在现代冶金工业中,低铝的硅铁主要用于电气工业的钢材,如制造变压器和电动机的硅钢片等。随着炼钢工业的发展及其质量的提高,对硅铁质量也提出了更高的要求。现在,我国和苏联等国家的硅铁标准中,对含铝量已分别重新作了规定。例如,日 In the modern metallurgical industry, low-aluminum ferrosilicon is mainly used in the electrical industry of steel, such as the manufacture of transformers and motors of silicon steel and so on. With the development of the steelmaking industry and the improvement of its quality, the quality of ferrosilicon is also put forward higher requirements. Now, China and the Soviet Union and other countries in the ferrosilicon standard, the content of aluminum has been re-provisioned. For example, day
