ALEXANDRIA, Va., Oct. 6 -- United States Patent no. 12,754,073, issued on Oct. 6, was assigned to ArcelorMittal (Luxembourg).
"Method for estimating the temperature and the oxide thickness of a steel strip" was invented by Gwenael Le Noc (Ars-sur-Moselle, France) and Morgan Ferte (Jury, France).
According to the abstract* released by the U.S. Patent & Trademark Office: "The present invention provides a method for estimating anoxide thickness and temperature of a heated steel strip undergoing a heat treatment performed at a temperature from 100deg C. to 1100deg C. The method includes measuring at least two radiation intensities at different wavelengths, in a range from 1 to 5 micro metre, emitted by the heated steel strip estimating the te...
