1 概述 1999年末到2000年初,随着唐钢生产规模的不断扩大,钢铁生产对氧氮的需求也日益增加,主要表现为钢的日产量达11000t,至2001年日产钢达到14000-15000t,转炉的溅渣护炉工艺的使用日益频繁和重要。为此,氧氮供应不足且氧气的连续性生产与炼钢用氧不均衡性之间的矛盾成为制约唐钢生产上水平的关键因素之一。在当时的情况下,尽管杭氧六千改造即将投产,且1~#空分设备改造也提上日程,但如何利用现有装置多产氧,稳供氧,降低氧气生产成本,减少氧气放散就成为一个急需解决的课题。经过对各机组的分析、论证,认为:当前1~#空压机生产效率高,产气量大,2~#空压机
1 Overview From the end of 1999 to the beginning of 2000, with the continuous expansion of the production scale of Tangshan Iron and Steel, the demand for oxygen and nitrogen in steel production is also increasing, mainly as the daily output of steel up to 11000t, to 14000-15000t Nissan Steel in 2001, The use of slag splashing process is becoming more and more frequent and important. Therefore, the shortage of oxygen and nitrogen supply and the continuous production of oxygen and steel oxygen imbalance between the constraints become the production of Tang Steel, one of the key factors in the level of production. In the circumstances, even though the retrofit of HangXu 6,000 is going to start soon and the retrofitting of 1 ~ # air separation plants will be put on the agenda, how to utilize the existing devices to increase oxygen production, stabilize oxygen supply, reduce oxygen production cost and reduce oxygen release It has become an urgent issue to be solved. After the analysis of each unit, demonstration, that: the current 1 ~ # air compressor production efficiency, gas production, 2 ~ # air compressor
