摘要
为解决连续退火过程中带材跑偏、瓢曲等问题,结合单锥度辊及双锥度辊在防治带材跑偏与瓢曲方面的优势与不足,并考虑炉辊热凸度的影响,设计了一套全新的炉辊辊型曲线。以带钢稳定通板作为辊型优化设计的目标函数,建立了一套适用于连续退火炉内炉辊辊型的优化模型。试验结果表明:优化后的辊型使带钢跑偏距离及瓢曲指数明显下降,保证了机组高速、稳定的连续生产。
In order to solve the problems of strip deviation and buckling in continuous annealing processes,combined with advantages and disadvantages of single taper rollers and double taper rollers in prevention and treatment of the buckling and strip deviation,a new set of furnace roller profile curves was designed,and a set of optimization models suitable for furnace rollers was established in continuous annealing furnaces,with travelling stability of the strips as objective function of roller profile optimization designs.After field production practices,test results show that the roller profiles after optimization make the strip deviation distance and the buckling index decrease significantly,the high-speed and stable continuous productions of the unit are guaranteed.
