摘　　要：针对碳素生产特别是煅烧针状焦生产过程中,容易混入耐火材料杂物的问题,提出了利用X射线杂物检测器进行自动检测的方案。研究了单能谱和双能谱X射线在杂物检测器中的应用,发现双能谱X射线检测方式不但具有黑白图像,还能获得带有物质元素信息的伪彩色图像,可以将各种尺寸的耐火砖颗粒和石油焦颗粒区分开。To the problem that refractory impurities are easily mixed in the production of carbon,especially calcined needle coke,an automatic detection scheme using X-ray debris detector is proposed.The application of single energy spectrum and dual energy spectrum X-ray in debris detector is studied.It is found that dual energy spectrum X-ray detection method not only has black-and-white image,but also can obtain pseudo color image with material element information,which can distinguish refractory brick particles and petroleum coke particles of various sizes.
