摘要：

轧钢加热炉耐材在检修后需要进行烘烤，以保证耐材在后续高温使用过程中不会产生裂纹和坍塌。本文就轧钢加热炉耐材烘烤采用常规方式和煤气烘烤方式进行了阐述，同时根据耐材检修情况制定大修及烘烤曲线，总结烘烤过程中的注意事项，取得了较好的实践效果。

Abstract:

The steel rolling heating furnace refractory needs to be dried after maintenance to ensure that the refractory will not crack and collapse during the subsequent high temperature process.In this paper, the processes of refractory drying in steel rolling heating furnace with firewood and gas are described and summarized.At the same time, the overhaul and drying curves are formulated according to the condition of refractory maintenance, and the attention details in the drying process are summarized.Good practical results are obtained.

Key words: Heating furnace, Refractory, Overhaul, Drying
