Improved GNN based on Graph-Transformer: A new framework for rolling mill bearing fault diagnosis

Transactions of the Institute of Measurement and Control
The structure of the rolling mill system is complex and the operating conditions are changeable. Therefore, the interdependence between the data needs to be fully considered in the fault diagnosis of the rolling mill.

A Correlation-Based Distributed Fault Detection Method and Its Application to a Hot Tandem Rolling Mill Process

IEEE transactions on industrial electronics (1982. Print), 2020
In a hot tandem rolling mill (HTRM) process, the operating performance of mill stands can determine the quality of steel products, thus, should be properly monitored. Unlike previous work, which focused on a single stand or multiple stands together, this

Choice of steel for rolling mill rolls

Metal Science and Heat Treatment, 2009
The most important properties of test Cr–Ni–Mo–V-steels, answering the main requirements specified for roll steels are studied: quenchability, hardenability, tempering stability, mechanical properties and impact strength, contact fatigue resistance. Dependences on roll cooling rate are determined for these properties.

Adaptive neural torsional vibration suppression of the rolling mill main drive system subject to state and input constraints with sensor errors

Journal of the Franklin Institute, 2020
Torsional vibration often occurs in rolling mill drive system, which seriously affects the product quality accuracy and the service life of transmission equipment. This paper studies the adaptive neural torsional vibration suppression control problem for

Optimal Detection Schemes for Multiplicative Faults in Uncertain Systems With Application to Rolling Mill Processes

IEEE Transactions on Control Systems Technology, 2020
In rolling mill processes, changes of operation conditions, mismatching of controller parameters, and aging of system components will cause multiplicative faults, which may considerably affect the system operation and the quality of steel products.

Improving the durability of rolling-mill rolls

Metallurgist, 2010
This article examines methods of making rolling-mill rolls composed of hard alloys based on tungsten carbide. A new design is proposed for a compound roll to be used for the rotary rolling of semifinished products made of refractory metals. The roll includes a steel body and a hard-alloy insert.

Electric-driven rolling mills

Proceedings of the American Institute of Electrical Engineers, 1909
The first electric-driven steel rolling mill in the United States was installed about four years ago by the Carnegie Steel Company at their Edgar Thomson Works. Since then a number of other electric mill drives have been installed and run with entire success, a noteworthy example being found at the steel plant at Gary, Indiana.

Dynamic analysis of vibration stability in tandem cold rolling mill

Journal of Materials Processing Technology, 2019
Tandem cold rolling mills are comprehensive dynamic systems coupling with structure and rolling technology. A frequent problem is mill chatter, often occurring when rolling hard, thin materials at high speed and affecting the quality of the strip.
