Modeling the spread of hot-rolled Ni-based alloy plates

摘要

The width spread of Ni-based alloy plates in the rolling process is studied.An equation for describing the rolling spread of Ni-based alloy plate is proposed based on production data and the Bachtinow equation,which cannot fully account for the compositional variability of Ni-based alloys.To address this,a new coefficient for alloying is added to the equation based on production data.By adding alloying coefficients,it is possible to improve the prediction accuracy for the rolling spread of Ni-based alloy plates and thus better control the width of the rolling spread of different steel grades.
