介绍了某厚板连续热镀锌退火炉生产线的设计特点,并对无氧化加热炉NOF(Non-Oxygen Furnace)段作了重点论述。结合无氧化加热炉在生产过程中对气氛、温度要求的特殊性,详细阐述了该段气氛及温度合理控制的方法。
The design features of a continuous hot galvanizing annealing furnace for a thick slab are introduced. The non-Oxygen Furnace NOF (Non-Oxygen Furnace) section is emphatically discussed. Combined with the particularity of the requirements of atmosphere and temperature in the production process of an oxidation-free heating furnace, the method of reasonable control of the atmosphere and temperature in the section is elaborated.
