攀钢炼钢综合化验中心是为炼钢厂生产服务的，炼钢厂各生产工序如脱硫、提钒、炼钢、炉外精炼（ lf 、 rh ） 、连铸等，都必须通过取样、化验分析来实时获得铁水、半钢、钢水以及提钒钒渣、炉渣等化学成分来指导、优化生产。 |
| 9. | Vanadium is important and valuable in steel - making , electronic production and national defence industry etc . now , the operation pattern of refining vanadium in our nation is based on human experiences , and the automation degree is still at a low level . operation mode based on human experiences is one of the main reasons make the quality of semi - steel and vanadium product unstable . in developed contury such as russian , static model was used to control the process of vanadium refining
我国目前的转炉提钒为人工操作模式，由操作人员根据经验和感觉进行操作，自动化水平低，存在着钒渣质量和半钢质量不稳定的问题；在国外，俄罗斯等一些国家已经在使用静态模型对提钒过程进行控制，取得了较好的效果，但是这些模型大都是根据复杂的物理化学规律研制的机理模型，要求有非常稳定的生产流程和工艺条件，对于铁水成分、生产设备等变化的适应性差，不但移植困难，而且模型价格异常昂贵。 |
