摘　　要：为提高热处理炉的加热效率,提出在炉顶增加喷嘴的设计方案,利用ANSYS Fluent软件模拟了炉顶喷嘴不同射速下(0~120 m/s)炉内流场分布,并对不同射速下(30~210 m/s)炉内钢板的温升变化进行了分析。结果表明,在炉顶增加喷嘴后,炉内流场分布更加均匀,且随喷嘴射速增加,气体流动更稳定且均匀,炉内温度分布也更加均匀;不同喷嘴射速下,炉内钢板的升温速率随着射速的增加而增加,但超过某一阈值后,钢板的升温速率提升有限。可见,炉顶增加喷嘴及优化射速参数可显著提高热处理炉的加热效率。To improve the heating efficiency of the heat treatment furnace,a design scheme of adding nozzles on the top of furnace was proposed.The flow field distribution inside the furnace at different firing rates(0-120 m/s)of the furnace top nozzles was simulated by ANSYS Fluent software,and the temperature rise changes of the steel plates inside the furnace at different firing rates(30-210 m/s)were analyzed.The results show that after adding nozzles on the top of furnace,the flow field distribution inside the furnace is more uniform,and as the nozzle firing rate increases,the gas flow becomes more stable and uniform,and the temperature distribution inside the furnace becomes more uniform.At different nozzle firing rates,the heating rate of the steel plate in the furnace increases with the increase of firing rate,but beyond a certain threshold,the increase in heating rate of the steel plates is limited.It can be seen that adding nozzles on the top of furnace and optimizing the firing rate parameters can significantly improve the heating efficiency of the heat treatment furnace.
