Internal oxidation and formation of Si/Al-enriched oxide bands in the scale of electrical steel grades
Source abstract
Abstract
Oxidation during steel hot rolling is responsible for various surface defects. Local enrichments of oxygen-affine alloying elements such as silicon or aluminium can cause such defects by complicating oxide scale removal. In this paper, correlations between the temperature profile during oxidation and enrichment formation in electrical steels are investigated. Diffusion and reaction simulations using the numerical Crank-Nicolson-scheme are evaluated by comparing them to laboratory-scale oxidized samples. Furthermore, analytical approximations (spectral methods) are investigated as an alternative approach, focusing on trade-offs between accuracy and calculation times. A link between heating periods during oxidation and Si/Al-rich bands in the scale was established.
