摘要
以厚度规格为0.8 mm的SPCC冷轧钢带为例,利用ANSYS有限元分析软件分析了钢卷在全氢罩式炉退火过程的温度和层间压应力分布情况,得出在冷却阶段卷心温度为650℃左右和450℃左右,层间压应力分别大于30 MPa和35 MPa时,冷轧钢带极易产生粘结缺陷。通过优化退火工艺,降低了冷轧钢带粘结缺陷率,提高了罩式炉的生产效率。
Take the cold - roiled strip of 0.8mm SPCC as an example, process temperature and interlaminar stress distribution are analyzed by using ANSYS finite element analysis software analysis steel coil in annealing furnace annealing. It is obtained that the cold rolled strip is easy to emerge the bond defect ＇ when in the cooling stage of high temperature around 600℃ and 450℃, interlaminar stress were greater than 30Mpa and 35Mpa respectively. And the production efficiency is improved through optimizing the annealing process, reduce adhesion defect rate.
