The fly-slide floating theory of the head-disk in magnetic hard-disk recording devices is used for the fluid flow of tape-casting, in order to satisfy the requirements of high precision and super thin electronic ceramic film in tape casting. Based on the structure and working theory of the tape-casting head and the roll, the physical model, Newton liquid Reynolds equation and the dynamic equation in the tape-casting are established. With the help of the above mentioned models and equations, the transient response in various technological parameters is achieved by MATLAB software. The rules that technological parameters influence on the stability of tape-casting system are analyzed and the choice gist about technological parameters for improving the stability of tape-casting system is obtained.
