Strip drying system. The process of cold rolled steel strip and aluminum strip coiling requires dry and free of spots. SMS this strip drying system was developed. Cold rolling mill in accordance with the use of cooling and lubrication system, that is, only the entrance side of the entrance side of the tail end or tail end and transmission coolant and lubricant use, need a different solution. To the entrance side of the coolant and lubricating fluid with the use of the development of dry (DS) system. Strip drying system includes both fully proven technology with newly developed technology to non contact drying of cold strip production.
Innovative aluminum rolling mill
Elval six roll strip rolling mill
Elval the Hellenic Aluminium Industries SA of Greece Viohalco Group, Inofita Viotia subsidiary, which is Europe's top aluminum producer.With the volume of its annual production capacity of more than 1 million tons. In early 1999, with Europe's largest hot rolling mill of the Elval to SMS ordered a rolling aluminum and aluminum alloy for the new cold rolling mill. Plans to put into operation in December 2000.
New mill, will produce 1000,3000 and 5000 series prerolling and finishing of aluminum billet and aluminum. Strip width from 1,250 mm to 2,300 mm, maximum thickness of 6.0 mm at the entrance side, in the export side of the minimum 0.15 mm. Maximum coil weight is 32 tons, maximum diameter of 2600 mm.
Elval mill modulus method is a One (AIO) designed to include all the parts, that is, the rack is exhaust systems, maintenance platforms, all hydraulic valve seat, pipes, cables, control panel and separate separation of the two Mill Church device.
Is a six roller mill, a continuously variable transmission of the crown twitch intermediate roll, work roll with the horizontal stabilizer (HS) system. According to the task of rolling the option of breeding work roll diameter. This increased flexibility in the mill, and to optimize the final product. Best of the roller diameter, the rolling force of 24,000 kN, and 1800 m / min rolling speed, the total installed capacity of 9800 kilowatts, and the maturation process control systems and Siemens AG has found that the transmission project to ensure that the product high quality and high yield.
Rolling Road, adjustment of the polar wedge mounted on the bottom rack to maintain a continuous roll. This design first used for a large range in the ground and in the adjustment.
This sets the ultimate control of rolling mill installed the following components:
A low friction cylinder hydraulic pressure adjustment
Work roll and intermediate roll bending
CVC intermediate roll tic, tic stroke of + / 150 mm
Multi lateral part of the cooling and the cooling inlet
he level of work roll stability (HS)
The final control unit (in addition to the level of work roll stabilization (HS system)) are in the flatness and thickness of the closed loop control system operation.
VAW Aluminium transformation of three strip mill
Germany's largest manufacturer of aluminum and aluminum foil VAW Aluminium AG recently called SMS extensive plant to enhance its two cold rolling mill in Hamburg and a hot rolling mill performance. VAW selected SMS's "complete" solution, including extensive automation Levels1 and 2, a process control system and rolling ahead of schedule calculation. In addition to new mechanical and hydraulic components, the contract also covers the cooling system, the basic system automation and electric drive system, and all associated equipment dismantling and restructuring. In addition, the first test cold rolling mill renovation plan in late 2000 / early 2001. The other two were in the mill plans to run six months and one year later.
The width of the last production to 2900 mm from 2650 mm four high reversing strip hot rolling rack, will install new hydraulic adjustment cylinder and a stronger work roll bending cylinder. The export side of the rack with the new thickness, contour and temperature control systems, and contour and thickness of the scale measuring devices, such transformation can reduce the tolerance strips, contour control increases.
