Abstract

The physical and mathematical model were established based on the principles and heat transfer features of the OCC to investigate the effects of some variables

including cooling distance

pulling velocity and internal-wall temperature in mold

on the position and shape factors of liquid-solid interface during OCC process.The optimized processing parameters and the feature data of liquid-solid interface in the condition of optimized processing parameters were described.The influencing orders of processing parameters on the features of liquid-solid interface were determined

verifying by practical production.
