Abstract
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 100° C. to 1100° C. The method includes measuring at least two radiation intensities at different wavelengths, in a range from 1 to 5 μm, emitted by the heated steel strip estimating the temperature of the heated steel strip based on the at least two measured radiation intensities and a reference radiation intensity for at least a reference wavelength, estimating an emissivity of the heated steel strip, and estimating the oxide thickness, of the heated steel strip using the estimated emissivity.
