摘　　要：针对影响加热炉L1数据跟踪系统准确性的因素,分别从步进梁速度控制精度、步距累积误差和跟踪系统自身性质误差三方面进行分析,并结合工程实际经验逐项优化修正。通过优化,极大提高了L1跟踪数据系统的准确性,从而解决了由于跟踪数据偏失所造成的跟踪与顺序控制相互脱节、步距控制缺乏依据、误差累积过大无法出钢等一系列问题,也为L2模型控制提供了基础的生产数据条件,间接保障了加热模型的稳定运行,提高了板坯加热的质量。According to the factors which influence the accuracy of L1 data tracking system of heating furnace.The precision of the walking beam speed control system,the cumulative deviation of step distance and the errors of the system are analysed and optimized based on engineering respective practice.The optimization method greatly increases the accuracy of L1 data tracking system,and solves the problems including the disjoint of tracing and sequence control caused by data deviation,the step distance without enough evidence,and production stopping caused by the accumulated errors.Results show that the tracking system works accurately,which provides basic data for L2 model control,and ensures the stability of heating model indirectly and improves slab heating quality.
