简介了300t 转炉的3台OG 装置及投产以来运行情况;根据生产实际数据,提供了该系统回收煤气和蒸汽的节能和消除烟尘改善环境的效果。由于操作人员的努力,充分发挥了OG 装置的功能,达到并超过了设计指标,使宝钢炼钢工序能够达到负能耗状态。文中叙述了两年多操作中遇到的各种问题及其对策,并提出了今后的改进课题。 This paper introduces the operation of three OG units in a 300t converter and their operation since commissioning. Based on the actual production data, the system provides the effect of recovering the energy saving of gas and steam and eliminating the soot to improve the environment. Due to the efforts of operators, the function of OG plant has been fully utilized and the design indexes have been met and exceeded, which enables the process of steelmaking in Baosteel to reach the state of negative energy consumption. The article describes the problems encountered in more than two years of operation and its countermeasures, and put forward the future improvement issues.
