摘　　要：带钢在连续退火前,无论是呈板形良好的平直状态,还是具有某种瓢曲浪形,但是经过连续退火后其往往不能保持原来的几何状态,会发生明显的大挠度变形。通过深入现场对这一现象长期跟踪,建立了退火炉内带钢热力学行为的力学模型,并运用ANSYS有限元软件仿真研究了其变形机理和各影响因素的影响大小和规律。研究结论对于宝钢2030连续退火线改进工艺、减少热瓢曲有指导作用。No matter what flatness of strip is whether flat or defective at anneal furnace entrance, strip can not keep it's original shape and a remarkable large deflection has took place at anneal furnace exit. By tracking this phenomenon at 2030 continuous anneal line, the mechanics model of strip thermodynamics behavior in continuous anneal furnace is builded. The mechanism of flatness changes and the variations of these changes with the contributing factors are researched by the famous finite element software--ANSYS. Conclusions are achieved from the study, which may be used to improve technologies and decrease strip heat-buckling of 2030 continuous anneal processing line and hot galvanization line.
