高炉冷却装置是维护炉体结构的重要设备,经使用一段时间后其水管由于水的杂物沉积和结垢使其冷却效率急剧降低。为改善其工作效率,必须定期清洗。过去按结垢程度不同曾普遍采用“水顶”、气“扫”和酸洗方法清洗。这些方法除效果不够理想外,尚存在工艺和成本高的问题。最近我们采用了国外行之有效的砂洗方法,收到了良好效果。 1.砂洗的工艺流程及要求砂洗工艺流程及设备如图1所示。在 Blast furnace cooling device is an important equipment to maintain the structure of the furnace, after a period of time its water pipes due to debris and water deposition and scaling of its rapid decline in cooling efficiency. To improve its work efficiency, it must be cleaned periodically. In the past by different levels of scaling has been commonly used “water top” gas “sweep” and pickling method of cleaning. In addition to the effect of these methods is not ideal, there are still problems of high technology and cost. Recently, we have adopted a well-established sanding method abroad and received good results. 1. Sanding process and requirements Sanding process and equipment shown in Figure 1. in
