宝钢不锈钢2号高炉炉役末期护炉实践

Practice of Maintenance at Later Stage of Campaign in No.2 BF of Baosteel Stainless Steel Company

针对宝钢不锈钢2号高炉炉役末期炉缸侵蚀加剧的状况,通过加强炉缸状态监控,并采取了强化炉缸冷却、炉芯温度的管理、减风控冶、休风镇静,使用风口喂含钛包芯线等一系列护炉和技术改造措施,延缓了炉缸的进一步侵蚀,做到了在顺行的基础上护炉,在安全的前提下最大限度地优化各项经济技术指标。

Considering continuously developed hearth erosion, countermeasures were conducted to prevent further erosion, such as supervisory controlling, intensifing of hearth cooling, improving the management of core temperature, reducing the blast volume and controlling smelting, blowing down and keeping stable, feeding titanium-containing materiel cored wire at tuyere. On the premise of safety, smooth operation was realized, resulting in maximum optimization of the economic and technical indexes.
