New crown setup model of CVC hot strip mill

Journal Article


Abstract


  • A new crown setup model of CVC Hot Strip Mill (HSM) was developed according to the field condition of Bao Steel Inc., China. The scale of the proportional crown value fluctuation of the whole HSM was calculated in the beginning and then it was assigned to each stand according to the proportion of the reduction ratio of this stand to the whole reduction ratios. As a result, the crown after each stand can be calculated. With the appropriate setup of the proportion crown and the crown, to each stand, keeping the flatness under control and the on-gauge plate can be achieved during the CVC Hot Strip Mill. A software was developed based on the new crown setup model together with the roll elastic deformation model, work roll thermal crown model, CVC work roll shifting model and load distribution model. The software can be used to simulate the crown setup and roll shifting of Hot Strip Mill offline. The software was tested in the field condition and the results were much better than the previous field setup.
