The successful twinstand Compact Cold Mill (CCM ®) was originally invented by SMS we have by far the most CCM ® references worldwide. Featuring a capacity of up to 900,000 tpy, the CCM ® closes the gap between the singlestand RCM and the multistand tandem cold mill. We engineer these mills to achieve the best investment and lowest operating costs for their capacity range.
We applied the proposed model to multistand rolling (roughing train of POSCO No. 2 Rod Mill) as well as singlestand reversible rolling. The wear profile of rolls worn down at each stand in mill ...
Other methods of compensating for roll deformation include continual varying crown (CVC), pair cross rolling, and work roll bending. CVC was developed by SMSSiemag AG and involves grinding a third order polynomial curve into the work rolls and then shifting the work rolls laterally, equally, and opposite to .

A 300mmwide strip 25mm thick is fed through a rolling mill with two powered rolls each of radius = 250 mm. The work thickness is to be reduced to 22 mm in one pass at a roll speed of 50 rev/min. The work material has a flow curve defined by K = 275 MPa and n =, and the coefficient of friction between
The threehigh mill was invented to resolve this drawback. Reversing mills are more expensive than nonreversing rolling mills due to their reversibledrive requirement. The purpose of the reversing mill is to reduce the thickness of the steel to the customer''s specifications. The hot roll band passes back and forth between the rolls until it ...
XT MILL ROLLS NORTH AMERICA, Mill rolls, employed in rolling all types of steel and nonferrous metals, carry high technology and high additional value in the processes of smelting, casting, heattreatment and machining etc., Web Design: E IMAGE INC.,
To determine the amount of roll gap adjustment, we propose a model for equivalent roll gap decrement which reduces the increased exit cross sectional area due to wear. We applied the proposed model to multistand rolling (roughing train of POSCO No. 2 Rod Mill) as well as singlestand reversible rolling.
Single Stand Single Coiling Aluminum Hot Rolling Mill . The rolling process is carried out on a reversible rolling mill, and the ingot is coiled after reciprocating rolling. The minimum thickness is 7 mm, and the production capacity can reach 150,000 tons per year.
Dec 13, 2013· In a Hot rolling mill especially in a steel industry where highly integrated automation is used for high quality steel strip production, how roll change can be done in .
motors. These are known as mill stands. The layout of a rolling mill varies, from a simple single stand mill to several stands positioned either side by side or in a line. A mechanism, commonly called a roller table, directs the work piece to the rolls, and another roller table for handling the pieces emerging out of the roll.
Singlestand mills include most blooming mills, slab mills, ballrolling mills, and mills for the cold rolling of sheets, strips, and tubes. Mills with several roll stands are used when it is impossible to place the required number of grooves in one roll stand or when a high output is required.
Oct 24, 1972· A universal mill stand according to claim 1 including reversible roll driving motors operatively coupled to said rolls to effect reversing rolling. 3. A universal rolling mill stand for reversing rolling of profiled beams comprising: 4. A universal mill stand according to claim 3 wherein the universal mill stand is a twohigh mill.
May 19, 1998· An improved roll shifting system for rolling mills comprising a pair of work rolls positioned on each side of the rolling plane, a pair of upright frame posts defining an opening in which chock guides are mounted facing the opening and chocks on each axial end of each roll.
The roughing mill also contains edger rolls that are used to roll the edge of slab and center it. A rectangular head end is critical to thread the finish mills and down coilers properly. An uneven tail can damage workroll surfaces or cause threading problems for the next production process.
The project consisted in the complete rolling mill automation starting from the reheating furnace to the cooling bed area, including the following sections: Reheating furnace automatic billet charging, discharging and temperature control; Single stand reversible roughing mill; Five stands roughing mill to feed the small and medium section lines
Failure analysis of work rolls of a thin hot strip mill. ... In hot rolling mills, premature failure of rolls is a major concern. ... stand where the thickness is reduced further but the reduction after each single pass is much less as compared to a single pass in roughing stand. The finishing stand consists of 4 sets of rolls in F#5 to F#6.
