摘要
基于Mie散射理论,建立了连铸二冷区水雾粒子的消光模型,分析了水雾粒子的散射特性,计算了水雾粒子在各粒径和各辐射波长下的消光特性.结果表明,水雾粒子为具有非灰性、参与性特点的弥散系.在模拟工况下,水雾散射角介于0°～2.5°,为强烈前向散射.消光作用随粒径增大而增强,粒径分布是影响水雾消光特性的直接因素.
The surface temperature of continuous casting slab was an important parameter of production control,but its value can not be measured accurately for the execrable environment in the second cooling zone.This research was based on Mie scattering theory,the extinction model of water spray particles in the second cooling zone was set up,their scattering properties were analyzed,the extinction characteristic in various particle sizes and each radiation wavelength was computed.The results indicated that the water...
