韶钢7号高炉(2200m3)采用铜冷却壁、陶瓷杯、薄炉衬结构等先进技术。开炉1年后,由于原燃料质量变差、操作制度调整不及时、风口中套变形、风机频繁故障等原因,导致炉况失常。通过合理调整装料制度、改善原料质量,优化风口布局,狠抓管理等措施后,炉况逐步恢复正常。
Shaogang 7 blast furnace (2200m3) using copper stave, ceramic cup, thin lining structure and other advanced technologies. After 1 year of operation, due to the deterioration of the quality of the raw fuel, the adjustment of the operation system is not timely, the deformation of the tuyere sleeve and the frequent fan failure cause the furnace condition to be abnormal. By reasonably adjusting the loading system, improving the quality of raw materials, optimizing the outlet layout and paying close attention to management, the furnace condition gradually returned to normal.
