本文描述了鞍钢炭砖综合炉底破损特点(炉底侵蚀较浅,环形炭砖破损严重),重点分析了环形炭砖断裂的原因.指出炭砖断裂除与热应力、铁水渗透、碱金属侵蚀、炭砖及砖缝质量等因素有关外,与时间因素也有密切关系.认为炭砖破损大致可分为潜伏期、破坏期、稳定工作期.文章对鞍钢综合炉底现存问题进行了探讨.认为通过采取综合措施问题可以解决.建议制订一项有关延长炉底炉缸寿命的政策,以便巩固成绩,并优选出一批超强化、超炉龄的高炉。
This article describes the characteristics of the comprehensive bottom of Ansteel carbon brick damage (shallow bottom erosion, ring-shaped carbon brick damage is serious), focusing on the analysis of ring carbon brick rupture reasons that the carbon brick rupture in addition to thermal stress, molten iron penetration, alkali corrosion , Carbon brick and brick quality and other factors, but also with the time factor is also closely related to that carbon brick damage can be divided into the incubation period, destruction period, stable working period.This article discussed the existing problems of comprehensive bottom of Ansteel, It is suggested that a comprehensive policy should be adopted to develop a policy on extending the life of the hearth in order to consolidate the achievements and to optimize the production of a number of blast furnaces of super-enhanced and ultra-long service life.
