摘要
介绍了邯钢邯宝炼钢厂IF钢生产设备及工艺,分析了IF钢生产过程氮的主要来源,提出了防止IF钢增氮的主要措施。研究表明,通过增大入炉铁水比、防止过程返干、减少转炉后吹、加强出钢口维护、优化精炼工艺控制、防止二次氧化等措施可以将IF钢中的氮含量控制在较低水平。
It is introduced the equipments and process for IF steel in Hanbao,analyzed the main source of increased nitrogen in production of IF steel,proposed the main measures to prevent that. It is showed in research that with measures： increasing hot metal ratio charged,preventing process returning dry,reducing reblowing in converter, strengthening maintenance of tap hole, optimizing refining process control,preventing secondary oxidation,the nitrogen content in IF steel can be controlled at a lower level.
