A new data-driven reference vector-guided evolutionary algorithm has been successfully implemented to construct surrogate models for various objectives pertinent to an industrial blast furnace. A total of eight objectives have been modeled using the operational data of the furnace using 12 process variables identified through a principal component analysis and optimized simultaneously. The capability of this algorithm to handle a large number of objectives, which has been lacking earlier, results in a more efficient setting of the operational parameters of the furnace, leading to a precisely optimized hot metal production process. 相似文献

基于低温炼铁技术酸性高炉渣流动性的实验研究 总被引:1,自引:0,他引:1
用分析纯化学试剂配制高炉炉渣,研究基于低温炼铁技术MnO和Na2CO3含量对高炉渣熔化温度及黏度的影响,并用XRD分析缓冷后熔渣的矿相。结果表明:MnO能促进高炉渣形成大量的钙镁、钙铝黄长石,同时形成含锰的复杂化合物,这些物质能有效降低高熔渣的熔化性温度及黏度;当MnO质量分数在2.0%左右、1 400℃时,高炉渣黏度能达到0.564 Pa.s;Na2CO3能扩大炉渣的软熔区间,但对高炉渣的黏度影响不大。 相似文献

A low-temperature process for iron-making, using mixed pellets of magnetite and domestic coal with an organic binder was investigated. Reduction tests performed in an induction furnace resulted in a product direct reduced iron (DRI) containing 75–80% metallic iron. The coal energy consumption of 23.71?GJ/ton DRI compares favorably with current DRI processes, although the total energy consumption of 33.65?GJ/ton is relatively high for iron-making. The use of low-grade coal as a reductant may improve the economics of the process as high-grade coking coal supplies dwindle worldwide. 相似文献

铁水包在线个数和铁水包周转频率对于炼铁厂物流有着重要影响。以铁水包高炉配罐制度为切入点,分析了重庆钢铁公司新区的铁水包运转数据,并使用Plant Simulation软件建立3座高炉—3座转炉模式下炼铁厂物流仿真模型,研究了在"3+1+X"制度和优化后的动态制度下,重钢铁钢界面铁水包合理在线个数和铁水包物流参数。结果表明:与"3+1+X"制度相比,动态制度可以减少在线铁水包1个,并减少平均空包时间达20 min,对炼铁厂物流的紧凑、高效和低耗运行有着重要的意义。 相似文献
