长江钢铁新建3号高炉开炉装料过程中,采用了激光检测技术,根据料流宽度、料流轨迹、料面形状、FCG曲线等重要布料参数,制定了较合理的开炉布料矩阵;高炉点火后,随着风量、批重及焦炭负荷的增加,依据实际炉况变化及布料仿真数学模型的计算结果,通过定量化的布料数据分析,实时有效地对布料矩阵进行了调整。与传统的借鉴经验及定性摸索方式开炉相比,数字化布料技术更有助于操作人员定量化掌握布料规律,实现高炉顺利达产。
In the blast furnace loading process of No. 3 blast furnace at Changjiang Steel, the laser detection technology was adopted. Based on the important fabric parameters such as the flow width, the flow path, the shape of the material surface and the FCG curve, a reasonable opening matrix was developed. The blast furnace After ignition, with the increase of air volume, batch weight and coke load, the fabric matrix was adjusted in real time and effectively according to the actual furnace condition and the simulation results of fabric simulation. Compared with the traditional reference experience and qualitative exploration mode, the digital cloth technology can help operators to quantitatively grasp the fabric law and achieve the smooth blast furnace production.
