Based on the principle of heat transfer

solidification theory and slag-smelting

a finite differential model was developed to analyze the heat and solidification and to control process of continuous casting

considering the relationship between thermo-physical parameters of steel with temperature.The rational temerature and secondary water quantity distribution can be realized by optimizing the secondary water based on continuous casting principle and objective control method

obtaining the optimum billet quality

and aiming at the solidification characteristics of different steel series

the design of mold flux was conducted.The calculated value is well in agreement with the measured ones.It was researched to the effects of some parameters

including pouring temperature

drawing velocity

secondary water quantity

on the surface temperature of billet

liquid-core length and solidified shell thickness as well as effects of pouring technology on properties of mold flux.
