本发明公开了一种转炉底吹供气元件透气效果的在线监测方法与装置，属于冶金技术领域，解决了现有技术中底吹供气元件的透气效果判断的准确性和精确性较差的问题。本发明的方法包括如下步骤：获取畅通度数据、冷却比数据和覆盖渣层高度数据，根据畅通度数据、冷却比数据和覆盖渣层高度数据计算透气效果评价参数，透气效果评价参数大于第一阈值，说明转炉底吹供气元件通畅；第二阈值≤透气效果评价参数≤第一阈值，说明转炉底吹供气元件轻微受阻；透气效果评价参数＜第二阈值，说明转炉底吹供气元件严重受阻。本发明的方法与装置可用于转炉底吹供气元件透气效果的在线监测。

The invention publics an online monitoring method and device for the ventilation effect of the bottom blowing gas supply component of converters, which belongs to the field of metallurgical technology, and solves the problem of poor accuracy and accuracy of judgment the ventilation effect of bottom blowing gas supply component in the prior art. The method of the invention includes the following steps: obtaining the data of unblocked degree, cooling ratio and covering slag layer height, calculating the evaluation parameter of ventilation effect according to the data of unblocked degree, cooling ratio and covering slag layer height, If the evaluation parameter of ventilation effect is bigger than the first threshold, it indicates that the bottom blowing gas supply component of converters is unblocked; If the second threshold ≤ the ventilation effect evaluation parameter ≤ the first threshold, it indicates that the bottom blowing gas supply component of converters is slightly blocked; If the evaluation parameter of ventilation effect < the second threshold, it indicates that the bottom blowing gas supply component of converters is seriously blocked. The method and device of the invention can be used for online monitoring of the ventilation effect of the bottom blowing gas supply component of converters.
