太钢5号高炉在低冶炼强度条件下操作制度的探索与优化

Exploration and Optimization of Operating System of TISCO No. 5 BF under the Condition of Low Smelting Intensity

针对太钢5号高炉在低冶炼强度的生产条件,通过稳定炉料结构和优化布料矩阵,调整送风面积和合理配置长短风口,调整热制度和造渣制度,控制铁水温度为1 480～1 500℃,维持m（Mg O）/m（Al_2O_3）〉0.5,控制炉前出铁炉数等措施,实现高炉稳定顺行和节能降耗。

Aiming at TISCO No. 5 BF under the production condition of low smelting intensity, through the stability of burden structure and optimization of material matrix, by adjusting air distribution area and the length of the rational allocation of tuyere, adjusting the thermal system and slag making system, the control of hot metal temperature for 1 480 ～1 480 ℃, maintaining m（Mg O）/m（Al_2O_3） 0.5, the control of iron-smelting casting number and several measures, the stable operation of blast furnace BF and energy saving and consumption reducing are realized.
