介绍了通过控制BRP位置间接控制烧结终点的方法。通过计算BRP位置,实时调整烧结机速度和烧结机台车压入率厚度,使烧结终点稳定在系统设定的范围之内,形成了基于专家知识的烧结终点模糊控制系统。该模型被应用后,可根据实际情况调整烧透点的位置,保证了烧结生产正常运行,改善了烧结矿各项技术指标,2009年节约成本2310万元。 相似文献

The process state of iron ore sintering is characterised via the bed permeability, the temperature rising point, the burn rising point and the burn through point. The intelligent control strategy of sintering process based on fan frequency conversion is put forward. The stability of process state is firstly evaluated based on the knowledge of domain experts. If process state is fluctuating, an expert controller is activated to realise a normal production. If process state becomes steady, then a fuzzy controller is activated to obtain the optimisation of process state and reduce the power consumption of main exhaust fan. The closed-loop control of sintering production showed that the system can realise the optimisation of sintering process state, and reduce the energy consumption of sintering production while ensure the stability of sinter quality indices, it theoretically saves power consumption of 1×104?kWh every day. 相似文献
