西林钢铁集团公司炼铁总厂自从两座高炉大修扩容改造后,随着精料水平的不断提高,在两座高炉进行了冶炼低硅生铁的生产实践,其中L04和L08铁占有率8月份突破99%,操作中生铁含硅量按0.35%～0.50%控制,取得了增产降焦的效果。但在生产运行过程中,由于生铁硅含量低、流动性好,导致铁水罐冲刷侵蚀严重,铁水罐使用寿命由原来的铁水粘罐、罐容小而甩罐变为因铁水
Xilin Iron and Steel Corporation Iron and Steel Plant since the two blast furnace overhaul expansion transformation, with the continuous improvement of the level of fine materials, in two blast furnace smelting low-silicon pig iron production practices, including L04 and L08 iron breakthrough in August 99%, the amount of silicon in the operation of pig iron is controlled by 0.35% ~ 0.50%, and the effect of increasing output and reducing the coking has been achieved. However, during the production and operation, due to the low content of silicon in pig iron and the good fluidity, the molten iron tank erosion erosion is serious. The service life of the hot metal tank is changed from the original hot metal tank.
