高温炉渣流动特性的冷态模拟

The Cold Flow Test on Blast Furnace Slag

为了研究高温炉渣的流动特性,设计一套离心粒化系统对其进行冷态模拟研究,以甘油代替高温炉渣作为模拟介质,采用高速动态摄影系统对不同结构的粒化转盘在不同转速下的甘油流动和破碎状态进行测定,分析转盘的直径、深度和转速对粒化效果的影响规律。结合理论和实验结果分析,不同的转杯转速、直径和深度会影响液膜的分裂模式,从而影响粒化的效果。该结论为后续的工业化应用提供参考。

A cold flow experimental study has been carried out on blast furnace slag by the centrifugal granulation system,and glycerol is used as simulate medium instead of blast furnace slag. An experimental test has been performed,during which the flowing and broken state of glycerol were measured by means of super speed dynamic film system for different disks in the different speeds,while the influence of operation parameters such as diameter,depth and speed of rotating disk on granulation process analyzed. Results show that different diameter,depth and speed can influence split types of liquid film,which will result in different granule diameters. This conclusion provides reference for industrialized application.
