高炉入炉焦炭水分的变化,会引起高炉焦炭装入量、炉温的波动,直接影响炼铁的焦比、产量、质量、过去、由鞍钢化工总厂定时、定点取样烘干称重,将焦炭水分报给高炉。因受各种因素的影响,很难确切掌握一批焦炭各部水分的分布以及同此引起的炉况波动.中子测水是放射性同位素的应用技术之一,利用中子源发出的快中子与氢原子核碰撞散射而减速,变成慢中子(热中子)的现象来进行的——测量热中子密度分布,确定被测焦炭中水分的多少.中子水分仪操作简单,测量迅速,准确,并可在线连续测量入炉焦炭的水分,投资少,效益大,为高炉操作者提供了有力的监测手段,并为高炉炉况的计算机控制创造了有利条件.
The change of blast furnace coke moisture will cause blast furnace coke loading, temperature fluctuations, a direct impact on the ironmaking coke ratio, yield, quality, in the past, from the Ansteel Chemical Plant regular, fixed-point sampling drying weighing Coke moisture is reported to the blast furnace. Due to various factors, it is difficult to know exactly the distribution of moisture in a number of coke departments and fluctuations in the furnace conditions caused by the same.The neutron measurement of water is one of the application techniques of radioactive isotopes, and the use of neutron source to emit fast neutrons Collides with the hydrogen nucleus and scatters and slows down and becomes a phenomenon of slow neutrons (thermal neutrons) - measuring the thermal neutron density distribution and determining the amount of water in the coke under test. The neutron moisture meter is simple to operate and measures rapidly , Accurate, and can be measured online continuously into the coke moisture, less investment and high efficiency, providing blast furnace operators a powerful means of monitoring, and for the blast furnace condition computer control has created favorable conditions.
