Monitoring System for Roll Stand Drives Using Strain Gage Technology

Calculation and construction of the tolling roller table

“…2(b)) do not exceed the maximum permissible value for the given material's strength 640 MPa. In this case, the maximum values of stresses and deformations are observed in the teeth and necks of the gear wheels [5,6]:…”

“…These rollers satisfactorily provide the quality requirements for the strip surface [5]. However, the overwhelming majority of them, in addition to relative advantages, have a significant disadvantage, such as: increased metal consumption, low wear resistance, the presence of a large number interfaced elements, the complexity of design schemes complicating the installation and dismantling work, short life [6]. These shortcomings in the conditions of metallurgical enterprises characterized, as a rule, by a mass or large-scale type of metal production, lead to significant downtime of equipment and roller tables, in particular.…”

Calculation of the stress-strain state of the deflector rollers

“…-As a whole, the value elastic deformation of the elements of the rollers is small, which indicates a decrease in the effort of the proposed outgoing roller table produced on the rollers [7,8]. This guarantees the possibility of reducing wear and breakage, as well as the failure rollers of the proposed roller conveyor.…”

“…A prerequisite for preventing damage to the surface of hot-rolled strips is also the maintenance of a high level of technical condition of the mill equipment, which includes inspections of wiring armature bars, roller conveyor rollers and other units for each transshipment, timely replacement and repair of individual parts and assemblies (primarily roller conveyors, interroller plates, etc.) [7]. It should be noted that the rollers of the roller conveyor, is one of the massive elements, is subject to heavy wear and frequent breakages, which leads to significant roller conveyor failures.…”

Development and Application of On-Line Torque Telemetry System for Rolling Mill based on WIFI Signal Transmission and High Frequency Induction Power Supply

“…The real-time on-line monitoring of equipment state can provide reliable and useful data information for the production process, so as to ensure the safe and efficient operation of the equipment, therefore all countries in the world are actively engaged in the development of the on-line real-time monitoring system of the equipment state.In 1995, the University of Aachen in Germany developed data for measuring the torque of the upper and lower roller drive shafts [1].In 1998, Andreas Asch, Wolfgang Hohn developed a new torque measuring device based on strain gage technology [2].In 1999, the American Binsfeld engineering company launched TorqueTrak 9000, which is a fully digitized battery powered radio torque telemetry system. In 2002, the Binsfeld company developed a TorqueTrak Revolution torque on-line telemetry system to achieve non-contact induction power supply [3].…”
