5 racks, three racks are four roller, and the other two racks are set up six high CVC
2 direct drive roll tension
All from low carbon steel to stainless steel cold rolling stock emulsion system
Strip down the side of the line detection
Thyssen Krupp Stahl continuous pickling and rolling production line. Now, the German Thyssen Krupp Stahl in Duisburg Beeckerwerth plant a new five stand tandem cold rolling mill under construction. The existing rolling mill and the pickling line connections, and for the production of thin strip and the design of high strength materials. Therefore, the mill concept is based on the largest possible range of roll gap settings.
All five racks are modular in one design method, using a six roller CVC. The width of the rolling mill from 1000 2040 mm low carbon steel and HSLA steel. Feed hot strip thickness of 1.5 to 6.5 mm, cold rolled low carbon steel of the material thickness of 0.3 to 4.0 millimeters. Maximum rolling force of 33,000 kN per rack, installed capacity of 32.4MW. It is the world's strongest performance of one mill. Maximum rolling speed is 1500 m / min. Capacity of 2.1million t / a.
Controlled rolling process measurement devices. Strip tension, thickness, speed and smoothness control the composition of the total gap control. Over and above the final control components, such as hydraulic pressure, work roll and intermediate roll bending, work roll cooling system parts, the first computer with a serial device to strengthen tic mill.
This sets mill some salient features of the other is part of the strip test for all grades of steel metastable emulsion system enabling mill clean sheet , the new strip drying system, automatic replacement of intermediate roll and work roll, and pickling line and rolling mill in a special connection between the devices.
Two stand reversing mill. Small rolling mill for flat products, equipment needed to produce 8 million to the economy 9000000t / a cold rolled strip. Tandem mill and a single reversible rolling mill can not achieve such yields. The development of the compact SMS Cold Rolling Mill (CCM) to fill the gap, which is to reach more high quality low cost production mill.
CCM is based on a new three rolls were installed two racks. Product portfolio according to two racks, strip width, thickness and strength design for four or six rollers roll. Compact cold mill work roll or backup roll by you can drive two racks. With the support roller drive, a work roll work roll change can be introduced in less than 150 seconds to complete. The biggest advantages of this technology is that the rack can be quickly replaced on the last roll, so rolling a strip of different surface structures.
Compact tandem cold rolling mill was also installed in that ultimate control of all high tech components. This form of the first mill in the United States two years ago, Butler's Steel Dynamics successfully put into operation. Not only to achieve the planned yield curve, and ahead of schedule.
Reversing mill steel foil
SMS Germany Wickede the Wickeder Westfalenstahl GmbH built a six roller reversible cold rolling mill CVC, particularly for the production of thin strip cold. This table represents the rolling mill steel foil thickness down to 15μm great progress. Rolled strip width from 400 to 1000 mm, rolled steel wide range of applications, including deep drawing and strip for the non alloy and micro alloy steel, non alloy and low alloy hardening steel, as well as steel and heat treatment spring steel.A special product is the band for television tubes the shadow mask material, thickness tolerance is ± 1μm, able to meet the highest requirements on the surface.
High production requirements is through the use of high tech system components to achieve. Specific performance rolling mill roller bearing direct drive and to ensure highly dynamic and reversible non slip reel drive. Wide range of work roll diameter from 140 240 mm, rolling the entire product range. The concept of low friction rack system implementation. Rack is designed to use 100 mm diameter work roll, so that the minimum thickness of strip to 25μm. Rack level components have a bearing roller positioning system, the level of stability intermediate roll (HS), intermediate roll layer CVC technology and SN series MORGOIL bearings. The premise of the highest surface requirements for the rough rolling and finish rolling there are two separate emulsion system, they have speed control supply pump, vacuum filter, magnetic separator and skimming equipment.
