Rolling (metalworking) - Wikipedia
To minimize the roll diameter a four-high or cluster mill is used. A small roll diameter is advantageous because less roll is in contact with the material, which results in a lower force and power requirement. The problem with a small roll is a reduction of stiffness, which is overcome using backup rolls. These backup rolls are larger and contact the back side of the smaller rolls. A four-high ...

GENERAL ASPECTS OF ROLL COOLING FOR HOT & COLD …
rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills. Cooling and lubricating is furthermore essential for the plateout for ...
Fundamentals of Roll Cooling and Control of Flatness at ...
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. Roll Bite temperatures in slower heavily drafted stands can peak in the region of 300oC, diminishing with the reducing thickness and increasing speed in the downstream mill ...
Robust Tension Control of Strip for 5-Stand …
Tension control is one of the most important process parameters in tandem cold mill (TCM). Changing roll velocity stabilizes the interstand tension . Interstand tension should be maintained at acceptable levels. Large transient variations in tension may result in a dramatic and physically damaging failure of the mill through looping, where the strip tension falls to zero, or tearing of the ...

This mill is used to cold-roll brass and copper into thin sheets. It is not possible to use flying micrometers for thickness measurement of this material because of the high degree of surface finish which is required and the malleable nature of the material. The mill produces brass strip up to 40 cm width and 0.1 mm thickness at rolling speeds approaching 200 m/min. The thickness of brass on ...
