最近几年,已开发出直接确定钢水中化学元素浓度的激光技术。KRUPP PILOT SYSTEM就是应用于炼钢车间的80吨转炉的激光技术,简称LIESA(Laser Induced Emission Spectral Analysis,激光感应发射光谱分析)。LIESA的测量原理是高功率的N_d:YAG激光通过转炉侧壁上的窄通道聚焦于熔融钢水面上,激光束产生热等离子体,产生的光由具有高 In recent years, laser technology has been developed to directly determine the concentration of chemical elements in molten steel. KRUPP PILOT SYSTEM is the laser technology used in the 80-ton converter of a steelmaking plant, referred to as LIESA (Laser Induced Emission Spectral Analysis). LIESA measurement principle is high-power N_d: YAG laser through a narrow channel on the converter side of the focus on the molten steel surface, the laser beam to generate thermal plasma, the light produced by the high
