摘要
文章以某钢厂1780 mm轧钢加热炉和炉内钢坯作为研究对象,按加热炉热工过程将计算单元划分成钢坯入口、钢坯加热和钢坯出口三部分,应用集成计算平台中Ansys软件对每个计算单元氧化烧损及其产生的原因、影响因素以及特征规律进行分析并得出相应的控制措施。通过采取保证临界装钢温度、优化残氧量目标值以及防止炉头吸入冷风三类控制措施,氧化烧损率降低13.3%,对同类型轧钢加热炉降低氧化烧损具有示范作用。
In this paper,the reheating furnace and reheating slab of a 1780 mm hot strip mill(HSM)is taken as research object,and based on reheating process of the heating fuenace,the calculation unit is divided into three parts:inlet,reheating and outlet.In the intergrated computing platform,Ansys software is applied to analyze the scale formation and its causes,influencing factors,and mechanism in each calculation unit,and corresponding control measures are obtained.By adopting three control measures,including ensuring the critical slab charge temperature,optimizing the target residual oxygen content,and preventing the furnace head from inhaling cold air,the scale formation rate was reduced by 13.3%,which has a demonstrative effect on reducing scale formation in the same type of HSM reheating furnace.
