Analysis of Roll Temperature Field and Thermal Crown in TSCR

摘要

Roll thermal crown variation in thin slab continuous casting and rolling (TSCR) is an important factor which affects strip profile. Prediction of roll thermal crown variation in rolling is a difficulty and weakness for many kinds of heat transfer ways and many physical parameters could not be confirmed well and truly. Setting up roll temperature field model which consider different affection factors is the key to solve the difficult problem. A new simplification method of analyzing roll temperature field is presented. Transient roll temperature field and thermal crown in TSCR are simulated by ANSYS software. Transient thermal contact and complex boundary condition are considered. The prediction results of thermal crown are good agreement with measurement data.
