A Method for Predicting the Defect Length of Copper-Aluminum Sandwich Rolling Composite Strip Head

Abstract

The invention provides a method for predicting the defect length of a copper-aluminum sandwich rolling composite strip, which includes: obtaining parameters of a defect length prediction model of a copper-aluminum sandwich rolling composite strip, and based on the copper-aluminum sandwich rolling composite strip head defect length prediction model parameters, the thickness of the initial rolled composite strip, the half thickness of the initial rolled composite strip, the thickness of the initial upper strip, the half thickness of the initial inner strip and the half thickness of the final rolled composite strip are obtained, according to The thickness of the entrance and exit of the rolling composite is obtained to obtain the pass reduction rate. By establishing a copper-aluminum sandwich rolling composite strip head defect length prediction model, the parameters of the copper-aluminum sandwich rolling composite strip head defect length prediction model are brought into the copper-aluminum sandwich rolling composite strip head defect length prediction model. The sandwich rolling composite strip head defect length prediction model can obtain the predicted strip head defect length. From this, the defect length of the composite strip head can be predicted, thereby greatly increasing the output and reducing unnecessary cutting losses.

Description

Technical field: [0001] The invention relates to the field of defect prediction of copper-aluminum sandwich rolling composite tape head, in particular to a method for predicting defect length of copper-aluminum sandwich rolling composite tape head. Background technique: [0002] In industrial aluminum-copper-aluminum sandwich rolling and compounding, because the aluminum strip is softer than the copper strip, the aluminum strip will be deformed first and will extend along the rolling direction. At the same time, due to the position of the copper strip during rolling, It is between the two layers of aluminum strips and does not directly contact the upper and lower rollers, so the copper strips will have a certain relative slip before compounding, which requires prediction of the length of the compounded lead defects. [0003] However, in actual production, most of the prediction methods used are empirical formulas without theoretical basis, which may reduce the accuracy of co...
