Abstract
The whole production process of 50W800 grade non-oriented silicon steel hot rolling-cold rolling-annealing was observed,and the influence of its composition,structure,impurities and other factors on the iron core loss of silicon steel was analyzed.The results can be summarized as follows that:(1)The iron core loss can be reduced by increasing the silicon content within a certain range.(2) After annealing,the crystal grains become larger and the crystal defects are reduced,thereby reducing the iron loss.(3)The iron core loss is reduced by reducing the content of elements such as carbon,nitrogen,and sulfur.(4) The strength of strip steel can be enhanced by adding trace elements.
