本文是对长治钢铁厂6t氧气顶吹转炉扩容工程的技术总结。实践证明,在全厂生铁和轧材均大于炼钢能力的情况下,通过转炉容量的扩大,使钢产量增加19%以上,主要指标均有改善,增加利税470多万元/年,而投资仅240万元。为国内同样条件下的转炉钢厂的挖潜改造创出了一条路子,提供了有益的经验。 This article is a technical summary of Changzhi Steel Plant 6t oxygen top blown converter expansion project. Practice has proved that in the whole plant pig iron and rolled materials are greater than the steelmaking capacity of the case, through the expansion of converter capacity, the steel production increased by 19% or more, the main indicators have improved, increase profits and taxes more than 4.7 million yuan / year, and investment Only 240 million yuan. For the domestic conditions of the converter steel mills to tap the potential to create a way to tap, and provide useful experience.
