蓄热式加热炉节能管理与操作浅析

Brief Analysis on Energy-saving Management and Operations of Regenerative Heating Furnace

文章针对包钢长材厂1号线蓄热式加热炉吨钢燃耗明显偏高的现象,根据坯料在加热炉内的传热情况,从加热炉管理与加热炉操作两方面进行了详细分析,得出燃耗偏高的原因。根据蓄热式加热炉的工作原理和操作特点有针对性地提出了细化、强化加热炉热工管理、提高热装率、减少热损失、控制排烟温度、合理控制炉膛压力等一系列改进措施及操作优化,有效地降低了煤气消耗,节约了生产成本,取得了一定经济效益。

In this paper,the causes for higher burnup are obtained by analyzing the management and operations of heating furnace in detail based on the heat transfer of billet in heating furnace aiming at the phenomenon that the burnup per ton of steel of regenerative heating furnace in 1#production line of Long Products Plant of Baotou Steel is obviously higher.A series of improvement measures and operation optimizations such as refining and strengthening the thermal management of heating furnace as well as improving hot charging rate,reducing heat losses,controlling exhaust gas temperature and reasonably controlling furnace pressure are put forward based on the working principles and operating features of regenerative heating furnace so that the gas consumption is effectively reduced,production costs are saved and certain economic benefits are obtained.
