| Abstract: | There are some problems m the tandem lower ash conveying Oewce oi the dry dusting system for No.4 blast furnace in the old area of Laiwu Iron ＆ Steel Co., such as the device can only be removed in a single row mode for maintenance, serious wear and blockage of ash pipes. After the corresponding reconstruction, a large amount of nitrogen has been saved. It has greatly reduced failure rate of the ash pipes and labor intensity of maintainers, and ensured safe running of the equipment. |
