There are mill automation systems and product optimization. These components of the SMS new high tech idea that the whole roll gap control system (TRC).
Another new technology is the work roll and intermediate roll technology to strengthen the tic (ESS). This technology adapted to the rolling of high strength materials, the highest requirements, obtain the minimum thickness of the final strip, and has a broad portfolio of products.
SCR Roll
Hydraulic expansion of SCR (Special crown roller) bearing roller for aluminum strip and foil rolling mill specially developed, but can also be used in the two roll and four roll mill on the strip. The use of SCR Roll mode can improve the closed slit strip and foil rolling mill in the material quality of the edge. And have other benefits, such as fracture reduction in the number strip, work roll and extend the service life of bearings, rolling faster.
SCR as the traditional roll Roll, like a roller in the roll axis, but the end of the extension of the formation roller cone. Tapered sleeves inserted into the expansion cracks, no gaps, the axial position. Hydraulic oil through the hole to reach and cross roller bushings and roller cone gap between. Adjusted by changing the hydraulic roll in the shape of strip edge region.
SMS mill control and flatness control automation system is fully integrated.
No hydraulic oil when the roll contacts the metal parts can be as traditional as Operation Roll.
Roll no internal moving parts. Hydraulic connection media and roll rotation coupling through the middle, so the roll can have a common hole.
SCR Roll without the use of the work rolls warm, and make continuous rolling possible. This production also has a positive effect. Roll using the SCR VAW Aluminium AG in Germany foil roughing mill (four roll) of the operating results.
Strip surface inspection. Surface quality of cold rolled strip and higher requirements for the most advanced filtration technology required for cooling and lubrication systems.Due to the continuous growing use of the rolling process, feed and out feed roller when the damage has been greatly reduced. However, testing the surface of cold rolled strip is still essential. The earlier detection, less waste. With the new online testing system that can run the strip on the cut from 5 meters to 10 meters, directly in the continuous or continuous cold rolling mill on the test. Therefore, in the case of a surface defect, you can take immediate action, such as the replacement roll.
EDC cooling system
EDC (edge of the sink control) cooling system, first for the two cold rolled (DCR) the development of tin plate mill, and its main purpose is to suddenly reduce the hot roll strip edge in the crown area, to compensate for sinking the edge strip. In addition to the ordinary work roll cooling, cooling spray for the EDC to set in work roll set tube to export or import side. Basic cooling system using basic common supply temperature of the cooling fluid, lotion or cold oil; edge cooling using the cooling of the emulsion, rolling oil or water, so that the edge region has sufficient cooling to achieve a suitable hot roll crown.
EDC roll system. EDC is the first work roll tin plate mill for the design of the DCR.These characteristics of the roll at one end of its barrel a ring notch. Tic system enables long stroke axial roller to accommodate different strip width. Edge of the sinking of compensation depends on the roll shell and strip the degree of overlap between the edge.
