对宁钢1号高炉全湿熄焦生产的应对措施进行了总结。针对1号高炉全湿熄焦生产前期,炉况波动大,生产指标变差的状况,采取加强原燃料管理、选择合理的送风制度、优化装料制度、稳定炉温、强化炉前作业等措施,炉况后续逐步调整恢复,高炉热负荷平稳,燃料消耗可控。在恢复干熄焦55%的比例后,高炉处于高产、低耗的稳定顺行状态,日产量维持在6000~6050t/d,燃料比控制在515kg/t左右。
The countermeasures of the quench coke production at No. 1 BF in Ninggang Iron and Steel Co. Ltd. were summarized. In view of the situation of No.1 blast furnace wet quenching and coke production, large fluctuations in furnace conditions and deterioration of production targets, the Group will take measures to strengthen the management of raw fuel, select a reasonable air supply system, optimize the loading system, stabilize the furnace temperature, Measures, followed by the gradual adjustment of the furnace recovery, the blast furnace heat load steady, fuel consumption controllable. After the recovery of the proportion of 55% of CDQ, the blast furnace in a stable, high-yield, low-consumption steady state, the daily output remained at 6000 ~ 6050t / d, fuel ratio control at about 515kg / t.
