摘　　要：笔者采用专门设计的热流传感器对弧形连铸圆坯结晶器的热流进行在线检测。结果表明:沿结晶器的高度和周向热流的分布是瞬间变化且不均匀的。温度的在线检测不能代替热流的在线检测,后者可更准确和直接地反映结晶器传热和坯壳厚度的均匀性;同时在线检测结晶器的温度和热流有可能对结晶器的设备状态(如结晶器的安装状况和水垢状况)实现在线预测。The heat flux of curved mold for round casting was measured by special-designed heat flux sensor. The measured results showed that the vertical and horizontal profiles of heat flux are instantaneously variant and uneven. The online measurement of mold heat flux can not be replaced by online temperature measurement, the later can respond the uniformity of heat transfer and thickness of solidified shell more accurately and directly, and online temperature and heat flux measurement of mold can be used to foresee the mold conditions such as fix and scaling of mold.
