攀钢四高炉高效长寿生产技术分析 总被引:1,自引:0,他引:1
攀钢四高炉第一代炉役无中修生产14年6个月6天,单位容积产铁量为9 367.2t/m3,最高的年均利用系数超过了2.3t/(m3·d).高炉的高效长寿生产,除了受设计、装备水平影响外,与炉料条件、高炉操作、日常维护等也密切相关.为了进一步提高钒钛磁铁矿冶炼水平,从炉料条件、高炉操作、日常维护等几方面对攀钢四号高炉第一代炉役实现高效长寿生产的有益经验进行了总结.认为:精料工作、长期稳定顺行的操作及炉役中后期对高炉冷却设备和炉体的及时维护是高效长寿生产的重要保障. 相似文献

The 45°scattering of a femtosecond (60 fs) intense laser pulse with a 20 nm FWHM (the full width at half maximum) spectrum centered at 790 nm has been studied experimentally while focused in argon clusters at intensity - 1016 W/cm2. Scattering spectra under different backing pressures and laser-plasma interaction lengths were obtained, which showed spectral blueshifting, beam refraction and complex modulation. These ionization-induced effects reveal the modulation of laser pulses propagating in plasmas and the existing obstacle in laser cluster interaction at high laser intensity and high electron density. 相似文献
