The practice of furnace condition restoration in No.1blast furnace of Xiang-gang was summarized.In the second generation of No.1, the furnace condition fluctuates after the opening of the furnace, and various technical indicators decline sharply.By taking the lower adjusting tuyere area, charging system, operating in the center of the upper steady stability before furnace thermal system and slag phase, strengthening operation management, and attaches great importance to the furnace type management measures, implements the blast furnace condition, technical indexes rising steadily.%针对1号高炉第二代炉龄开炉后炉况出现波动, 各项技术指标大幅下滑等问题, 通过采取下部调整风口面积、上部稳中心的装料制度、操作上稳定热制度及渣相、加强炉前操作管理、重视炉型管理等措施, 实现了高炉炉况恢复, 各项技术指标稳步提升.
