首秦1号高炉自2015年9月4日检修后送风以来,结合检修前后送风系统及操作炉型变化,在强化原燃料管理、出铁管理的基础上,通过上下部调剂的合理匹配,实现了大渣比下重负荷冶炼。2015年12月份为限制产量,风口面积缩小11.38%,通过合理选择送风参数,保持了煤气分布的稳定,同时进一步加重焦炭负荷至6.01,在平均渣比433.30kg/t的条件下,燃料比平均499.17kg/t。
Shouqin No. 1 blast furnace since September 4, 2015 after the repair of air supply, combined with maintenance before and after the blast system and operating furnace type changes in strengthening the management of raw materials, iron management, based on the upper and lower adjustment of a reasonable match , To achieve a large slag than the heavy load smelting. In December 2015 to limit production, the tuyere area was reduced by 11.38%. By reasonably selecting the air supply parameters, the gas distribution was kept stable while the coke load was further increased to 6.01. With an average slag ratio of 433.30 kg / t, the fuel ratio Average 499.17kg / t.
