本系统采用了先进的微孔流化床技术,保证了喷粉工艺的稳定;另外,根据我国的国情和该厂的实际情况,大胆采用未除湿的压缩空气作为喷粉载气,不仅大大地节省了生产成本,同时在我国北方气候条件下,也保证了喷粉工艺要求,是我国在高炉铁水喷粉处理中使用压缩空气载气最早和最好的。另外,当时炼铁和铸造行业不少人对喷粉增硅生铁的性能和生铁质量持怀疑态度,针对这种担心,我们开展了对喷粉增硅生铁性能研究,结果发现在成
The system uses advanced microporous fluidized bed technology to ensure the stability of the dusting process; In addition, according to China’s national conditions and the actual situation of the plant, the bold use of non-dehumidified compressed air as a carrier powder carrier, not only greatly Save the production cost, and at the same time ensure the requirement of dusting technology in the northern climates of our country. It is the earliest and best use of compressed air carrier gas in blast furnace hot metal dusted treatment. In addition, many people in the iron-making and casting industries were skeptical about the performance of powder-added silicon-added pig iron and the quality of pig iron at that time. In response to this concern, we conducted a study on the properties of dust-
