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.
With most modern infrastructure and more than 100 man years of process knowledge, YOGIJI DIGI is offering efficient modern Cold Rolling Mills that produce ultrathin gauges at tightest tolerance with high productivity and advanced features. As specialists in the field, YOGIJI DIGI is invited to resolve the issues in existing mills.
The unit operates at higher pressure, which enables it to produce thicker, drier solids discharge, as well as better filtration throughout the cold rolling mill process. The cold rolling oil filter also has a minimum of moving parts, as it does not clam shell open and close, which provides better overall plant hygiene, reduced maintenance costs ...

Umumnya, materi kerja yang mengalami coldrolling jauh lebih kecil dan memiliki kekuatan yang lebih besar dibandingkan dengan materi yang mengalami hotrolling. Four high atau cluster mill diperlukan untuk proses cold rolling. Namun, cold rolling tidak dapat mengurangi ketebalan materi kerja sebanyak hot rolling dalam single pass.

The most common configuration is the single reversing mill. Various mill designs are offered that include 6high UCMs (Universal Crown Control Mill), ZR mills and 12high coldrolling mills with smalldiameter work rolls for the efficient rolling of materials of high hardness.
This paper focuses on the various optimization techniques used in cold rolling mill process to achieve productivity and Quality of steel through literature review. Various Process models for cold rolling mills have been intensively developed in the last years, hoping to increase quality of steel strip and productivity of rolling processes.
COPPER COLD AND FOIL ROLLING MILL UCMMill and XMill Technology for thinner foil rolling. For copper cold rolling and foil rolling, several types of mill are selected according to the rolling process, thickness and materials to be produced. Our typical mill type is the UCMMill, which is suitable for rolling .
The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by fabricators. Billets, for rerolling, are subsequently rolled in either a merchant, bar or rod mill. Merchant or bar mills produce a variety of shaped products such as angles, channels, beams, rounds (long or coiled) and ...
