摘要
针对小方坯内裂纹缺陷对铸坯质量的影响,确定了内裂纹在线评判函数。依据工艺参数对内裂纹缺陷的影响程度,对评判函数中的权重提供了分配方案。以小方坯连铸机的实际生产为样本,收集连铸生产工艺参数,进行离线验证。系统判定结果与传热模型的计算结果基本吻合,达到了预报和分析连铸坯质量的目的。
The on-line judging function of small sized square billet inner crack quality is defined though analyzing the effect of parameters on the quality.The distribution of parameter influencing referential priority value is provided.Some process parameters are collected in billet production and the judging results of inner crack are verified by off-line test.It was shown that the judging results can meet the calculating results of heat transfer model.It can achieve the goals of the forecast and analysis the quality of continuous casting billet.
