Heating process analysis and system design of continuous annealing furnace for cold-rolled stainless steel

基于冷轧不锈钢连续退火工艺及制度分析,对其连续退火炉加热系统进行了设计,通过表面能量平衡方程和能量守恒方程可计算出炉长配置及燃烧功率配置。通过实际算例与实际运行情况对比分析,得到该设计方法是有效的,能够完成从产品大纲、工艺分析基础到机组加热系统集成、布置、设备总体布置的设计过程,为后续冷轧不锈钢连续退火炉加热系统二级模型提供了理论基础。

Based on the continuous annealing process and system analyses for cold-rolled stainless steel,the heating system of continuous annealing furnace was designed,and the furnace length configuration and the combustion power configuration were respectively calculated by the surface energy balance equation and the energy conservation equation.By comparison and analysis of the actual calculation example and the actual operation,it verifies that the design method is effective and has the ability to complete the design process from the product outline and process analysis basis to the unit heating system integration,arrangement and overall arrangement of equipment.Thus,it provides a theoretical basis for the secondary model of the heating system of the cold-rolled stainless steel continuous annealing furnace.
