国内炼制电工纯铁传统的作法是用电炉冶炼,甚至用电渣炉或真空感应炉来冶炼。能否用平炉或转炉用冶炼呢?太钢已用转炉来冶炼,革新了工艺。包钢七八年以前曾不少次用30吨平炉来冶炼,但未获得成功,轧废较多。去年以来,我们又在平炉内炼制了两批工业纯铁,由于用稀土处理,使纯铁的红脆性得到了解决,轧制成材率和纯铁的性能得到提高。文中提出了进一步如何提高电磁性能的措施。
The traditional practice of refining domestic electric pure iron is electric furnace smelting, and even using electroslag furnace or vacuum induction furnace to smelt. Can use open hearth or converter smelting it? TISCO has been used to smelter converter, innovation process. Baotou seven or eight years ago, many times with 30 tons open hearth furnace smelting, but did not succeed, rolling waste more. Since last year, we have also refined two sets of industrial pure iron in open hearth furnaces. Due to the treatment of rare earths, the red brittleness of pure iron has been solved. The rolling yield and the properties of pure iron are improved. The paper proposes further measures to improve the electromagnetic performance.
