梅山高炉四年多维护炉缸的实践表明，在炉役后期，当炉缸侵蚀严重，热流强度较高时，由于坚持添加钒钛物料，并辅之以与其配套的维护炉缸的相关技术措施，在高炉安全运行的情况下，维持了较高的生产水平，做到不减产或少减产，使高产与长寿在精心维护好炉缸的前提下达到统一。 Meishan blast furnace for more than four years to maintain the practice of the hearth shows that in the later stage of the furnace, when the hearth erosion serious heat flux higher, due to insist on adding vanadium and titanium materials, combined with its supporting the maintenance of hearth related technical measures , The safe operation of the blast furnace to maintain a higher level of production, so that no less or less cut, so that high yield and long life in the well-maintained hearth under the premise of uniform.
