摘要
炼钢-连铸过程是一个复杂的过程,钢水需要选择符合工艺要求的钢包作为存储设备,并按照生产计划进行.钢包选配时,钢包的属性众多,选配目标相互冲突难以同时满足;钢水的钢种属性众多导致脱碳钢包选配的约束复杂,选配优化是一个具有多冲突目标优化问题.首先,采用一阶规则学习法提取关键属性作为性能指标,包括钢包温度最高、钢包使用次数最多、钢包材质等级最低和钢包下水口数量,以钢包温度、使用次数、钢包材质、钢包水口使用次数、滑板和框架使用次数为约束,建立钢包选配模型.然后,采用最小一般泛化规则学习法提取钢包选配规则,针对多种调度顺序策略和选配优先级组合进行了仿真实验;最后,给出了基于规则优先级的启发式钢包选配方法,并进行了工业应用.结果表明:提高了钢包选配准确度,减少了在线钢包数量和日钢包维护次数,提升了炉次生产效率.
The steelmaking-continuous casting process is a complex process.The molten steel needs to select the ladle as a storage device that meets the technological requirements and carry out according to the production plan.When the ladle is matched,the properties of the ladle are numerous,and it is difficult for the matching targets to meet each other at the same time.The steel with many properties lead that the ladle selection constraints are complicate.The optimization of the matching is a multi-conflict target optimization problem.First of all,using the first order inductive learner method to extract the key attributes as the performance indicators,including the highest temperature of the ladle,the highest number of ladle used,the lowest grade of the ladle and the number of ladle outlet,the ladle temperature,the number of ladle,ladle material,the number of skateboarding and frames to be constraints,and establish the ladle matching model.Then,the least general generalization method is used to extract the rules of ladle selection,and the simulation experiments are carried out for many scheduling order strategies and matching priority combinations.Finally,a heuristic ladle matching method based on rule priority was given,and carried out industrial applications.The results show that the accuracy of ladle selection is improved,the number of using ladle and the number of maintenance ladle are reduced.The production efficiency of heat is improved.
