Abstract Annealing furnaces are used to heat steel in order to change its chemical structure. In this paper we model an electric radiant furnace. One of the major defects in steel strips processed in such furnaces is a wave-like pattern near the edges of the strip. apparently due to extra heating near the edges. https://www.alarecre.com/NFL-Atlanta-Falcons-Double-Vision-iPhone-13-Pro-MagSafe-Case-p92343/
