Modern simulation technology can help to optimize refractory solutions for the continuous casting process in general and adapt them to tailor-made customer solutions. Several examples of design developments are given, and the validation by plant observations and on-site measurement technology is shown.
In 2011, Nucor Steel Tuscaloosa replaced its Steckel drums and upcoiler DC motors with new 1,500-kW AC induction machines fed from new voltage source inverters. As a result, the voltage variations were reduced during heavy load from the DC drives, and additional overload torque was available for the main stand DC motors. This paper describes the control strategy used in the converter and the improvement of the power system performance.
Contingency planning for continued business operations is a multi-faceted risk management function. While natural disasters cannot be avoided, their impact may be somewhat lessened if businesses are better prepared. This paper identifies pre-planning exercises companies can complete to help restore electrical distribution and control equipment efficiently and safely.
