昆钢新区2500m~3高炉炉墙结厚的原因,主要是原燃料质量差、生产系统不匹配、冷却系统的缺陷等。通过采取加强原燃料的监控与管理、精细化操作、加强重点设备管理、加强炉前管理、定期做好排碱工作、合理调整冷却制度、利用休风机会校正风口中套等预防炉墙结厚的措施,2500m~3高炉炉体第9~14段冷却壁温度稳定正常,高炉炉墙结厚的情况没有再发生,炉况稳定顺行,各项技术经济指标比较理想。
The reasons for the thick wall of 2500m ~ 3 blast furnace in Kunming New District mainly include the poor quality of raw fuel, the mismatch of production system and the defects of cooling system. Through measures such as strengthening the monitoring and management of raw materials, refining operations, strengthening the management of key equipment, strengthening the management of furnaces, regularly discharging alkali, adjusting the cooling system reasonably, and using the windshield to correct tuyere jackets, etc., , The temperature of the stave of Stoves 9 ~ 14 of 2500m ~ 3 blast furnace was stable and normal, the situation of blast furnace wall knot did not happen again, and the furnace condition was stable and stable, and the technical and economic indexes were ideal.
