摘要
利用红外热像仪和红外测温仪测定了钢锭凝固过程中铸模外表面的温度分布,再通过模拟实验对测温结果进行修正。着重对钢锭表面纵向各代表位置点温度随时间变化的趋势及规律进行了分析,探讨了其与钢锭凝固过程的关系,对可能导致的铸锭缺陷进行了预测。通过数值模拟及生产情况的验证,证明了利用红外测温对钢锭表面测温进行内部质量判定的可行性,可为钢锭凝固模拟与质量控制提供参考。
Infrared thermal imager and infrared thermometer were used to measure the ingot mold outer surface temperature distribution in solidification process, and the measured results were corrected by simulation experiment to get real values. It is focused on the tendency and regularity of temperature change along the vertical direction of ingot surface with time. The possible casting defects were predicted. Combined with the software simulation and the production situation, it can be proved that infrared temperature measurement to be used for ingot internal quality judgment is feasible in casting. It can provide a way for ingot solidification simulation and ingot quality control.
