一、前言电工纯铁是工业上应用较早的一种软磁材料。由于它具有高的导磁率和良好的电磁性能(矫顽力较低),因此,在电器、电讯、电工仪表等部门获得广泛的应用。我公司从1955年开始生产这种产品,原系电炉冶炼。但随着电工纯铁需要量的日益增加,仅依靠电炉冶炼便不能满足要求。近几年来氧气顶吹转炉在我国发展很快,现已成为我国炼钢生产的重要方法之一。这种工艺生产效率高、成本低、钢质较纯净,尤其是钢中含氮低,冶炼工艺比电炉简单,炼电
First, the preface Electrical pure iron is a soft magnetic material used earlier in the industry. Because of its high permeability and good electromagnetic properties (low coercivity), it has been widely used in electrical appliances, telecommunications, electrical instrumentation and other departments. My company started production of this product from 1955, the original Department of smelting furnace. However, with the increasing demand for pure iron, it can not meet the requirements only by electric furnace smelting. In recent years oxygen top blown converter has developed rapidly in our country, and now it has become one of the important methods of steelmaking in our country. This process has the advantages of high production efficiency, low cost and relatively pure steel, especially low nitrogen content in steel, simple smelting process compared with electric furnace,
