TMEIC provides electronic equipment for cold mills such as the power-supply system, drive systems, automation, and process technology, all based on extensive mill experience. TMEIC provides equipment including the Mash Seam Welder (MSW), the Flash Butt Welder (NMW), and a Laser Beam Welder (LBW). These welders support high productivity for a continuous line. Cold Mill Line Scheme Main Functions of the Cold Mill
TMEIC Supplies Superior Control Systems for Hot Rolling Mills Hot rolling mills roll heated steel, stainless, and aluminum slabs to make hot strip with a thickness of a few millimeters to over ten millimeters. Hot coils are shipped as they are, or moved to another operation and processed to cold rolled sheet, coated steel sheet, or steel pipe.
1/1/2015· the cold mill, continuous annealing line, and continuous galvanizing line use state-of-the-art technologies incorporated in the TMEIC process automation and control system. TMEIC supplied the complete electrical equipment for the mills and process lines including TMEIC motors, drives, automation hardware, and process sensors.

Every aspect of JSW PLTCM is designed to add precision and quality control to the cold rolled process. In this, pickling line is linked with cold rolling mill, which provides better shape control, delivers significant improvements with regard to mill productivity, yield, and production as a result of the elimination of strip threading and tailing-out operations.
Cold Compact Mill (CCM) Pickled coils are rolled in twin stand cold rolling mill where they are processed into a specified thickness. Generally, the rolling reduction ratio is 50% to 90%. The critical point at this stage of the process is to maintain uniform and precise flatness throughout the entire length of the coil. Unique Features
Mechanics of Cold Rolling of Thin Strip 441 rolling force and torque, and the strip plastic deformation such as the strip shape and profile. A comparison of the forces and the st rip shape with or without the work roll edge contact was carried out. The effects of the diff erent rolling parameters, such as
TMEIC GE’s hierarchical automation system, developed over 50 years of steel rolling mill experience, provides control based on physics- based computer process models, called Level 2, which supply references (or setpoints) to, and are tightly integrated with, the Level 1 PLC control.

The committee then discussed the creation of a Cold Mill Roundup to be published in a future issue of Iron & Steel Technology. Volunteers were solicited to gather data for the Roundup. Brian Smith reviewed the 2018 Cold Rolling Fundamentals — A Practical Training Seminar, which was held in September 2018 in Huntsville, Ala., USA, in conjunction with the System Automation Fundamentals training course.
The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

Chinese copper manufacturer Chinalco Shanghai Copper has been operating a single-stand reversing cold mill from SMS group since January 2011. The 6-high stand with CVC ® plus technology rolls copper and copper alloy strip from a starting gauge of up to 4.0 mm down to final gauges of as little as 0.15 mm. The annual capacity exceeds 100,000 tons
Mill Roll for HSM,Cast Roll for hot mill, Forged Roll for . We focus on supply high quality rolls for hot rolling mills and cold rolling mills with reasonable price and delivery. Company Factory Now our roll manufactory annual output is 12,000tons, more than 4000tons export to all over the world.
In the hot strip mill process of the iron and steel industry, heated slabs (about 250mm thick and 10m long) are rolled to is used to control the rolling speed of each mill to smooth the threading of the strip. During strip thread-ing, mass flow unbalance (which affects the strip tension and dimensional quality and successful mill . Get Price
Cold Mill Systems TMEiC. A Cold Mill rolls coils of pickled steel from the pickle line at ambient temperature, make corrections to the delivery stand which maintains strip flatness and quality. techniques to change the gap position to compensate for roll eccentricities.get price
A reversing cold rolling mill has been suffering from such drawbacks as unrolled portions necessarily produced in head and tail ends reduce yield, and time consuming works including removing of coils, threading of the strip and holding of the strip with the tension reel, which result in decreasing productivity.
