Hot Rolling Mills | TMEIC

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. Products are used in various applications such as for automobiles, rail cars, and home appliances.


TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS MILL DRIVES FOR GRINDING APPLICATIONS M. Ahrens, ABB, Switzerland J. Gonser, ABB, Switzerland Abstract Gearless mill drives are a well established solution for grinding applications in the minerals and mining industries. The paper describes the functionality and technical features of such drive systems as well as their

Motors for Metal Rolling Mills | TMEICAC adjustable speed motor drive systems are the preferred technology for new rolling mill installations and modernization projects. TMEIC designs and manufactures two types of AC solutions for this purpose. Salient pole synchronous motors that meet the high power and torque demands of a hot strip mill, as well as roughing and finishing stands.EE 6361 ELECTRICAL DRIVES & CONTROLBasic elements-types of electric drives-factors influencing electric drives-heating and cooling curves- loading conditions and classes of duty-Selection of power rating for drive motors with regard to thermal overloading and load variation factors Unit-II Drive motor characteristics Mechanical characteristics- speed- torque characteristics of various types of load and drive motors - braking of

M. Keyßner, T. Fahrland, Loesche , Duesseldorf the electric motor to the selected mill speed and to transmit the torque created by the motor. Secondly, the gearbox has to transmit the grinding forces generated by the grinding rollers, from the mill table, through the gearbox, into the mill foundation. Today, most mills are equipped with bevel planetary gearbox - es that are driven by a single electric motor, with two-stages used for drive

Get priceTop 7 Benefits of Using Variable Frequency Variable frequency drives, or VFDs, are a type of AC motor controller that drive an electric motor by varying the frequency and voltage supplied to it. VFDs are also commonly known as variable speed or adjustable speed drives, AC drives, micro-drives or inverters – depending on the industry or application.How to select a motor for an industrial Brush wear is not an issue with ac induction motors and a variable frequency drive (VFD) creates a useful choice for applications over 1 hp such as fan and pumping applications, which lead to improved efficiency. The type of drive chosen to run the motor can add some positional awareness. An encoder can be added to the motor if the application requires it, and a drive can be specified to use
