摘要
高炉冶炼过程中提高风温使得煤气发生量减少,理论燃烧温度增加,风口前燃烧的固定碳减少,从而降低焦比,优化高炉各项技术指标。攀钢二高炉通过2007年的年修,对热风炉进行改造,使风温从年修前的1190℃增加到目前的1230℃左右,风温长期维持在较高水平,促进了高炉各项技术经济指标的进步,使得钒钛磁铁矿冶炼技术得到提高。
Improving blast temperature during furnace smelting process make the amount of gas reduced, the theoretical combustion temperature increased, fixed carbonair combusted before tuyere reduced, thereby reducing the coke ratio in blast furnace, optimizing each technology index. In 2007, according to the reform for hot blast stove, the blast temperature of blast furnace No. 2 increased from 1190℃ before the annual repair to 1230℃ and maintained at a high level, which promoted the progress of various technical and economic indexes of blast furnace and made the V-Ti magnetite smelting technology improved.
