Optimization of oriented and non-oriented silicon steelstrips manufacturing process using simulationin COMSOL and robust algorithms

This paper relates to an improved process for producing oriented and non-oriented silicon steels sheets or strips of standing magnetic qualities using simulation in Comsol and calculation in Matlab software. Silicon steel which have so far been used for iron cores of transformer and electrical machines. Manyattempts have been made to control the crystal orientation of silicon steel sheet in accordance with its use. Since the silicon steel has a body cubic centred crystal structure wherein three mutually vertical and transverse directions of easy magnetization or cube axes <100> are present and as a consequence thereof, if a magnetic is applied parallel with one of this directions, the amount of energy necessary to magnetize the silicon steel core will be at a minimum. These requirements are discussedin this paper and some suggestion to improve the production lines and process in annealing furnace, cold rolling and coating are presented. To clarify the claim simulation in Comsol and Matlab has been performed.
