is higher compared with a foil rolling mill,
6 Hi single stand, high tension, reversible mill is installed for cold rolling of the pickled coils to the desired thickness as low as Mill has all the capability and capacity to produce cold rolled sheet of practically table top flatness.

Nov 28, 2017· In twohigh reversing rolling mills, the rolled metal may pass back and forth through the rolls several times. The disadvantage of reversing mills is that the rolls must be stopped, reversed and then brought back up to rolling speed between each pass. The threehigh mill was invented to resolve this drawback.

Danieli Wean United cold rolling technology (4high and 6high) allows a superior strip quality in terms of surface and profile, with lower production and maintenance costs, being able to fulfil the highest demandes of production flexibility and plant efficiency.
The single reversible cold rolling mill is divided into the fourhigh mill and multihigh mill (partial eighthigh mill, Twelvehigh mill and twentyhigh mill). Most rolling mills are driven by working rolls, which can reduce the total deformation resistance, reduce energy consumption and roll thinner products.
CVC mill''s cambering, not suitable for 4 high cold tandem mill. So, the emphasis of field breakthrough is how to effectively control the complex wave defects of four high cold mill from the point of roll configuration curves. For this reason, after lots of field experiments and theory research, a new technology of cambering
