Magnetic forces on electrodes and steel bath in the EAF
The computation of the magnetic forces on EAF electrodes and the steel bath is complicated and has not been performed realistically to date. Simulations have to be based on a proper geometrical model and need to consider that the current density in the high current system and in the steel bath is extremely inhomogeneous. For the first time a realistic computation of the magnetic forces is presented in this article, applying the FNM computation system.
Significant increase in converter availability and safety thanks to new torque support
Italian stainless steel company Acciaierie Valbruna implemented a new torque support for the 70 t AOD converter vessel at its steelmaking plant in Vicenza. After installing the new electrohydraulic torque support a substantial reduction in uncontrolled vibrations of the gear unit and the converter vessel has been achieved. The measurements were performed in the presence of a specialist consultant from the University of Padua.
Pipe ID 4.0: comprehensive process control system for the manufacturing of large pipes
A comprehensive process control system for the manufacturing of large-diameter spiral-welded pipes features a track and trace system, monitoring of the overall equipment efficiency (OEE), condition monitoring, smart diagnostics and power monitoring. The production data acquired includes all planned and unplanned downtimes including their causes, fault messages, target/actual production and the quality of the parts. In this way, the system operators gain a basis for calculating the OEE.
Modernization of the hot strip mill at Tata Steel Port Talbot works
Tata Steel has invested more than £14 million in the modernization of its hot strip mill at Port Talbot, Wales (UK), allowing it to manufacture more higher-value steels for customers. The hot strip mill underwent 18 days of maintenance. Now, Tata Steel has installed the transfer bar cooling system to increase the volume capacity of the hot strip mill by more than 150,000 t/year.
