宝钢3号高炉1994年9月20日投产,至今已稳定运行了18a,创造了多项宝钢高炉技术经济指标纪录和国内最长寿高炉记录。经过多年来的探索与实践,形成了具有3号高炉自身特点的长寿设计和操作维护综合技术。主要长寿措施有:合理的炉型和冷却系统设计;强化入炉原燃料质量管理,优化操业配置,确保炉况稳定顺行;保证足够的冷却强度、改善并稳定纯水水质;采取安装微型冷却器、硬质压入、人工造壁、更换破损冷却壁、稳定铁口深度、适当压浆、完善炉缸监控等多种长寿维护措施,确保炉体炉缸状态良好,从而有效延长高炉寿命。
Baosteel No.3 blast furnace was put into operation on September 20, 1994 and has been operating steadily for 18 years. It has created many records of technical and economic indexes of BF and the record of the longest blast furnace in China. After years of exploration and practice, it has formed a long-life design and operation and maintenance comprehensive technology with its own characteristics of No. 3 blast furnace. The main long-lived measures are: reasonable furnace and cooling system design; strengthen the quality management of raw materials into the furnace to optimize the operation and configuration to ensure stable and steady furnace conditions; to ensure adequate cooling strength, to improve and stabilize the quality of pure water; to install miniature Cooler, hard press-in, artificial wall, replacement of damaged cooling stave, stable iron mouth depth, proper grouting, perfect hearth furnace monitoring and other maintenance measures to ensure that the furnace hearth furnace in good condition, thus effectively prolonging the life of the blast furnace .
