Applications

TMEIC Supplies Superior Control Systems for Hot Rolling Mills

Hot rolling mills reduce heated slabs of steel, stainless, or aluminum into thin strip used in automotive, rail, and appliance applications. These coils are either shipped directly or further processed into cold-rolled sheet, coated products, or pipe.

TMEIC supplies complete systems—including high-power drives, automation, and process control—to ensure precise control of thickness, shape, and cooling for optimal material strength. Our experts perform vibration, speed, and electrical simulations to configure motors, drives, and transformers for each mill.

Operator stations feature ergonomically designed controls and real-time HMI monitoring for continuous performance oversight.

Precision Solutions for Plate Mills

TMEIC delivers integrated power, automation, and testing systems for rolling mills that produce high-strength steel plates used in shipbuilding, infrastructure, and industrial machinery. Our technology ensures reliable performance and consistent product quality.

From mill setup and drive systems to process automation and Ultrasonic Testing, TMEIC helps plate mills maintain tight control over thickness, width, crown, flatness, and temperature. Advanced features like Temperature Controlled Rolling (TCR), Automatic Gauge Control (AGC), and Crown & Flatness Control allow for precision shaping of multiple plates in line—an innovation first achieved by TMEIC.

Advanced Automation for Cold Rolling Mills

TMEIC provides comprehensive electrical and automation systems for cold mills that roll pickled steel, stainless, aluminum, copper, and foil at ambient temperatures. Our solutions support various mill types—from 2-High to 20-High and Sendzimir mills—with precise flatness and thickness control.

We supply drive systems, power equipment, and process automation alongside high-productivity welders like the Mash Seam Welder (MSW), Flash Butt Welder (NMW), and Laser Beam Welder (LBW).

Core Capabilities Include:

  • Crown & Flatness Control: Maintains strip geometry using real-time sensor feedback.

  • Automatic Gauge Control (AGC): Regulates strip thickness with feedforward, feedback, and mass flow methods.

  • Eccentricity Compensation (ECC): Offsets roll irregularities to ensure uniformity.

  • Tension Control: Optimizes strip tension between stands and reels.

  • Flying Gauge Change (FGC): Enables smooth transitions between product orders.

  • Cold Mill Setup (CSU): Calculates optimal speed, tension, force, and thickness settings.

TMEIC also offers modernization paths for tandem cold mills and aluminum foil lines—transitioning from DC to AC motors to reduce maintenance, boost responsiveness, and improve drivetrain performance.

Integrated Systems for Steel Process Lines

TMEIC delivers complete electrical and automation systems for process lines that transform hot and cold rolled coils into finished products through pickling, annealing, galvanizing, coating, and shearing.

We provide drive systems, power distribution, and precision control across every stage of the process—and are global leaders in supplying seam, flash, and laser welders that support continuous operation and high productivity.

Supported Process Line Types:

  • Pickling Lines

  • Galvanizing Lines

Section and rails are produced using caliber rolling mills and universal rolling mills

TMEIC provides integrated automation systems for section mill plants—from billet rolling through finishing operations like cooling, reforming, cutting, and piling. Our Mill Master Control platform manages critical functions including screw-down, roller table speed, cut-to-length, and finishing sequences with seamless coordination.

We support bar and wire rod mills with high-speed controls such as Free Tension Control (FTC), loop management, impact drop compensation, and front-end positioning. These mills demand ultra-fast systems—rolling wire at over 100 m/s—to ensure dimensional accuracy and product quality for applications ranging from construction to automotive parts.

TMEIC also delivers robust solutions for seamless pipe mills used in oil and gas. We provide high-speed, dynamic control systems for temperature drop and wall thickness regulation, enabling accurate, consistent pipe production.
