石横特钢2~#高炉护炉操作实践

Furnace Protection Operation Practice of No.2 BF in Shiheng Special Steel

石横特钢2~#450 m^3高炉在第二代炉役生产过程中,针对两个测温点温度升高、炉腰炉腹部位西侧炉皮频繁发红的情况,通过含钛物料入炉、提高铁水钛含量的方法进行护炉操作,及时采取冷却壁栽棒和炉体灌浆等设备维护措施,优化调整操作制度,加强安全生产,实现了高炉的安全稳定运行并取得了较好的技术经济指标。

In the second generation production process of No.2 450 m^3 blast furnace in Shiheng Special Steel, due to the temperature increasing of two measurement points, the parts of furnace waist abdomen bit and the west of the furnace hearth were heated redness frequently, the maintenance measures were taken. Such as the protection furnace operation was taken using the titanium-containing material charged into the furnace to improve the titanium content of molten iron, the planting sticks was take and furnace cooling wall grouting timely etc. The operating system was optimized and adjusted, the safety of production was improved, the safe and stable operation of the blast furnace and good technical and economic indicators were achieved.
