摘要: 铸坯生产过程参数实时采集与精确定位是铸坯质量在线判定及生产过程参数在线优化的基础。通过现场试验总结了一种铸坯质量相关生产过程参数定位方法, 该方法通过对浇铸长度修正, 能够将实时采集的铸坯生产过程参数精确定位到铸坯切片, 克服了传统铸坯生产过程参数定位的缺陷与不足。此外将精确定位的铸坯生产过程参数保存到以铸坯切片为标识的信息组中, 在此基础上采用LM-BP算法建立表面纵裂纹判定模型对众多铸坯切片信息组分析。结果表明, 通过该方法采集的数据准确性较高且模型命中率较高。Abstract: Real time collection and precise location for production process parameters of continuous casting slab is the basis for the online determination of continuous casting slab quality and the online optimization of production process parameters.On the basis of the actual production experience,a new location method for production process parameters of continuous casting slab has been developed. The method,which based on the casting length modification,can locate the real time production process parameters to section of continuous casting slab and thus overcomes shortages of the traditional location method. In addition,the accurate locate production process parameters can be saved into information group identified by section of continuous casting slab.Based on this,model of continuous casting slab quality determination by LM-BP algorithm has been established and used to analyze information groups of section of continuous casting slab.The experiments demonstrated that the data collect method is of high accuracy and the model is of high accuracy.
